Description

A kind of new purposes that is dissolved in the compositions of the sterol compound in the oils and fats

Technical field

The present invention relates to a kind of tissue physiology repairs and the regenerated compositions of organ dysfunction, more specifically, relate to a kind of compositions, it can be by inducing internal in-situ versatility regeneration of stem cells, make it propagation, realize mammal and/or the physiological reparation of tissue and the human organ that regeneration has complete function.The invention still further relates to using method and/or other purposes of said composition.

Background technology

The technological progress of large-scale production cell culture and biomaterial aspect, make the development post of tissue engineering industry, these products all are external, i.e. the external generation of animal or human's body or synthetic, be transplanted to then on one's body the host, reach the purpose of tissue repair or other treatment.

One of method of modern tissue engineering is that a kind of synthetic material is transplanted into human body, as structural support, and the growth of supporting tissue.For example, the α-BSM of Etex company (the said firm is positioned at Maryland, USA Cambridge) production The synthetic bone substitute can be applied to plastic surgery, dentistry and cranium face.α-BSM

Be a kind of minimum crystal shaped calcium phosphate, the composition and the structure of its imitation bone mineral composition levels.When this material mixes with salt, become pasty state, injectable enters in the space, also in the implantable, as plastic putty.In case this material is inserted the appropriate location, the rising of body temperature can make it hardening.As a result, implant has become a support, finally is absorbed, and is substituted by new osseous tissue.

The another kind of method of tissue engineering is to utilize the biological substrate opposite with synthetic, for the reparation and the regeneration of impaired or illing tissue provides basic.Get fresh human body corpse skin, by certain control device, promptly, remove the cell on skin and the corium, but do not change extracellular matrix and basement membrane complex, can be made into acellular skin matrix [referring to the article of Wainwiright: (1995), 21 phase 243-248 pages or leaves of Burns magazine].Use the same method for remedying the scarcity of human body corpse skin, adopting, also available fresh animal is made acellular dermal matrix [referring to the article of Liversey etc.: (1995), Transplantation magazine 60:1-9] as the Corii Sus domestica skin.LifeCell company (being positioned at New Jersey Branchburg) has invented with chemical method human body skin recently, produces human body skin substrate.By this chemical method, can remove all Skin Cells, but retains biological activity and structural dermal matrix.Someone thinks, a kind of like this tridimensional structure structural, that the intact acellular substrate of biochemistry can provide a kind of information is arranged, and forms and recovers at a normal regenerative response middle finger emissary vein.Acellular application on human skin substrate can be used as allograft, i.e. the graft that obtains from donor rather than this person of host.Substrate is freezing in liquid nitrogen, be broken into 100 micron granules then, the acellular blood vessel graft that these diameters are very little can be grown for changing into the cell of a certain particular type, with and/or at the various organs of external formation.These cells and organ are expected to as graft, treatment various diseases and the Insufficient body part of replacement.

The extracorporeal embryo development process has the foreseeability of not knowing, be expected untouchable.Embryonic stem cell is divided into a kind of cell of particular type or the condition unpredictable of organ.Research worker is found, keep undifferentiated relatively, the versatility state of the embryonic stem cell of cultivation, they just must express inherent transcription factor Oct4, and the basic extraneous signal [referring to (1998) magazines such as Nichols: Cell 95:379-391] that presses down compositions (LIF) from the cytokine leukemia that receives.When LIF withdrew from, the embryonic stem cell of cultivation can automatically aggregate into a lot of various types of tissues.Although the program of gene expression is similar to the typical case who grows animal a bit and breaks up the path in these cells, the initiation of these programs is confusing.

The neomorph that utilizes the stem cell of In vitro culture to carry out success clinically is faced with many obstacles.In a single day the stem cell of In vitro culture is transplanted to disease sites, just must be guided the phenotype that is divided into a certain specific part.Therefore in order to instruct the design of vitro tissue condition, need decipher completely this process desired signal.The experimental data that some research philtrums obtain shows technically, although by in culture medium, adding the leukemia inhibitor, can realize pluripotent human mesenchymal cell, mice neural stem cell and mouse embryo stem cell in external growth, but mouse embryo stem cell is the randomness differentiation in vitro and in vivo.Technical progress might make mouse embryo stem cell (ESCs) be induced to differentiate into versatility neurogliocyte forerunner external, and they are implanted in the insufficient rat brain of myelin.But, can they become the tissue of specific part when multipotent stem cells that as people these are gathered from specific tissue or that differentiation forms from external embryonic stem cell was implanted injured adult tissue? this problem still fails to obtain answer.

Up to now, for by repair the impaired tissue and the organ of dysfunction the In vitro culture stem cell, a large amount of financial resources and manpower have been dropped into.But, utilize this method, do not see successfully the regenerate report of human organ of an example so far as yet with complete function.For example, only can wound closure with the cutin stem-cell therapy wound surface of In vitro culture, but can not recover the physiological structure and the function of skin fully.Therefore, need urgently to invent new method, abandon above-mentioned strategy, for human health provides more benefit.

The present invention provides new method and new compositions for animal, particularly human physiological tissue repair and functional neomorph.The new invention of this novelty all has versatility in conceptive and practice, focus on the technology of inducing and breeding realization tissue repair and neomorph by the internal regeneration stem cell.

Utilizing skin---the organ of human body maximum is made model, and the inventor has showed clinically that damage or tissue and the organ lost can regenerate in position, promptly original in vivo has position regeneration.For example, the extensive deep burn patient, the major part of its skin is by major injury, functional defect, wound healing preventing from scar after the rehabilitation, skin comprise that the normal function of its adnexa all can recover.

By contrast, current method in tissue repair and the employing of neomorph field mainly concentrates on external, and promptly the outer organizational project of human body is transplanted.As what look back in background one chapter of the present invention, people have dropped into a large amount of effort, to designing from body and/or allosome tissue that human body or other animal come on one's body, so that they are implanted into human body, repair or the infull organ of alternative functions.Utilize this method,, on the expense of clinical effectiveness and material and manpower, exist serious restriction though obtained certain success.Even more noteworthy, still do not have evidence to show clinical up to now, utilize this method can make regenerated organ recover physiological function fully.For example, the extensive deep burn patient treats through this method, stays cicatrix after healing, and appearance is ruined to the greatest extent, more because all or part of forfeiture of skin function causes deformity.

The inventor thinks, utilizes method and composition provided by the invention, and the treatment by the mankind first gets involved the full functionality organ of can regenerating.The various tissues that constitute organ can be regenerated or reparation on physiological ground, and promptly their physiological structure and function reach fully and recover.In contrast be, with the wound surface of other method treatment, in most of the cases be the pathologic healing usually, i.e. the dysfunction of skin or weakening.This functional defect of perusal shows as the formation cicatrix, examines under a microscope, and can find that change has all taken place for skin quality, color, blood vessel differentiation, neural supply, reflectivity and biochemistry attribute.

1. adult tissue repairs and the basic principle of neomorph

The present invention has disclosed adult tissue original position reparation and regenerated basic principle in vivo, as shown in Figure 1.

1) General principle

From as a whole, if a regenerated environment is provided for the adult of growing fully, it has the ability to repair impaired tissue and regeneration organ.As shown in Figure 1, as to the replying of wound or other type damage, the remaining one-tenth living cells of damage organ can be activated, and oneself is converted into adult stem cell (ASCs), the i.e. homologue of embryonic stem cell.This inducing of adult stem cell makes them can provide neomorph required a large amount of polytype cell.

But these newborn stem cell are quite fragile, and cytotoxin that various environmental factorss produce and cell all easily cause the death of these stem cell to the runaway reaction of damage.As shown in Figure 1, under the suitable culture condition that the present composition provides, these adult stem cells are followed the fetal development stage just by the instruction of heritability sequencing, breed, develop into various versatility tissue stem cells.The capacity supply of various types of cells is guaranteed in the generation of this versatility functional organization stem cell, and these cells are to form physiologic sexual function to organize needed.

Referring to Fig. 1, under the optimum condition of culture that the present composition provides, these tissue stem cell hypertrophy spread, are divided into the specific cell type of specific type of tissue.The noble cells of particular type is got in touch each other by the cytoadherence of particular organization, forms cambium.The contact method of this particular organization cell is referred to as " cell connection " at this.Then, regenerated new organization is connected with tissue by the tissue that forms certain organs, and the organizational groups process of assembling of imitation period of development fetus, is combined into newborn organ.The connected mode of organizing of this certain organs is referred to as " tissue combination " at this in adult.

At last, the cambium in the organ of reorganization under the regulation and control of the present invention combination, reach maturity for one, have functional tissue, have the cell category and the quantity of physiologic equilibrium.Simultaneously, these tissues exchange by the tissue in the lived organ net, and experience is further reinvented, and finally form full functionality, sophisticated organ (Fig. 1).

Follow the regeneration approach of foregoing description, tissue impaired or that lose can be repaired, and recaptures their physiological structure and function.As do with human body skin model for example shown in, during the patient of the inventive method treatment skin major injury, needn't transplant through skin, healing can recover brand-new skin, skin comprises that the physiological structure of the various appendages of skin and function all can not lose.

The inventor believes, under suitable developmental condition, and the method for cultivating regenerated stem cell by internal in-situ, organ that can regeneration of damaged, and make it to recover fully its physiological structure and function.Under the regulation and control of endogenous provided by the invention and exogenous material, this regenerative process is spontaneous generation in vivo.Fundamentally, successful neomorph depends on the many cells adhesion of the correct particular organization of physiological, the many tissue assemblings and the in vivo homeostasis coexistence compatible with immunity of many organs of certain organs.

2) Redefining of " stem cell "

Based on this basic principle and clinical in the successful Application aspect the neomorph, the implication of stem cell has been had definition again in the present invention.

In traditional definition, stem cell should possess following Column Properties: 1) it is not self terminal differentiation, promptly is not in the least significant end of differentiation; 2) it can be without restriction, or divide in the vital stage of animal at least; 3) when it divides, each daughter cell both can remain the stem cell state, also can begin the process of irreversible terminal differentiation.[referring to cellular elements biology, Molecular Biology of the Cell, chief editors such as Alberts, the third edition (1994), 1155-1156 page or leaf, Garland Publishing company, New York and London]

According to this definition, the stem cell of from tissue, separating, for example the embryonic stem cell of separating from the inner cell mass of human body blastocyst is separated from a living person on one's body even be fully, then exist in external culture medium, they still are stem cell.These so-called stem cell though can divide without restriction and be divided into various types of histiocytes, fail to show the ability with full functionality human organ of regeneration, say nothing of living person of external regeneration.

For avoiding obscuring with the definition of traditional stem cell, the present invention is called stem cell " regeneration of stem cells ".This regenerative cell has following feature: it is present in (1) in vivo; (2) it is subjected to the physiology control of health and regulates; (3) tissue of it and health and organ coexistence; (4) it can constantly carry out cell division in vivo; (5) it has repair tissue, regeneration organ, the physiological structure that recovers the regeneration organ and the ability of function.

3) Intravital regeneration naturally

Human body has huge regeneration capacity.Tissue with cell renewal height ratio, all regeneration constantly in whole life process as blood and epithelium.Other tissue regeneration can occur as liver, skeleton, muscle, blood vessel and adrenal gland's cortex when sustaining damage.Liver is regenerated by compensatory hypertrophy, and other tissue may be to realize regenerating by increasing the tissue regeneration that mesenchymal cell derives from, activating deposit stem cell or CFU-GM, or realizes regeneration in regenerated tissue.For example, hematopoietic cell, as the T cell, the B cell, neutrophilic granulocyte, and erythrocyte is by the hematopoietic stem cell regeneration in the bone marrow.If pointed tip cut to terminal articulations digitorum manus, finger tip is still renewable.But, be that skeleton or muscle all can not be crossed gap regeneration, and after other organ such as skin, pancreas, heart and spinal cord sustained damage, more back regular meeting stayed scar tissue.

The uniqueness that discloses among the present invention and the focus of novel method is to utilize the inherent ability of health itself to carry out self-regeneration and regeneration.Under suitable physiological condition, as be immersed in the warm aseptic amniotic fluid, fetus can the normal healing wound surface, can not stay cicatrix, also can not lose function.Regrettably, the mankind that grow fully but are that existence is in diverse, a more hostile environment.Under external and intrinsic condition, the adult wound healing of nature and slightly different track of growth experience finally often stay cicatrix, and it is incomplete organ dysfunction to occur.This normal healing process is passive fully, is not subjected to the control of Therapeutic Method, is the process that a confusing cell proliferation, differentiation and regenerating tissues are rebuild.

4) The methodology of development in principle is used

The invention provides the method and composition of controlling tissue repair and the whole process of neomorph energetically.In this process, the least unit of cell---life is upset, and breeds, breaks up and be bonded to each other, and physiological ground is repaired damaged tissues or regenerated by various situations, as wound surface and the destructive tissue of disease.These nascent organizing then link together, and form the organ with complete function.

In order to realize this result on one's body, just need special, a positive human interventional therapy the adult.Total guideline of this measure of Zhan Shiing in the present invention is: 1) for the tissue of damage or damage, should keep the one-tenth living cells in the remaining tissue to greatest extent; 2) should remove non-viable non-apoptotic cell or tissue as early as possible; 3) activate and the proliferation regeneration cell imitation regenerative cell self an original physiologic condition planted agent; 4) regulator that regeneration organ application cell is grown and broken up is to instruct the correct physiology reparation of tissue.

Specifically, methodology of the present invention comprises following eight big technology, as shown in Figure 2.

A) The activation and the adjusting of adult stem cell (ASCs)

The versatility adult stem cell depends on the tissue stem cell that a) activates dormancy in the generation of body original position, and as the epithelium stem cell, they may be present in the knuckle position of hair follicle; B) induce the cell that has broken up fully oppositely to break up, change it into ASCs.

B) ASCs is the cultivation of original position in vivo

In physiological moist environment, cultivate fragile nascent ASCs, make it growth and directed differentiation fast.

C) The discharge of liquefaction and necrosis tissue and oozing out

When removing the slough of skin wound, do not adopt traditional debridement method, it is invasive surgical excision, but its going from the exterior into the interior ground is liquefied with the present composition, automatically ooze out slough from wound surface, thereby greatly reduce the danger that remaining one-tenth living tissue is produced physics or chemical damage.

D) Tissue in situ in the exogenous culture medium is cultivated

The invention provides exogenous culture medium, make cell ramp betwixt, the combination and mobile of ASCs and differentiation, thus the tissue that physiological ground reparation injured tissues or regeneration are lost.

E) Non-sterilization mode suppresses antibacterial toxicity

Do not take the mode of topical antibiotic killing bacteria cell to suppress to cause the antibacterial toxicity of traumatic infection, duplicate but allow bacterial cell to carry out heritability, under the environment that the present composition provides, change its form then, produce thereby reduce toxin, therefore can reduce the inflammation that bacteriotoxic immunoreation is caused because of health greatly.

F) The generation of the physiology moist environment of skin regeneration

The over-drying meeting of wound surface causes incrustation and damages into living tissue.The water evaporates that can prevent wound surface with the present composition, but with compare do dressing with vaseline, can not cause the excessive moisture of wound surface again.

G) The microcosmic of wound surface and external environment is isolated

Use the present composition at wound surface and can form the layer of transparent film at wound surface, it keeps apart wound surface and external environment, but alimentation composition and oxygen are penetrated in the beneath tissue.This semi-permeable film exactly likes amniotic membrane, and the environment that it held is a relative aseptic environments, is suitable for the regeneration of the inside tissue.Thereby tissue obtains regeneration and reconstruction according to a system that is similar to fetal development, forms a full functionality organ.

H) The regenerate required oxygen and the supply of nutrition

Various alimentation compositions provide through exogenous as a complete set of natural amino acid, polysaccharide, fatty acid and phosphate.Tissue under the required oxygen of cell growth can be penetrated into by this tunic.Simultaneously, antibacterial and other environmental contaminants are with to carry out organizing of wound healing isolated.

5) The inventive method and of the contrast of other method in technology

The method of the organ of the replace damaged of using clinically and tissue is organ transplantation and implants bionic device at present.The major defect of organ transplantation is donor shortage and immunosuppressive side effect.The shortcoming that the bionic device value is gone into is to produce the artificial material of endurance, intensity, form, function and the biocompatibility the same with born tissue.

At the regenerative medicine that nineteen nineties occurs, still under test at present, it focuses on two main policies: make every effort to form the cell transplantation of new tissue and the bioartificial tissue of the outer establishment of implant at transplantation site.

Cell transplantation comprises In vitro culture and the propagation of stem cell, and then the product that breaks up they or they is transplanted to the impaired position of organ.Though the progress that fertility is learned has made cell transplantation be expected to be applied to clinical, but still have the restriction of multiple reality, and clinical effectiveness is physiology and aesthetic also not fully up to expectations.One of them restriction of this method is to be difficult to differentiate and the separating multipotent stem cell in numerous tissues.Although cultivated versatility human embryo stem cell (ESC) recently be, still the directed differentiation of ESCs is a mystery.Though the result who gets is very inspiring, but still can not on function, be converted into people's autogenic therapy that people rely on from zoopery.For example, Mouse Neuron cell and neurogliocyte that external neural stem cell derives from, and at external myocardial cell from ESCs, when being injected into adult brain and heart, they can combine with surrounding tissue respectively.When the human neural stem cell of multipotency was injected into the mice brain of growing, they can move at whole brain, and break up at specific part.

Utilize the successful regeneration of the stem cell realization organ of In vitro culture, also face many obstacles.In a single day the stem cell of In vitro culture is implanted into affected areas, and they must be directed to specific phenotype differentiation.This just must decipher the required signal of this process fully, so that instruct design vitro tissue condition of culture.The testing data that some research worker obtain technically shows, although by in culture medium, adding leukaemia inhibitory factor, can realize versatility people mesenchymal cell, mice neural stem cell and mouse embryo stem cell in external growth, but mice ESCs breaks up with external equal randomness in vivo.Technical progress might make mouse embryo stem cell (ESCs) be induced to differentiate into versatility neurogliocyte forerunner external, and they are implanted in the insufficient rat brain of myelin.But when people implanted injured adult tissue with these multipotent stem cells that gather or that differentiate from external embryonic stem cell from specific tissue, whether they can become the tissue of specific part, and this problem still fails to obtain answer.

Transplanting the immunologic rejection that produces is another subject matter in the cell transplantation.Because the allos cell can be used in some examples (as, myeloid mesenchymal stem cell), the cells that great majority are transplanted will be allogenic.Research worker has attempted to adopt the strategy of hereditary change and cell biological, to promote allosome or xenotransplantation host's toleration, as being placed, diplontic somatic cell removes nuclear human body or other mammiferous germ cell, produce stem cell with consequent blastular, these methods have caused the concern to bioethics, and this is a more stubborn problem.

The artificial creature who is implanted in external establishment organizes and also faces many obstacles.For example, the used timbering material of synthesizing bionic implant promptly is a major challenge, because bionical implant needs the signal of accurate topography, surface properties, growth and differentiation, be beneficial to that cell moves, adhesion, propagation and differentiation, and have the plasticity that is moulded various tissues and organ shape.The current synthetic biomaterial that is using or testing comprises various potteries, polyurethane elastomer, polyester, polyanhydride and polyphosphazene.These materials provide the surface of mechanical support, mobile channel and adhesion for cell.

Opposed with the technical background of above-mentioned summary is to the invention provides a kind of inventive process of adult tissue's reparation and neomorph.This method and the popular external stem cell culture method formation sharp contrast that research worker adopted in this field at present, it pays close attention to the adult stem cell activation and the cultivation of original position in vivo.By utilizing inherent self-regeneration of health itself and regeneration capacity, this method provides a suitable condition for body's natural regeneration, and this is a required regenerative environ-ment of the healthy fetal development of imitation.The stem cell that compositions provided by the invention can activate dormancy breeds, or inducing adult histiocyte transformationization regeneration of stem cells, and keeps the active propagation of these stem cell and directionally be divided into the required all cells of internal in-situ regeneration.The new prescription of active ingredient promotes also to form that physiology is moistening, nutrition and homeostatic environment, to guarantee to organize reparation and the regeneration with organ, makes it to recover fully their physiological structure and function.

Shown in the back part of this description, this method successfully is applied to clinical, and the treatment organ is lost or Insufficient patient, as the people of deep burn patient, chronic ulcer patient, wounded patient, intestinal ulcer patient and trouble alopecia.After the method treatment, patient more back tissue obtains repairing, neomorph, and its physiological 26S Proteasome Structure and Function does not all have the loss of essence.

6) The application of principle in regenerative medicine

Under the guidance of basic principle that the present invention sets forth and method, people are envisioned that the present invention is widely used in cell fertility field and medicine and pharmacology practice, and it has shown success on animal model and human body therapy.

According to the strong evidence that experiment in vitro model and clinical trial are collected, the inventor believes, as long as suitable regenerative environ-ment is provided, as to the tissue repair signal, be the reaction of wound surface, the histiocyte of any organ all can be activated in the human body, generates regeneration of stem cells.With the early pregnancy stage fetus no scar to close wound healing different, the physiological tissue repair of the adult that realization is grown fully and the unique channel of functional neomorph, be to provide exogenous culture medium by internal in-situ, stimulate and keep the fast breeding and the directed differentiation of adult stem cell, and guarantee the correct assembling of various organ particular organization, and unlikely substantial losing appear on 26S Proteasome Structure and Function.

The inventor believes, although be difficult to demarcate and separating multipotent adult stem cell (ASCs), the tissue stem cell that can activate dormancy by internal in-situ with and/or the inducing adult histiocyte change ASCs (Fig. 1) into and produced adult stem cell.The basic principle of setting forth among new development aspect stem-cell research and the present invention is applied to test with the obtained data of clinical trial and has all proved this viewpoint recently.

Recently, in liver, pancreas and central nervous system, all found ASCs.From bone marrow, isolated mesenchymal stem cell, and evidence suggests similar cell even may be present in whole systemic connective tissue chamber.Research worker had once been searched for the position of ASCs on a large scale, and inferred that they may be present in the specific microhabitat.As in " embodiment " in detail described like that, behind full pachydermia layer burn, the control environment that utilizes the inventive method to provide can induce the mesenchymal cell in the fat deposit of skin corium to produce regenerated ASCs, the realization skin regeneration.

No matter the exact position of various ASCs where, method and composition provided by the present invention all can be used for swashing in vivo ASCs, full original position damaged tissue repair and regeneration function organ not in vivo.Can predict, the method for this novelty can be used for recovering mammal, the physiological structure of especially human intravital any tissue and any organ and function.Below several application examples will be described.

A) cultivate epidermal stem cells regeneration or upgrade skin by internal in-situ

Skin is the largest organ of animal, is made of exocuticle, corium and subcutaneous tissue, has the skin of physiological function to have three layers of tissue that interacts and have their own characteristics each on the structure normally.

Epidermis is a kind of constantly in renewal, stratified squamous epithelial tissue; most of cell of epidermis is that horn cell is arranged stratification, represents their different differential periods, and skin is a horny layer; separate as barrier protection health and external environment, and help to keep internal medium.

Corium is the substrate of the connective tissue of skin, makes skin have structural strength, can protect health injury-free, store moisture, and interact with epidermis, the shape profile of dermal papilla reflection epidermis is promptly at the alternative skin ridge and the Pi Gu of below the epidermis.

Skin is the organ that complete function is arranged, by nerve, blood vessel, hair follicle and the appendages of skin that secreting gland consists of.The various ingredients of skin have different functions, comprise that the protection health is not subjected to extraneous infringement, stop loss of moist, absorb and block radiation regulate body temperature, sensitization and immunological surveillance.

Blood vessel and lymphatic vessel play an important role in skin, and nutrition can be provided, regulate body temperature and blood pressure, and the kind of skin heart bed depends on the kind of their dabbling skin, type and quantity and the corium and the hypodermic thickness of the appendages of skin.

Cutaneous nerve includes sensation and sympathetic (independently) nerve, the sympathetic nerve motor fiber mixes with Sensory nerve fibre in corium, finally prolong and draw branch in sweat gland, blood vessel and arrectores pilorum, the sensitization fiber be touch, pain with the corpusculum terminal organ of specialization, itch and the receptor of stimulation of physics and chemistry, and the major part of human sensory cortex is from the skin reception sensory information of face and hands.

Secreting gland is the appendages of skin, comprises apocrine secretion gland, exocrine gland, mixed gland, buccal glands and sebaceous gland.Various types of bodies of gland have its unique morphological characteristics and function.All these appendages of skin are all from embryo's epidermis.

Hair is compound keratin circular cone thing, the cortex scale ring-type surround that wherein has squama closely to cover, and hair can be divided into (1) hair: thin, no myelin, non-pigment, shorter; (2) terminal hair: thick, longer, pigment is arranged mostly, myelin is arranged.Also have the hair of intermediateness, the hair of all fetuses all claims fetal hair.

Hair follicle is main epidermal appendages, and it and epidermis are all derived from same embryo source, are positioned at the surface of skin, and hair follicle is that an and inner root sheath (IRS) adjacent with epidermis and hair shaft itself are formed by an external root sheath (ORS).The cell that is in the division actively can produce inner root sheath and hair shaft, is called stromal cell.The Interstitial cell bag of specialization being arranged in follicle bulb, be called dermal papilla, is the epithelial cell in the cambic division of a group.

The hypomere of adult's hair follicle experience active trophophase (anagen) and period of destruction (catagen/telogen).Along with exhausting of the multiplication capacity of stromal cell, hair follicle is degenerated, and drags dermal papilla the nonvolatil epithelium of hair follicle partly to call knuckle, and knuckle is considered to the family of known hair follicle stem cells.Receive the stimulation that dermal papilla spreads out of, in the knuckle one or each cell are as the renewable hair follicle of reaction.

Subcutaneous tissue also claims the fat layer, one deck fat is arranged, the major function of skin histology is an attemperation, the buffer mechanism wound, keep physical shapes, packing space, most important then is as standby energy source, subcutaneous tissue comprises that three layers of fat deposit are separated them by connective tissue sheath (mesh skin retinocula cutis).

Corium is divided into mastoid process layer and lamina reticularis, and the former profile is the same with epidermis, and the latter extends to subcutaneous tissue from the mastoid process bottom, and dermal papilla contains a lot of III Collagen Type VIs, and these collagens are by the very little fibrous little fibre bundle of radius (width 1-10 μ m).Lamina reticularis corium mainly is made up of type i collagen, and this class collagen is made into big fibre bundle (width is greater than 40 μ m) by large diameter fiber.

At microscopically, collagenous fiber bundle is arranged in orthohormbic structure, that is, every layer all becomes positive angle with its last layer with following one deck.

The histological characteristic of the fetus wound healing of no cicatrix is the regeneration of muscle around reaching in the corium adnexa.But people generally believe, the adult of degree of depth part corium burn or full pachydermia layer burn, and healing can only be the regeneration of cicatrix, and the structure of adnexa and function also are subjected to substantial loss.

It is the destruction of normal configuration outward appearance that skin generates cicatrix, because the change of skin texture, color, vascularity, neural supply, reflectance, biochemical characteristic, healing position or raised or sunken [referring to (1996) Plast such as Ferguson, Reconstru Surg 97:854] have been caused.From the histology aspect, cicatrix is the change of tissue microstructure, and its collagen deposition and group row are different from unmarred tissue on every side.

The exogenous growth factor is used for the wound part, under lab can improves the speed of wound repair.But in the therapy of the wound location application exogenous growth factor, it is not fully up to expectations to be proved effect clinically.TGF-β can not improve wound healing, and the PDGF-BB that has obtained FDA approval listing is only to chronic wounds more mouth benefit a little.More disappointed is that this point point benefit also is under the situation of unloading under thorough debridement and the weight, is operated just and can be obtained by veteran doctor.

The environment of the chronic trauma of human body can not duplicate in laboratory animal, and the clinician wants with ectogenic growth factor for treating wound, but is faced with and the transmission relevant various challenges of protein to human body.The exogenous growth factor of for example adding can be destroyed by protein resolvase and oxidant soon, and another challenge is that the fibroblast in the chronic wounds does not often react somatomedin.

Described in the part of this explanation back, the invention provides a kind of method of innovation, make animal particularly human body cultivate the reproducibility stem cell by original position in vivo and finish tissue repair or neomorph.For example, degree of depth large-area burns are by the skin of inducing again tissue regeneration promoting of original position adult stem cell, and this development of stem cells becomes embryonic cuticle stem cell and other required tissue stem cells of various regeneration skin.Regenerated skin keeps normal 26S Proteasome Structure and Function and has a complete set of adnexa, and the clinical achievement of these " miraculously " shows that methodology of the present invention can be used for various tissues and the organ of regenerating.

On the one hand, method of the present invention can be used for physiological ground and repair the skin of damage and preventing from scar, as deep ii degree burn (or part corium burn), stratum basale is destroyed, corium also is badly damaged, also in the skin survival, but this method also can be used to the skin of regenerating to a part of corium, repairs the 26S Proteasome Structure and Function of epidermis, corium and the various appendages of skin.For example, patient's epidermis and corium are all by fire burn or chemical burn, and promptly shallow III degree or full pachydermia layer burn can adopt this method treatment, and healing skin comprises that the physiological function of adnexa does not all have substantive forfeiture.

In addition, method of the present invention can be used for the regenerating wound of other types includes but not limited to wound, surgical wound and infects wound; Ulcer in body surface includes but are not limited to chronic ulcer, diabetic ulcer, decubitus ulcer and lower limb vascular disease and other are because the not wound healing mouth that thrombosis causes; The wound and/or the erosion that are caused by antibacterial or viral infection are as vaginitis, cervical erosion, gingivitis; Because the wound that venectasia and/or expansion cause is as hemorrhoid; The cold injury and the chapped skin that cause by wind and cold.Adopt compositions provided by the invention, but the equal physiological of these wounds heals and does not have deformity or maimed person.

In order to realize these functional result on skin, the present composition is used for the original position of injured skin, the particular group of cytoadherence and reproducibility tissue by activating and regenerating stem cell, particular organization, generation therapeutical effect.

The reproducibility skin progenitor cell can be present in the survival tissue of skin, and for example injured skin can obtain by the epidermal stem cells that activation is in stratum basale repairing, and the present composition can and not form cicatrix in order to the physiological healing of the epidermis that promotes damage.

In addition, the present composition can be used as cosmetics, improves skin beauty.For example, by transmission medium such as the liposome or the oil of chemistry, or the method for physics such as ultrasound-transmissive, said composition is imported basal layer.For because inside or external factor such as acne, irregular skin surface and/or color exception that black spots and wrinkle caused, available chemical method (for example glycolic or enzyme) or physical method (heat or luminous energy) are removed part or whole skin surface, then the present composition is used to have the skin of survival corium, reproducibility stem cell in other tissue of the epidermal stem cells of remaining basal layer or skin can be activated, promote skin regeneration, make skin look younger, and do not produce cicatrix.

For example, at various skin histologies, can be stimulated as the reproducibility stem cell in the hair follicle.The data of a series of laboratory animals and human body shows, the hair follicle knuckle is the gathering ground of epidermis and hair follicle stem cells, the knuckle cell has very long pericellular [Morris Potten (1994) Cell Prolif 27:279-289], and can turn out best hair follicle horn cell (Yang[1993] J.Invest Dermatol 101:652-659) in culture medium.Other tissue of skin, also assembling as blood vessel and exocrine gland has the reproducibility stem cell, and they can be activated and break up becomes various reparation skins and the required cell of regeneration epidermis.

All damage and/or lose the skin of function fully for corium and epidermis, the present composition can be in order to activate or to induce reproducibility stem cell in the subcutaneous tissue such as the Interstitial cell in the soft tissue.

When whole ingredients of skin, promptly during the destroyed fully and/or loss function of epidermis, corium, subcutaneous tissue, the present composition can be used for activating the reproducibility stem cell that comes in the connective tissue of Musclar layer and the interstital stem cell in the bone marrow.

Must be pointed out that method and composition of the present invention also can be used for promoting the anti-differentiation of cell, that is: the cell of differentiation is changed into adult stem cell, then, participate in the process of tissue repair and neomorph as the reproducibility stem cell.

B) the homeostatic balance of recovery organization is with prevention and treatment cancer

The method that the present invention describes can be used for prevention and treats various cancers, and cancer is regarded as in the cell usually and the homeostasis between the cell is regulated the result who gets muddled, in case homeostatic balance has lost, malignant change will take place.The degraded of the factor of microenvironment such as substrate constituent, and the interaction between host and tumor all is the indispensable condition of malignant cell existence and growth.

The present invention shows, adopts the compositions and methods of the invention, and in-house homeostatic balance can be recovered, and can not lose physiological function.The present composition can be regulated the information exchange between the cell, by stimulating the crosstalk of various cell membrane proteins such as connexin and Cadherin mediation, the adjusting that the result makes growth, differentiation, apoptosis and the migration of cell obtain coordinating.

Compositions of the present invention can be by promoting host cell and precancer cell or cancerous cell the growth at abutment, gap and the homeostatic balance of recovery organization, the abutment, gap is the joint between a kind of cell of specific type, has in most of zooblast.Two adjacent cell interactions are undertaken by the cell membrane protein connexin.Connexin forms the abutment, gap, and 6 identical connexins form a connexin, and two continuous gaps that stride across cell of connexin form successive aquaporin, and two cells are coupled together.Each abutment, gap is the combining of cytoplasm fracture of particle and serous coat in the uniform film of cluster.Particle is corresponding to a connexin in each film, and the abutment, gap makes the micromolecule between the cell, and passage can be arranged, and is relevant with various life processes such as growth, cellular metabolism and cell Growth Control.

Most of connexin shifts the back by phosphorylation, mainly be to act on the aminoacid positions such as serine, connexin is the kinase whose target of range protein, wherein some enzyme is confirmed, be protein kinase C, former activated protein kinase of mitogenesis and v-Src enzyme propylhomoserin protein kinase.Phosphorylation is relevant with the adjusting of many connection procedures, as the control that exchanges, makes up/be snapped away from, degraded and gap engage passage.

In addition, another kind of epicyte protein Cadherin also pair cell and cytoadherence and migration plays an important role, the cell of Cadherin mediation and the adhesion effect of cell are interfered in the cell of protein enzyme propylhomoserin kinases (PTK) distortion, and Cadherin itself then is not the good culture medium of PTK; Their Cytoplasm binding partners Armcatenins but is the good substrate of PTK, therefore, can be used as the good candidate that the disease of the Caderin behavior brought out of mediation PTK becomes.For example β-catenin combines with the Cytoplasm district of classical cadherin, and can regulate sorption also/or as the bridge of cadherin and myofibre protein leukocyte skeleton.

The present composition can activate these kinases probably, and these kinases are the cell binding partners of connexin and Cadherin the Caterins phosphorylation then.By the adhesion effect of these proteinic phosphorylations and cell and cell, the information exchanging channel between tumor cell and the host cell is repaired.After repairing being connected of tumor and host, tumor cell has been subjected to host's regulation and control, under host's regulation and control, apoptosis (programme controlled cell death) can take place in tumor cell, or differentiation becomes non-oncogenic cell, like this, the homeostatic balance of tissue is restored, and can prevent or suppress cancerating of tumor.

On the one hand, method of the present invention can have influence on epithelial cell such as psoriasis or other dermatosiss of skin in order to the disease or the canceration in early stage of treatment or prevention hyperplasia, comprises the dermatosis that hyperplasia, canceration in early stage or ultraviolet bring out.

Method of the present invention and then the probability that also can be used for preventing skin carcinoma or reduce the skin carcinoma development, and reduce because the order of severity of the photoaging that causes sunshine.

On the other hand, method of the present invention can be used for treatment and prevention hyperplasia disease or canceration in early stage, it has influenced internal's epithelial cell such as gastrointestinal tract organ, oral compositions of the present invention or local injection can recover the internal medium stable equilibrium of these organs, are reconstituted in the cell and the intercellular crosstalk of early stage cancerous tumor cell and host health cell.

In addition, method of the present invention also can be used for the treatment of upper and lower gastrointestinal cancer, upper gastrointestinal cancer for example, include but are not limited to (1) by excessive use ethanol, alkali take in, relax can not, smoking, contact nitramine compounds Barrett ' s mucosa, callus forms, mycotoxin, the infection of changeable viruses such as the esophageal carcinoma that human papillomavirus (HPV), herpes simplex virus (HSV), cytomegalovirus (CMV) and general civilian two syndromes of Epson-Barr virus (EBV) etc. cause; (2) because the gastric cancer that achlorhydria, helicobacter pylori infection, the stomach resecting operation in past and BillrothII operation cause; (3) cancer of pancreas that causes by smoking, contact beta-naphthylamine, benzidine and chronic pancreatitis; (4) hepatocarcinoma that causes by hepatitis B virus, chronic hepatopathy such as chronic active hepatitis and hepatitis interstitialis chronica, contact mycotoxin, ionizing radiation, steroid hormone and hardening thing, and (5) are owing to hardening bile duct class, the cancer of biliary duct that parasitic infection and steroid hormone cause.Cancer in the following gastrointestinal comprises colorectal cancer such as colorectal carcinoma, constitutional lymphoma, melanoma, big enterosarcoma.Adenocarcinoma accounts for more than 90% of colorectal cancer, and carcinoid tumor accounts for the major part of other above tumor of colorectum.

C) prevention and treatment gastroenteropathy

The present composition and method can be in order to activating or to induce the reproducibility stem cell in the stomach intestinal tissue, with the damage and the illness of the mucosa of repairing the organ in gastrointestinal tract.

In the liner of small intestinal, cell is arranged in the epithelial tissue of monolayer, and this epithelial tissue covers the epidermis of fine hair and gives prominence to goldbeater's skin.Goblet cell slimy is dispersed in the adsorptivity brush border cell of epithelial tissue, epithelial tissue is also serving as a contrast crypts, these crypts stretch to following connective tissue downwards, each crypts is made up of 250 epithelial cells, comprising epithelial stem cell, these multi-functional stem cell are positioned near bottom or its [referring to Loeffleretal (1993) the J.Theer Biol 160:471-491] of crypts.Gut epithelial stem cells can be reacted to the existence of a matter or the instruction of differentiation.Under normal circumstances, these cell cycle cycles are slow, the spitting image of hair follicle stem cells, wherein some changes fast but proliferative cell temporarily, they move to the stage casing, be divided into the enteroendocrine cell of absorbefacient brush border enterocyte or goblet cell slimy or fine hair subsequently, in order to keep homeostatic balance, the cell that has broken up is dead subsequently and come off from fine hair and to enter enteric cavity.

Relevant therewith, compositions provided by the invention can be treated the human body alimentary canal illness, use a kind of compositions that is dissolved in the sterol compound in the oil that contains promptly for patient's digestive tract, wherein the percentage by weight of sterol compound content is 0.01%-20%, preferably select edible oil for use, and compositions contains Cera Flava, and the percentage by weight of its content is 1%-20%.

Digestive tract disease may be that gastrointestinal disorders comprises gastric ulcer, intestinal class disease and other damages because human body alimentary canal organ or nutrition channel comprise the damage or disorderly the causing of mouth, esophagus, stomach and intestine and small intestine.

A common reason of gastrointestinal disturbance is a helicobacter pylori infections, these infection can cause the chronic gastritis of activeness and take place frequently related disorders arranged, as duodenal ulcer, gastric ulcer, MALT lymphoma or Menetrier ' s syndrome, elimination or inhibition helicobacter pylori can reduce the recurrence of duodenum and gastric ulcer.

Persistent gastritis is relevant with helicobacter pylori infections, often occurs the characteristics similar in appearance to intestinal on gastric mucosa, and this situation is called intestinal (sample) metaplasia (IM), may be the signal that the gastric cancer risk strengthens, and is second largest because of the lethal disease of cancer in the whole world.

The cause of disease of IM it be unclear that, it may be a kind of adaptation of mutability, or to the defense reaction of helicobacter pylori, someone infers that the mucosa of distortion may produce mucus or other compositionss are created a kind of environment to anti-helicobacter pylori, therefore, helicobacter pylori is generally treated the sickness rate that should reduce gastric cancer.

The inventor thinks that compositions of the present invention can repair the mucosa of damage effectively; in gastrointestinal; regenerated condition particularly is provided under one's belt, and after this compositions of use, medicine mixes with gastric mucosa in gastrointestinal tract; form protecting film; wherein contain mucin, the further stimulation of other compositionss in mucosa and food and the stomach can be separated, in this case; sterol compound in the compositions and other effective ingredient are released the activating and regenerating stem cell, promote mucosa to accelerate to repair.In addition, the present composition also can change the toxicity that suppresses helicobacter pylori effectively by the form that makes antibacterial, and by the gastrointestinal regeneration of health, the ulcer situation that helps helicobacter pylori improves, and suppresses the growth of antibacterial indirectly.

Compositions of the present invention can be used for treating helicobacter pylori and relevant with it disease (as ulcer, gastric cancer, non-ucler dyspepsia, gastritis and esophagel disease stomach function regulating-esophageal reflux disease).It is because it has overall protective effect to gastrointestinal tract that this compositions can be used for treating these diseases, and it can also promote the maintenance of mucosa integrity.

Said composition can be used to suppress helicobacter pylori sorption or formation bacterium colony on the mucosa, can be used for promoting the healing of the damaged tissue relevant with helicobacter pylori infections, at this on the one hand, it is important that this compositions will be added on the impaired monolayer of enterocyte of fusion, to activate epithelial stem cell in the crypts, increase the speed that epithelial cell moves into wound.

Can be used to protect gastrointestinal tract or nutrition channel as intestinal as this compositions, it also can be used for protecting oral cavity and esophagus to avoid the damage that causes because of radiation and chemotherapy.

This compositions also can be used to protection and/or treats usually by ethanol or drug induced damage.

D) promote natural on-off cycles of hair growth and treat alopecia

The present composition also can be used for promoting hair growth or recovers hair follicle and the physiological function of tissue on every side such as blood vessel, sebaceous gland.

Hair is thread cutin structure, is formed by epidermal derived, and hair is divided into two big classes: hair, characteristics be short, narrow, be covered in most of body surface; Terminal hair is characterized in thick,, long, often pigment is darker.Terminal hair comprises axillary fossa and the hair of phalanx, most male face and hair on one's body after scalp, eyebrow, eyelashes, the adolescence.

Every hair is made up of hair shaft and root, hair shaft then is made up of special horn cell, Rhizoma Imperatae is arranged in hair follicle, can be deep into subcutaneous tissue or at the shallow table of corium place, hair follicle is because external root sheath (ORS) that epidermis links to each other and inner root sheath (IRS) composition, enliven splitted cell and generate inner root sheath and hair shaft, be called stromal cell.The near-end expansion of root forms ball top, make it recessed by table mastoid process on the tapered tubular and deeply feel, ball top has comprised the substrate and the male character types in Chinese operas, usu. referring tov the bearded character district of bud, and the Interstitial cell bag of a specialization is arranged in the ball top, be called dermal papilla, be the epithelial cell in the temporary division of a group.The multi-functional cell of this group covers the epidermis mastoid process, has the splitted ability of silk, can produce hair and inner root sheath on every side thereof.The cell that mitosis produces moves on the top, along several different approach differentiation.

Hypomere in adult's hair follicle, the experience active growth phase (anagen) and period of destruction (catagen/telogen).Along with the multiplication capacity of stromal cell exhausts, hair follicle is degenerated, and the cell bags of dermal papilla is dragged to nonvolatil follicular epithelium position, is called knuckle.Knuckle is considered to the family of known hair follicle stem cells.Stimulation to dermal papilla is reacted, and the stem cell regenerating of one or more knuckles becomes hair follicle.

The growth of hair follicle depends on a series of information transmission between corium and the epidermis.In embryonic development period, because the interaction between an epidermis and the matter forms hair follicle.The corium assembly of hair follicle (being dermal papilla and dermal sheath) is derived from a group Interstitial cell.The startup of hair follicle and growth come from the gathering that corium is given birth to the horn cell of fibrocyte and epidermis.Epidermal cell proliferation, being penetrated into becomes stopper in the corium, and subsequently, the deutero-cell of epidermis surrounds the aggregation of corium, and it is introduced in the tissue bag, promptly in the dermal papilla.It is generally acknowledged hair follicle and dermal papilla, form when being embryo growth, obviously do not grow in puerperal.

Hair growth is subjected to the influence of the propagation of hair follicle stromal cell, three differences is arranged by stages: regeneration period hair active growth; The catagen hair follicle is active to descend; Resting stage, cell was no longer bred.In typical people's scalp, regeneration period can continue several years, and catagen has only several weeks, then arranged [referring to Bertolino etal (1993) " Bialogy of HairFolicle " in Dermatology in General Medicine the several months resting stage, pp.289-93.Fitzpatrick et al., eds.McGraw-Hill].This upgrades circulation time according to different parts in animal species and the animal and different.After resting stage, alopecia, in another cycle, different interim epidermis, corium and the pendant and terminal fatty chains of hair growth also changing.And terminal hair generates with melanocyte in regeneration period, because the melanocyte in the hair follicle produces melanocyte, enters [referring to Denileako etal 1996 Mol.Med Today 2:460-67] in the hair shaft.

These cycles are subjected to influence of various factors.For example: different somatomedin, as steroid hormone, the interaction of corium-epidermis, the vascularity of corium, neural, the ectoderm factor and immune system all participate [referring to Stern etal (1996) Dermatol Clin 14:167-96 and lindler etal (1997) Am.J.Pathal 151:1601-17].

Alopecia is divided into several, and reason is different.Bald head is positioned at the crown and the front portion is very common android type bald head, and it is alopecia totalis that bald head also can involve whole head.Different alopecias is divided into (1) alopecia totalis: all scalps do not have hair, i.e. scalp alopecia totalis but the hair at other positions of health is normal; (2) alopecia universalis: be not only scalp, and whole health does not have hair; (3) alopecia areata: be alopecia localis, concerning the women, alopecia usually occurs in after the fertility child or cuts out after the contraceptive; (4) alopecia that causes of chemotherapy, temporary often; (5) alopecia that causes of radiotherapy is nonvolatil often, because the damage of irreversibility has taken place in the hair follicle raying; (6) male pattern alopecia (also claiming bald) is common male baldness, is positioned at front portion, the crown and top, is that inherited genetic factors causes.

Bald hair is mammiferous natural process, and is especially very common among the man in health adult, and alopecia also can be caused (as anticancer chemotherapy) by the factor of chemistry and physics, also may be owing to age growth and some special disease cause.Typical alopecia is that hair follicle is gone into resting stage from regeneration period very F.F. because the disorder of hair update cycle at first is that period frequency is accelerated.Under the normal condition, nearly 150,000 hairs on the number of people, about 10% is to be in resting stage.Bald hair on skin, obviously be that more hair follicle is to be in resting stage, last hair follicle is degenerated, and this process shows as hair and constantly attenuates, this is first mass change (be fine hair many and terminal hair is few) of hair, and the quantity of last hair in this skin region reduces.

Except alopecia, it is overweight also to have abnormal hair growth under the situation of only a few, as depend on unduly women's hirsutism that androgen causes sick and with irrelevant hirsutism (Bertolino etc. (1993) " Disordersof Eidermal 35 Appendages and related disorders " the in Dematology in General Medicine of androgen, pp671-95, chief editors such as Fitzpatrick, McGraw-Hill, this situation can produce far-reaching societal consequence concerning patient individual.

Alopecia, hirsutism and other hair growth disorders are very general, develop effective cosmetics and the clinical treatment agent has very big meaning.But, although this demand is arranged, effectively prevent and the method for the treatment of still very scarce, for example can not obtain the effective treatment, as available hair grafting operation to many alopecia patients (as the patient that accepts chemotherapy and old people etc.).But what surgical operation was maximum also is the part of Therapeutic Method, and electricity irritation once was proposed and is used for promoting hair growth (seeing US Patent No 5,800,477 and the document of wherein quoting), but the curative effect of these methods still has problem.

E) regeneration of tissue repair and other organs

Compositions of the present invention also can be used for other organs of repair tissue or regeneration health by cultivating the reproducibility stem cell with original position in the body, comprises being not limited only to heart, kidney, lung, liver, pancreas, eye, brain, tremulous pulse, nerve and bone.For example but this compositions local injection is in cardiac muscle, with direct activation/the induce adult stem cell (ASCs) of heart, and treating various heart diseases and cardiovascular diseases, and the heart of behind heart attack, regenerating.Said composition also can be applied topically to liver, to activate/to induce liver stem cells, make owing to different reasons, as the too much and impaired liver of drinking is repaired.Described compositions can also be used for pulmonary with regeneration tissue wherein, as alveolar.

This compositions also can be used for repairing impaired glomerule and other cause the bead disease of chronic renal failure.In kidney, little spherical structure very little (diameter 100-200 μ m) is dispersed in the renal cortex (3 * 10 ⁴-1 * 10 ⁶Bead/kidney), therefore, conventional method such as grafting are difficult to find rake, and this compositions of direct injection can fully stimulate bead, to activate/to induce reproducibility stem cell wherein.

In addition, this compositions and method are by activating or the regeneration induction stem cell, can treat other because loss or reduce the illness that renewable cell mass causes, comprise hematopathy and relate to damnification of immunity function or the disease of loss, also can be used for stimulating the growth of noble cells, and keep the physiological equilibrium, comprise that existing noble cells continues to express its phenotype, and aged phenotype reverse is young phenotype.This is particularly useful for the treated tissue illness, and promptly because metabolic function goes down or lose, cell ageing or static and lose the disease of function as aged cells and/or osteoporosis and neurodegenerative disease, comprises degenerative brain disorder.

2, the mechanism of action of cell of this compositions and molecule

The invention provides a kind of novel compositions and method with the repair tissue and the organ of regenerating, current main school's thought thinks that tissue regeneration completely can only realizing from body skin or heterodermic graft by vitro recombination.Basic conception of the present invention is thought an adult who grows fully just in time in contrast, and tissue that it is badly damaged and/or organ have instinct, in the environment that can be suitable intrinsic or external signal are reacted, and realize self-regeneration and neomorph.This regenerative environ-ment must have the compositions of external source to support, does not substantially lose physiological structure and function to promote neomorph.Use the present composition in vivo and original position create a kind of environment, organ is regenerated naturally according to embryo development procedure, recover its physiological structure and function.

The inventor thinks cell as the least unit of life, and its activity plays pivotal role in physiological tissue repair and neomorph process.Although many somatomedin have all participated in this process, but finally must integrally regulate cytoactive, could obtain homeostatic balance regeneration, tissue repair and neomorph may cause the incomplete recovery of physiological structure and function only by adjustment signal or some somatomedin.Because being health, the meticulous balance of life keeps by the complicated activity of oneself regulating its cell, rather than only control by some somatomedin.

As previously mentioned, the inventor has disclosed in adult tissue and has repaired and neomorph, as ultimate principle to the reaction of endogenic and ectogenic signal, under regeneration condition, adopt method of the present invention, in carrying out the regenerated organ of nature, can observe the reaction and the intercellular interaction of the novelty of cell.These phenomenons also only when using the present composition, just can be observed, and for example, deep ii degree burn all is that the cicatrix healing is arranged in matched group or in conventional SD-Ag (silver sulfadiazine) treatment group.Then need make skin graft to shallow III degree burn.With the wound surface of traditional method treatment, the interaction between cell and tissue is confusing, and the back skin that causes healing has lopsided cicatrix, maimed person and dysfunction.For adult tissue and the organ that makes damage can recover normal physiological structure and function, must apply ectogenic compositions in this position, so that regenerative environ-ment to be provided, regulate the cell activity that reaches original position in vivo.

Each composition of this compositions is brought into play its effect separately in regenerative process.The inventor does not wish to be retrained by theory, and the mechanism of action that proposes rational molecule and cellular level in the present invention is based on the difference that (1) understands fetal development and the wound healing process between embryo and adult; (2) physics of effective ingredient, chemistry and pharmacokinetic properties; (3) this compositions is regulated down, the clinical preceding and clinical observation of cell growth, tissue repair and neomorph.

1) human embryo grows

Human the same with the animals and plants of other each cells, be a kind of clone of orderly cell, contain identical chromosome set, but the approach difference of specialization, though last structure may be very complicated, people's life is that cell growth, division and dead technical ability are generated by these limited cellular activities.Human body cell is by starting and closing the synthetic of specific proteins and break up, human chromosome group intrinsic program is controlled this process, and be subjected to the influence of varying environment factor, cell to produce the adjacent cell of molecular signal influence, and the signal that flanking cell transmits is reacted.It has been generally acknowledged that in each cell identical multiple chromosome set is determining the rule of cell to the reaction of different stimulated, and guide complicated each cells whose development process.By this growth course, fetal development becomes adult's organ.

Germ cell is a maxicell, and constantly carrying out mitosis becomes many minicells and be called blastomere, and its gross mass does not become.This process is called egg cell division.In this stage D NA self-control and mitosis is high-speed, and splitted embryo depends on that almost completely RNA, protein, film and other compositionss lay in ovum.After division stage, cell division speed slows down, the embryo chromosome group transcribe beginning, this variation is called the blastaea middle transition.During beginning, embryonic cell is not only mechanically and is combined, and by combining by ion and micromolecular gap junction point, these characteristics can be transmitted information very effectively, help the mutual coordination of cell behavior, simultaneously closely be connected to form a seal area between the blastomere of embryo's ragged edge, embryo's inside and foreign medium separated, greatly about 16 cell stages, Na ⁺Begin to pass cell membrane and enter embryo inside, so intercellular space is because formed infiltration area gradient moisture also along with entering.As a result, intercellular crack is enlarged in the embryo depths form cavity, be called blister cavities, in this stage, the embryo is called blastaea.

The outer field cell that constitutes blastaea becomes an epithelial layer, and the coordination exercise that forms for gastrula provides stage, and this theatrical process changes simple cell sky ball into the structure of each layer.That the multiple structure of blastaea divides is inside and outside, in three layers, central intestinal tube is involved in inside to the okioplast of body early embryo and forms the internal layer of blastaea.

Because of the three-decker that form gastrula, penetralia is original intestinal tube, is entoderm; Outermost is outside epithelium, is ectoderm; By a loose organized layer that forms by Interstitial cell, be mesoderm between this is two-layer, embryo's this three-decker, the intestinal that is equivalent to substantially be grown up is in inside, epidermis externally, and connective tissue and muscle are in intermediary structure.

What mammal embryo was grown is highly to regulate and control in early days, and the destiny of each cell is all decided by the interaction of itself and flanking cell.When the environment of growing was undesired, embryonic cell was out of hand.When for example normal early stage mice embryonic was transplanted in the kidney of adult mice or the testis, its composition was disorderly soon.Normal cell proliferation interrupts, and the result is a kind of fantastic thing growth, is called teratoma.Teratoma is the cell of a group disorder, comprises various differentiated tissues, and as the epithelium of skin, bone, gland, the cell of these differentiation and undifferentiated stem cell mix, and continues division and generates more differentiated tissues.

The signal that embryonic stem cell can conform very much makes one's options in different differentiation pathway to instruct them.In suitable environment, embryonic stem cell can start or close the growth clock---order about cell from the process of embryo to ripe attitude development, the stem cell of similar performance for example, can culture medium, derive from normal internal layer cell mass, cell just spread out after they bred, in case disperse, some cell can continue unconfined division and not change its characteristic in suitable environment, and the stem line that is generated can unconfined division and do not break up.Protein growth factor in the culture medium or cytokine are that the existence of leukaemia inhibitory factor (LIF) is vital [(1998) Genes Dev 12 such as Nichols etc. (1998) Cell 95:379-39 and Niwa: to 12:2048-2060] to these growth courses.After LIF removed, embryonic stem cell in the culture medium is promptly assembled the compositions that becomes the class embryo automatically, can break up becomes many cell lineages, comprises pulsatile heart myocyte, blood island, neuron, pigment cell, macrophage, epithelial cell and gives birth to adipose cell [Bradley (1990) Curr.Opin.Cell Biol.2:1013-1017].But it is confusing starting these development programs.That generate then is miscellaneous tissue " hundred precious capsules " (Fuchs etc. (2000) Cell100:143-155)

This in culture medium, unordered uncontrollable embryonic stem cell ectogenesis is attempted the external regeneration organ to some, and transplant then and give patient to recover the people of physiological structure and function, be a kind of challenge.Will be from embryonic stem cell at reconstruction in vitro function organ completely, it is a challenge greatly, be exactly will be from the ambient signal as " milky way ", pick out the signal of " constellation ", can optionally " induce " embryonic stem cell to abandon all other approach, and move towards the development pathway of particular lineage.Once attempted in all sorts of ways and produced the cell of the specific type of " pure " from embryonic stem cell, for example can express neuroglia predecessor's sign, pure multi-functional ancester cell group can obtain [Brustle etc. (1999) Science 285:754-756] from mouse embryo stem cell.Whole process is aborative, and the embryonic stem cell aggregation of cultivation is bred in culture medium continuously.(1) at first only contains fibroblast growth factor (FGF2) on the culture medium; (2) be that FGF2 mixes with epidermal growth factor (EGF) then; (3) be that FGF2 mixes with platelet derived growth factor (PDGF) at last.As a result, these multi-functional stem cell use " designer's cocktail " to contain the mixed liquid dipping of multiple somatomedin, can keep in culture medium many generations.Can produce the cell mass of pure specific a kind of types of organization,, not reach the target of external regeneration organ though these achievements are remarkable and unordered.The cell mass that must recognize single type is not a tissue.Rebuild physiological living tissue cells, need two types cell at least, these cells must can pass through the intercellular signal pathway, intersect talk in physiological environment.Although used " cocktail " of somatomedin furnishing to do a lot of work, under the situation of all suitable physiological environments, to not fail probably before these signal deciphers and also at the multiple functional organ of reconstruction in vitro as health oneself.

In contrast, the present invention shows clinical, and the human organ that is badly damaged can be in vivo and in-situ regeneration, and need not to transplant.Be to adopt an important contribution factor of the compositions and methods of the invention to be, adult stem is induced and is bred so that various types of reproducibility cells to be provided, building various tissues again,, rather than move on to external because these reproducibility cells in vivo and growth in situ.The gene program of just having set when fetal development is followed in their growth and differentiation.But these reproducibility adult stems are to be among, the rugged environment diverse with fetus, and the destiny of these stem cell is controlled by intrinsic regulation mechanism not only, also is subjected to external interference, as bacterial infection and air pollutants etc.Therefore, must provide external compositions to promote the breeding of adult stem, generate the required histiocyte of a large amount of regeneration, and the differentiation of adult stem should be regulated and control by an environment favourable, the simulation fetal development, interaction between the cell of identical or different type also should be regulated and control, to promote the recurrence and the adhesion of tissue specificity.Like this, the interaction between tissue can promote regenerated tissue to make up according to the specificity of organ, becomes function organ in vivo.

Adopt the burned skin healing as adult neomorph model, the inventor has tested the present composition to the growth of stem cell and the influence of differentiation, and to special cell-cell, the interaction between cell-tissue and tissue-tissue.In addition, these effects of this compositions also in external model, have been observed.

2) epidermal stem cells

The cell that will replacement itself can splittedly not break up just needs stem cell, at the cell of the outermost layer (epidermis) of skin, has broken up finally, can not divide to replenish dead keratinocyte again.Epidermal stem cells is positioned at basal layer, and the junction of epidermis and corium can constantly divide the generation daughter cell, and differentiation becomes various keratinocytes to upgrade skin again.

Epidermis is multiwalled epithelium, mainly formed by keratinocyte, keratinocyte has sp act, the intermediate that can synthesize fibroin is called keratin, keratinocyte is expressed various dissimilar keratin according to the different phase of differentiation, as keratin-1 ,-9 ,-10 and-16, particularly keratin-19 (K-19) be in the basal cell layer of fetus epidermis and the budding knuckle of people embryo hair in [Dale etc. (1985) the J.Cell Biol.101:1257-1269 that finds; Moll etc. (1982) Differentiation 23:170-178; Akiyama etc. (2000) J.Invest Dermatol.114:321-327].The keratinocyte of expressing K-19 has been considered to known epidermal stem cells.

From the keratinocyte of epidermal stem cells differentiation, the outward appearance of its each layer is all different.Substrate plate below innermost layer connects is basal cell, and the energy mitosis generates more epithelial cell; Be which floor bigger barbed cell above the basal cell, their a large amount of desmosomes provide the ground that berths for keratin filament; Be the granular cell layer that approaches outside the cell of spinosity, it has indicated internal layer that metabolism is active and the boundary line between the skin, and skin contains dead cell, and the organelle of this cell all disappears, becomes flat squamous or squama, fills out with vertical close keratin.

When some basal cells divide, when the cell quantity of basal layer was increased, the keratinocyte of other types slipped out basal cell layer, enters barbed cellular layer.When they arrive granular layer, the organelle in nucleus and the endochylema is lost, and is transformed into the squama of the keratinization in the horny layer.At last, these squamas come off from skin surface.Usually cell bears the time that the surface of health comes off from the basal layer of skin by epidermal stem cells, is to differ in 2 weeks to 4 weeks according to region.

In principle, originally epidermal stem cells can generate two kinds is similar daughter cell, but subsequently, environment makes their destiny differences in order to guarantee the supply of new Skin Cell, and the skin table patch that each oneself grows with each passing day new must have " immortality " cell at least in every monobasic cell.Still exist in its offspring skin patch in the far future.According to circumstances, the production of stem cell may increase, for example when place's epidermis patch destroys, injury region is by the epidermal cell repairing of health on every side, and these epidermis cell move and breed, to cover exposed regions, in this process, formed the epidermis patch of a new self renewal, shown that other stem cell produce, to recover damage.

In order to produce more stem cell, the daughter cell of stem cell may also be a stem cell and do not enter road to terminal differentiation.The destiny of these stem cell is decided by situation, and a kind of possible determiner is to contact with the connective tissue of the exposure of substrate plate or wound, loses this contact and then starts terminal differentiation, keeps in touch the potential of then preserving stem cell.Have been found that with cell outside the contacting of substrate, the destiny of pair cell has material impact.If cell keeps suspending and do not sink to bottom the culture dish, they just all stop division and differentiation.But also find that under normal physiological conditions, keratinocyte occupies the Fn Fiberonectin receptor.Cell is stayed in the substrate plate to keep them as stem cell, if receptor is lost or inactivation, then cell just is discharged away from basal layer, confirms that they will break up.Other reasons causes cell to emit from basal layer to cause losing receptor, cell has just been broken up when immaturity.

Between the cell, the physiological interaction between cell and the tissue keeps undifferentiated state even more important for stem cell.Shown as describing the back at this, in the body inner model of stem cell growth and differentiation, adult stem is activated, under a kind of mode of tissue specificity, interact, directionally break up the whole tissues that become skin and comprise various types of cells that adnexa is required.These narrow spectrum interactions are at the degree of depth and large-area burns skin, accept to be observed in the process of wound healing of present composition treatment.Also will mention in external model in the back, if there is not the present composition to promote cell-intercellular suitable interaction, the rat hair follicle just can not carry out clonal propagation, forms skin histology.

3) adult's wound healing

Adult's wound healing is complicated process, the experience three phases: condense, inflammation, breed and reinvent.

At first, originally condensation process relates to contacting of platelet and fibrin and collagen, the deposition of the outstanding layer of fibrin, first stimulation is the most common damage-lead to wound healing, the activation of organizing complement of Ara mediation, this thorn is goaded segmented granulocyte into action and is attracted to damage field, as a kind of defence to infecting.If blood vessel has broken when damage, SE collagen protein is exposed to platelet, and the result has started clotting mechanism.The platelet that is activated begins to discharge biochemical amboceptor and causes vasoconstriction, loses blood thereby reduce.Platelet also interacts with damaged tissues, causes that thrombin discharges, and makes soluble circulation Fibrinogen be converted into fibrin, constitutes catcher successively and activates platelet, finally forms whole hemostasis " embolus ".When these activated platelet threshings, various cytokine of their α-particle release and somatomedin, they are that inflammatory cell such as neutrophilic leukocyte, monocytic chemistry widely draw agent (chemotaxis), with the mitogen that acts on non-inflammatory cell fibroblast and endotheliocyte, they are related to following wound healing.Fibrin clot can breed and move on it and by its these cell also as support.In addition, the adjusting of the extracellular matrix (ECM) of the synthetic needs of the platelet participation wound healing that is activated, for example cytokine and the somatomedin by secretion of platelet comprises platelet derivation somatomedin (PDGF), transforming growth factor ₁And β ₂(TGF-β ₁With TGF-β ₂), platelet derivation epithelium growth factor (PDEGF), platelet activating factor (PAF), insulin-like growth factor-i (IGF-1), Fibronectin, 5-hydroxy tryptamine.

The second, within the inflammatory phase starts from condensing several hours that start.This process be one to infecting the bridge between opposing and regenerative cell and the damaged tissue.During this period, inflammatory cell attracted to damage field and activates.In the latter stage of condensing (or hemostasis), in case stopped bleeding, the thing followed is exactly that blood vessel expansion and capillary permeability increase.

Acutely inflamed feature, neutrophilic leukocyte, macrophage moves to wound then.These inflammatory cells are engulfed antibacterial and are removed damaged tissue.It is chronic inflammatory disease that development is gone down, there lymphocyte and monocyte infiltration wound.Change macrophage then into, its be considered to be grown up main coordinating factor of wound healing.

The antibacterial and the digestion fibrin matrix of contaminated wound engulfed in neutrophilic leukocyte, for new organization is prepared.They also secrete vasodilation meson and cytokine, and they activate fibroblast and keratinocyte, and macrophage attracting is arrived damage location.The potential pathogen of macrophage phagocytic, remove wound, secretory cell element alive and somatomedin are as fibroblast growth factor (FGF), epithelium growth factor (EGF), VEGF (VEGF), tumor necrosis factor (TNF-a), interleukin-1 (IL-1) and interferon-gamma (IFN-γ).These chemical signals also stimulate infiltration, the propagation of fibroblast and endotheliocyte and move, and cause angiogenesis.

Subsequently, fibroblast enters the fibrous matrix that wound will exist already and replaces with glucosamine and Dan Baijutang.Extracellular matrix in the healing (ECM) contains many glycoproteins equally, comprises fiber synthetic chemical and tenascin.The fiber synthetic chemical promotes zymolyte to adhere to, and tenascin promotes moving of zymolyte by antagonism fiber synthetic chemical.

Further, fibroblast and endotheliocyte are converted into peroxide with dissolved oxygen molecule, and this also promotes further that to the oxygen signal that has that sends the generation of somatomedin is important to resisting wound infection.

The 3rd, in the ensuing date, diversified cell is strengthening propagation and is moving to wound, comprises the endotheliocyte of macrophage, lymphocyte, fibroblast, epithelial cell (being keratinocyte) and formation blood vessel.In migration and breeding, the wound that these cells are added in the healing experiences mitosis fast, becomes the structure of the cicatrix of final typing.

During this period, a process that is referred to as epithelization occurs, and makes edge of wound epithelization again.During the epithelization process, one is epithelium covering beginning migration of main formation with the keratinocyte, and experiences stratification and break up the barrier function of rebuilding epidermis.This process also promotes the expression and the release by somatomedin (as keratinocyte growth factor) of generation, somatomedin and the cytokine of extracellular matrix (ECM) to generate blood vessel.Keratinocyte promotes vascularization by being released into fibroblast growth factor (FGF) and VEGF (VEGF).

They also secrete the TGF-α of performance chemical attraction and mitosis effect, and relate to the PDGF that matrix generates.Fibroblastic further migration and propagation cause collagen deposition to replace Dan Baijutang.In addition, the propagation of endotheliocyte has been set up neovascularization, i.e. vascularization.

In case the monolayer keratinocyte has covered wound surface, propagation and synthetic movable the deceleration, migration stops, and sets up a new layering epidermis that has basic thin layer under the help of differentiation and stratification.

Though cicatrix began to form in this stage.But the contraction of bottom connective tissue helps the formation of new epidermis.Connective tissue makes the wound sealing together by the edge of wound is moved to.When not having to shrink but continue to pile up, connective tissue just forms bigger cicatrix.In addition, when wound is exposed in the dry air, during cell above the unable support, just formed incrustation.Adult's wound of conventional dryness therapy for treating all is to heal with contracture cicatrix and the serious mode of disfeaturing.

At last, when propagation and migratory movement when beginning to slow down, just reinventing of tissue begun.This stage relates to the synthetic of extracellular protein and Dan Baijutang, and the dissolving of collagen protein and synthetic between balance.Though macrophage and lymphocyte also participate in this process, in propagation with move prevailing cell type and comprise epithelial cell, fibroblast and endotheliocyte.This process depends on characteristic, oxygen content and the somatomedin of effective metabolism matrix.Reinvent can continue several weeks, the time of some months even several years.During this period, fibroblast is the kinetocyte of dominating, because they are relevant with the degree of the deposition of new matrix, the seriality of rebuilding tissue and decision cicatrization.Therefore, growth of fibroblasts and differentiation should be regulated by special, so that prevent their over-drastic collagen deposition activities.

In the process of wound healing, somatomedin is set foot in the comings and goings, if any silk division generation, motogenesis, vascularization, chemotaxis, migration and reconstruction.Especially because TGF-β is directly relevant with fibrosis, so the research that it is done is maximum.It is that cell by many participation inflammatory reaction comprises what platelet, mononuclear cell and macrophage discharged, and is comprised in nearly all stage of healing.It is reported that its effect comprises chemical attraction inflammatory cell, increase collagen deposition, inhibition erosion protoenzyme, regulates extracellular matrix components, the former inhibitive factor of barrier fibers albumen lyase and promote vascularization [referring to (1995) Aesth.Plast.Surg.19:237-241 such as Chang].Eliminate the result's who causes owing to the excessive adjusting that reduces excessive vascularization, inflammatory cell infiltration and other somatomedin influence.

Disappointed is the level that improves TGF-β, might not mean relevant with the improvement of cicatrix quality.The result who uses the TGF-β of external source improves the deposition and the fiber [referring to (1992) Lancer339:213-214 such as Shah] of inflammatory cell and fibroblastic level, collagen.Therefore, the healing aspect that is equilibrated at wound of somatomedin can play crucial effects.

At present, the popular viewpoint in this field is that adult wound healing must be the cicatrix healing, because on one's body the adult, the inflammatory wound healing of " normally " is the quality of sacrificing healing for the danger that reduces infection.As this invention proof, adult's extensive deep burn does not have cicatrix this fact that heals, and this doctrine has been changed.Cell has illustrated under the environment that utilizes this invention method to provide that at cell and this compelling clinical evidence of dynamic change of organizing on the level wound healing process of growing up is similar to the healing of embryo's scar-free wound.

4) fetus scarless wound healing

Compare with spontaneous wound healing with adult's instinct, the fetus wound healing has tangible different aspect inflammatory reaction and somatomedin.The endogenous immunoglobulin infiltration degree is low in the fetus wound healing.[referring to Longaker et al. (1990) J.Pediatr Surg.25:63-69].The reduction of this neutrophilic infiltration is not because the embryo does not have ability to generate neutrophilic leukocyte.Further, the increase of accumulative increase of macrophage and cicatrix has direct relation [referring to Hopkinson et al. (1994) J.Cell.Sci.107:1159-1167] in growing more sophisticated embryo.

In embryo's healing and adult healing, the image of somatomedin is differentiated.In embryo's wound, can measure micro-TGF-β and see Whitby and Ferguson (1991) Dev.Biol.147:207-215] with basic FGF[by immunohistochemistry technology.PDGFs existed in the initial period of embryo's wound and adult wound simultaneously, but disappeared sooner at embryo's wound.This can be interpreted as relevant with slight macrophages infiltration in embryo's wound.Though the shortage of somatomedin threshing can be explained the accumulative reduction of inflammatory cell.This can further cause other somatomedin to be in lower level at embryo's wound.In addition, be immersed in the warm aseptic amniotic fluid, fetus might be under the moistening and isolated environment of such physiology healing of wound, and preventing from scar, not loss of function.

5) wound healing that utilizes condition that the inventive method provides to realize

The adult finishes the healing of wound with complete allelotaxis's form, carries out under the rugged environment comparing with fetus more.Wound is for " normally " inflammatory reflection that wound is produced at the wound surface upper machine body, and negative effects such as the factor of external source such as bacterial infection and further inflammatory reflection are responsive.As above discussed, popular thinking model thinks that the healing of adult's wound must be the cicatrix healing aspect trauma care, because on one's body the adult, the inflammatory wound healing of " normally " is the quality of sacrificing healing for the danger that reduces infection.This present invention has changed this doctrine, if the extraneous suitable condition that provides has been provided for it, the intrinsic self-regeneration and the regenerated ability that have of adult will be brought into play fully so, damage is produced reaction, the agglutination of wound can be simulated the process of pregnant body early embryo wound healing, realizes the no cicatrix healing of serious skin injury.

The inventor utilizes skin, and the organ of this human body maximum is as tissue repair and regenerated model, showed that adult's skin can cultivate the adult stem cell with regeneration capacity by original position, realize regenerating and duplicate, and do not lose its 26S Proteasome Structure and Function, comprise the appendages of skin.Under using the situation of the technology that this invention comprised, controlling dynamic change in cell in the wound healing process and the tissue.

Fig. 5 A-C has shown behind deep ii degree burn the 10th day cell and histogenetic change.Show as Fig. 5 A, after wound the 1st day, epidermis coagulation necrosis and the degeneration of high dermis collagen fiber.In this stage, become somatic cell that damage is reacted, begin to activate and induce (will in the next part introduction of this section).Hindered the back the 6th day, by the treatment that the composition that uses invention carries out, slough quilt liquefaction is fully got rid of (Fig. 5 B).Because slough is to get rid of with the method for the method of liquefaction rather than surgery,, avoided the secondary injury that causes owing to surgical operation so remaining living tissue is retained.Adult tissue's cell is induced and is converted into adult stem cell in the living tissue under this condition, and they grow the various tissue stem cells of the needed one-tenth of skin regeneration then, as blood vessel, hair follicle, collagen fiber, stroma and nerve.Shown as Fig. 5 C, after wound the 10th day, there is very active regeneration to occur on the wound surface.As shown in Figure 6, in the wound healing stage, in wound surface, there is a large amount of tissue stem cells to breed actively.After high power is amplified, can observe the special connection (Fig. 7) between regenerated stem cell.

These tissue stem cells directivity is arranged are divided into various types of cells according to the genetic program of just having determined at embryo stage.As shown in Figure 8, various cells move consumingly to the position of their tissue origin of the same clan.Such as, the cell that belongs to skin corium moves down (the Lycoperdon polymorphum Vitt tip is indicated), epidermis cell then move up (the black tip is indicated).High power can be observed fibroblastic anabolism (Fig. 9) after amplifying.Fibroblast is playing an important role aspect the healing of wound surface, produces the collagen that keeps skin texture.Yet, between the healing stage that produces under instinct, spontaneous wound healing or the treatment,, make growth of fibroblasts than more active under the normal situation owing to the somatomedin that the reaction that infection is made increases in conventional method.Fibroblasts proliferation causes producing excessive collagen, and they flock together and form disorderly fiber, also will form cicatrix in wound sealing back certainly.

By contrast, use the method for introducing here, the regeneration of trauma skin does not have cicatrization on deep ii degree burn, only stays level and smooth, softish cicatrix on III degree burn.The inventor believes that fibroblastic growth can be controlled, fibroblast and epithelially be maintained at a physiological level than regular meeting.Use the wound of present composition treatment, the deposition of fibroblastic collagen and fibroblast and epithelial ratio are controlled in a physiological level, and possible reason is that the present composition promotes the fibroblast maturation.In the rat fibroblast culture experiment of in vitro carrying out, under the situation that does not have the present composition to exist, fibroblastic growth is rapid, and shows the form similar to ameboid cell (Figure 10 A), and this and clinical result match.By contrast, the fibroblast that is incubated in the present composition keeps typical ripe fibroblastic form (Figure 10 B).

After wound the 20th day, most of wound was covered by stratified squamous epithelium, and most of adnexa begins to form (Figure 11) in intradermal.Simultaneously, the cellular metabolism refuse also constantly oozes out from newly-generated epidermis.

After wound the 22nd day, regenerating to have normal configuration skin (Figure 12).Under the ultramicroscope that high power is amplified, the connection that can see between corium and the epidermis is fully natural (Figure 13).Also have, collagen fiber are pressed the sequence arrangement (Figure 14) of normal three dimensional structure in newborn skin.

Zooblast that carries out and tissue culture experiment in vitro proves that also the present composition has the mammal of promotion noble cells and propagation of stem cell and the activity of organizing special adhesion uniqueness, so as to keeping the integrity of organ structure.This is consistent with the effect that the present composition clinically pair cell and tissue between the burn patient convalescence produce.

Figure 15 A-D has shown and has cultivated the rat skin cell in vitro, in the Different Results that adds and do not add the present composition.Two groups of all growths (Figure 15 A) healthily of cell within 10 days.But rapid variation has taken place in the survival and the growth that are right after down two groups of cells.At matched group, cell begins death in the time of 30 days; But in the treatment group, cell is still survived and is being kept normal form (Figure 15 B).At the 49th day, at matched group more cell death is arranged, still continue to breed (Figure 15 C) at treatment group cell vigorously.At the 70th day, all dead at the cell of matched group.Completely contradict with it, in the treatment group, cell is growth strong still, almost near merging (Figure 15 D).Viewing duration at 6 months by a definite date, the cell of treatment group are keeping breeding always, do not demonstrate abnormal form.

This result shows that the present composition is the growth of having the ability to promote primary cell, is by the skin primary cell being converted into the epidermal stem cells with lasting proliferation potential by inference.This and the use present composition, what obtain on human body therapy is consistent to becoming somatic effect.

Figure 16 A-C has shown and has cultivated the rat hair follicle stem cells in vitro, in the Different Results that adds and do not add the present composition.Figure 16 as right side row shows that the stem cell survival of matched group, but grows with the form of individual cells.On the contrary, at stem cells hyperplasia of treatment group and inter-adhesive formation cell mass (Figure 16 of left column).There were many cell masses to form at the 41st day, show the form of allied organization; At matched group, stem cell also breeds, but is keeping dispersity, does not form any cell mass.

These results prove the not only capable propagation that promotes of the present composition, also promote the particular tissues adhesion of stem cell simultaneously.This also with use the present composition, what obtain on human body therapy is consistent to becoming somatic effect.

Figure 17 A-C has shown and has cultivated rat skin in vitro, in the Different Results that adds and do not add the present composition.Figure 17 as right side row shows that the migration and the dispersion of cell are arranged at matched group.On the contrary, almost there are not the migration and the dispersion of cell, newly-generated cell keeping adhesion (Figure 16 of left column shows) with skin bit in the treatment group.At the 44th day, the treatment group continued propagation and joins together with skin bit, demonstrates tangible demarcation line at microscopically.On the contrary,, continue to come off, in cultivation, disperse from skin bit at matched group.

These results prove the capable adhesion that promotes cell and its maternal tissue of the present composition, and keep the integrity of a normal skin structure.This also with use the present composition, what obtain on human body therapy is consistent to becoming somatic effect.

In order to monitor the dynamic change of growth of cell in the adult organ in-situ regeneration process and differentiation, utilizing the wound healing of deep burn is clinical model, has showed when treating with the method for this invention, becomes somatic cell how endogenous and extrinsic factor to be produced and reacts.

Show that as following this invention proves that for the first time under the condition that helps physiological tissue repair and neomorph, the embryonic cuticle stem cell is induced and activates on one's body being grown up, and can breed.These conditions are to provide by technology and compositions that application this invention is opened.

In the adult patient's that the shallow III degree of treatment is burnt process, need the regeneration of stem cells of regeneration different skin tissue under the optimal condition that composition components of the present invention provided, to be activated.In these reproducibility cells, adopt immunohistochemistry and immunofluorescence technique, detected embryo's property epidermal stem cells of express keratin 19 phenotypic marker things specifically, i.e. the K-19 keratinocyte.And in the regenerated different time phases of this patient skin, continuous monitoring expressing K-19 regenerative cell's dynamic change.

20 years old female patients is by the two lower limb of gasoline flame burn, and the gross area (TBSA) 35% (Figure 18) burns.Pathologic finding turns out to be the shallow III degree burn of 15% dark II degree and 20%.Microscopically is observed burn wound's tissue slice, shows the necrosis of holostrome Skin Cell, dermal collagen fibre modification, structure disturbance, the microcirculation stasis of blood stagnate (Figure 19).

Monoclonal antibody (McAb) with special mouse anti human keratin 19 types is carried out immunohistochemical detection to normal and burned skin.Observed result shows, this example patient's normal skin epidermis is angulation protein 19 type positive cell (Figure 20 A) seldom as seen.Corresponding, burn wound's skin at the promoting epidermization stem cell population of back 24 hours K-19 stained positive of wound with regard to moderate increase (Figure 20 B).Burnt back 4 days, and around sweat gland, blood capillary and hair follicle, as seen began the potential epidermal stem cells (Figure 20 C) that increases.The skin histology that enters reproduced state is cut into slices at test under microscope newborn epithelial tissue, collagen fiber and the skin embryo base (EB) (Figure 21 and 22) of visible active proliferation.

Burn back 7 days (Figure 20 D) and 14 days (Figure 20 E) promoting epidermization stem cell continue to increase, and reach peak value.To burning back 21 days (Figure 20 F) and 28 days, regeneration of stem cells quantity reduces to certain level again.

Hindered back 20 days, the section of wound tissue in the healing is observed under ultramicroscope, and visible epithelial cell is connected (Figure 29) with hemi desmosome between the basement membrane.Further, the connection of the desmosome between the spine-like cell has also formed (Figure 28).

Hindered back 30 days, should cut into slices, under ultramicroscope, observe demonstration, adopt method treatment of the present invention, make regenerated skin recover normal physiological structure (Figure 24) from the newborn skin histology that patient gets on one's body.And in the regenerated new skin, the thickness of collagen fiber and spatial arrangements are all normal, and diameter 0.1 μ m～0.5 μ m has light and dark periodicity (64nm) band (Figure 26).Have a liking for silver-colored stained and show, adopt method and composition of the present invention to treat back 30 days, basal layer of epidermis basement membrane regeneration active (Figure 25).

For confirming that new skin is patient's autoregeneration rather than ectogenic, hinder patient and the section of getting from new skin to have been carried out immunohistochemical staining in back 30 days.To using AE ₃The immunohistochemical analysis that painted tissue slice carries out finds that it is AE ₃Male squamous epithelial cancer shows that skin is (Figure 27 A) that gets this showing of autosynthesis.Regeneration skin carries out and is consistent therewith, AE _iPainted tissue slice shows AE ₁Glandular epithelium albumen be negative (Figure 27 B).These results confirm first, and new human organ can be at the body in-situ regeneration, and regenerated organ still organizes level all to have normal 26S Proteasome Structure and Function (Figure 23) at cellular level.

In dark II degree (degree of depth part corium burn) or darker burn wound, the epidermal stem cells that is present in stratum basale is damaged fully.More meaningful is that epidermis and corium all holostrome are destroyed, have only subcutaneous tissue and fat deposit still alive at shallow III degree burn (full pachydermia burn) with having more challenging.With conventional method is the full pachydermia burn of dryness therapy and dermatoplastic treatment burn, and wound sealing as a result has the afunction of the disfeature cicatrix and the substantial appendages of skin.

Yet as above-mentioned, two lower limb suffer the adult patient of dark II degree and III degree burn, and the recovery from illness of can regenerating of its skin does not have its substantial structure and the forfeiture of function.So, where is the histiocytic source of forming this regeneration organ?

Here, the present invention has done answer by clinical practice for this problem, and the result of clinical treatment research confirms, if not whole, derives from the regeneration epidermal stem cells to the small part epidermis cell.Shown in Figure 20 B-G, when human body was in active tissue repair and skin regeneration, these stem cell were the K-19 positive cell.These regeneration epidermal stem cells propagation, differentiation form the keratinocyte of the specific type that can synthesize different keratin (as 9 type keratin, 16 type keratin), these keratinocytes through epidermis that moves up.These cells can continue to move up, and further are divided into the keratinocyte that can synthesize than hard keratin (as 1 type keratin, 10 type keratin), and these are the contained typical angular albumen of ripe epidermis cell.

But it should be noted that having only with K-19 here is the regeneration epidermal stem cells as the labeled cell of certification mark thing.The regeneration of stem cells of other tissue such as blood vessel, hair follicle, collagen fiber, stroma and nerve etc. also is activated simultaneously, breeds, breaks up certainly, forms various histiocytes, to realize that an organ with complete function is at the body in-situ regeneration.

The next problem that needs to answer is: " regenerative cell comes wherefrom? " under normal physiological condition, some cell long-period is stagnated the G in cell cycle ₀Phase or G ₁Phase, the propagation activity just appears under the situation that condition becomes favourable.Some cell can continue to carry out separatist activities in organic whole life process, stem cell continuously is provided.Parton cell differentiation behind the stem cell division is for carrying out the mature cell of certain particular function, and another part daughter cell then keeps continuous multiplication capacity always.In order to keep the integrity of normal skin, epiderm skin basal layer stem cell can constantly carry out division growth.Newborn cell epidermis direction upward moves.When arriving the spinous layer deep, can divide again two or three times, then lost cell division growth ability.

As mentioned above, at dark II degree and III degree burn, the epidermis of wound surface and corium deep layer all are damaged, and the stem cell of stratum basale is total waster also.According at cell with organize the agglutination of the observed this wound surface of level, the inventor thinks, remaining in the subcutaneous tissue around hair follicle, sweat gland and the blood capillary etc. and still activated mesenchymal cell is the source of most of (if not whole words) regeneration of stem cells comprises multi-functional epidermis stem cell.

This theory has obtained the support (Figure 30) of the data that obtains from the downright bad burn patient of the facial full pachydermia of another one on one's body.As shown in figure 31.

When body is reacted by wound, or (with) under the stimulation of the contained active component of the present composition, remaining and still have the mesenchymal cell in the vigor subcutaneus adipose tissue to be activated, and be converted into adult stem cell (ASCs).These adult stem cells are versatilities, under the regeneration condition that the present composition provides, these adult stem cells can be to the different directions directed differentiation, generate the tissue stem cell that forms various tissues, as (Figure 32) such as corium, epidermis, blood vessel, hair follicle, collagen fiber, stroma and nerves.These tissue stem cells that come from their maternal organ are coupled to each other, and follow between the period of embryo with regard to established gene program, unite (Figure 33 A and B) mutually with a kind of organ particular form.

These special organization stem cell carry out original position and cultivate generation filial generation stem cell under the regeneration condition that the present composition provides, parton is induced for stem cell can carry out the tissue specificity differentiation, form various histiocytes, to be implemented in organ of internal in-situ regeneration with complete function.These cells by form that they maternal organs have special with typically is connected the associating (for example, the desmosome connection between two spine-like cells that Figure 28 shows) that realizes each other, cause the regeneration of cambium like this.Figure 34 has shown blood vessel and the neural special associating of organ; And under the condition that provides using technology of the present invention of Figure 35 demonstration, and the formation of hair follicle during the skin regeneration process of carrying out.Regenerated cambium is cultured under the advantage that the compositions of this invention provides, special, the typical connection that has by the maternal organ that forms them connects each other together, is connected with hemi desmosome between the substrate plate as the epithelial cell as shown in Figure 29.Then, these cambiums condense together in the distinctive mode of organ and constitute new organ.As shown in figure 36, the appendages of skin comprise that blood vessel, nerve and various body of gland all are reproduced, and the newborn skin of formation that condenses together.Finally, newborn intraorganic organizing gradually reached maturity, and forms corresponding with it adult tissue, thereby constitutes regenerated, Full Featured organ.By getting in touch between life entity inner cell and cell, cell and tissue and tissue and tissue, tissue and organ can be reproduced and repair their physiological structure and function.For example, prove that in the above a health has been lost the adult of tangible most of epidermis and corium, can recover skin new, that have normal configuration and function (Figure 25) again.

These discoveries and invention have important in theory meaning and practice significance.At first, they show that first by the cultivation of original position stem cell in vivo, adult tissue and organ can be realized repairing and regeneration, recover whole physiological functions.Scientists and doctors are dreaming of to realize beautiful like this result always, but never realize clinically.The inventor thinks that by transplanting the stem cell of In vitro culture, although obtaining certain achievement aspect the epidermis of repairing damage and the corium, such wound healing is not physiological.In other words, utilize the skin of implantation method reparation to stay odd-shaped cicatrix, lost the physiological function of the appendages of skin such as hair follicle, apocrine and secreted sweat gland etc.At microscopically, have only among the present invention, the iuntercellular that the healing of wound surface shows as same tissue connect and adjacent tissue between being connected of (as epidermis and corium) reached complete physiological recovery on the 26S Proteasome Structure and Function.By contrast, utilizing the connection between the tissue of other method reparation is pathologic reconstruction, has lost original natural 26S Proteasome Structure and Function.

Secondly, this is for the first time in fully grown human body, autologous tissue repair and the neomorph process in, the versatility embryonic stem cell is induced or is activated.As mentioned above, utilize in the wound surface physiological agglutination of method guiding of the present invention, a large amount of regeneration of stem cells is expressed as the K-19 type in the wound surface.As everyone knows, 19 type keratin are expressed in the basal cell layer of fetus epidermis and human fetus's growth hair.Therefore, original position is cultivated these embryonic stem cells in vivo, is embodied as the reparation of soma and the regeneration of organ, is not only innovation medically, and developmental biology and cytobiology are had far-reaching influence.

4. the composite formula and the application method that are used for tissue repair and neomorph

The present invention is animal, the particularly human new Pharmaceutical composition that a kind of pharmacy or threpsology aspect are provided.

5. remaining living cells is caused the compositions and the method for the removing slough of minimum injury

The present invention also provides the compositions and the method for the removing slough that causes minimum injury, to preserve i or I tissue or intraorganic remaining living cells.

In the i or I tissue, cell produces series of biochemical reactions for the various signals that derive from microenvironment, often is to be final result with the cell death.Cell has two kinds of dead modes: necrosis and apoptosis.Necrosis is that cell is by physical property strength, as to organizing calorifics, sharp device and damage exogenous chemical, the dead mode that the back is common.In other words the cell death of apoptosis or sequencing, is that a kind of intrinsic self-destruction gene program by them is controlled, to the reaction of making as the performance of chemotherapy and apoptosis regulatory protein.

The dead mode of solencyte does not organize interior dead cell need be eliminated so that promote the regeneration of tissue.If non-viable non-apoptotic cell is stayed the i or I position, the various biochemical products that derive from these cells will cause the inflammatory reaction of health, and this can hinder the regeneration of tissue and increase the weight of infringement to remaining living cells.

Opposite with the surgical debridement method of the incrustation of routine and slough, the invention provides a kind of new method and solve this problem that many doctors are run into when treatment wound and ulcer.Traditional surgical debridement often causes remaining living tissue secondary surgery damage, and this regeneration to tissue and organ is disadvantageous according to the present invention.The enzyme process debridement of carrying out with protease generally has deleterious cellular effects to survivaling cell.

According to the present invention, the mode that slough is discharged by liquefaction is removed from wound.In order to obtain this effect, new compositions has exclusive three-dimensional physical arrangement.

In one embodiment of the invention, contain Cera Flava in the compositions, be lower than the three-dimensional frame structure that forms the Pigeon Hole sample under 25 ℃ the condition, oil droplet is wrapped in the Cera Flava Pigeon Hole.

Say that further compositions of the present invention can also comprise the Cera Flava of 1 weight %～20 weight %, be preferably 2 weight %～15 weight %, 5 weight %～10 weight % are best.

The inventor has designed similar Pigeon Hole sample three dimensional structure by excavating Cera Flava with the different calorifics-physics characteristics of oil.Adopt technique known, dissolve when Cera Flava is heated 70-80 ℃.Next step, the Cera Flava that will dissolve mixes with oil, as animal or plant oil (as Oleum Glycines, Oleum sesami and Semen Maydis oil), begins refrigerative gradually ambient temperature (just 20-25 ℃) then.Because Cera Flava gets soon than oil cooling, the Cera Flava of hardening forms the three-dimensional frame structure that is surrounded by oil droplet in little " Pigeon Hole ".The Pigeon Hole spline structure that Figure 37 has depicted Cera Flava formation includes oil droplet.Ideally, oil droplet is included in respectively in separately the Pigeon Hole, each other not contact.The size of Pigeon Hole is better at 5～50 μ m, and 10～30 μ m are better, and 15～20 μ m are best.

Figure 38 shows the Cera Flava of composition concrete under the ultramicroscope about 10%.Cera Flava has formed Pigeon Hole sample three dimensional structure in fact as shown in figure 38, and each independent oil droplet is included in the inside.

In order to keep the integrity of structure, can contain the water of minute quantity in the composition, weighing less than of water is 1% better, is lower than 0.1% better, is lower than 0.01% best.

Contrivance exclusive structure when using its liquefaction to remove slough, bringing into play important effect.Damage the wound surface of tissue as burn patient when contrivance is applied to, the release (Figure 39) of the oil droplet in the Pigeon Hole that Cera Flava forms causes series of biochemical reactions.Owing to do not wish that the accurate molecular mechanism of being reacted fetters, the inventor believes, and five kinds of biochemical reaction take place between oil droplet on the wound surface and slough at least, comprise aquation, enzymolysis, corruption, saponification and fatization.

The first step, when contrivance was used on the wound surface, contact wound Cera Flava Pigeon Hole sample three dimensional structure was decomposed by body temperature heating back, and oil droplet is released (Figure 40).The oil droplet infiltration that discharges surrounds the slough granule wherein as in the wound tissue.

In second step, the slough that is held by oil droplet begins the aquation (Figure 41) of cell, and the various intracellular enzymes of result are released.

In the 3rd step, the cellular enzymes of release is further decomposed the slough granule that is held by oil droplet.

In the 4th step, by the slough granule of decomposition and corruption and the saponification between the oil droplet, solid slough granule is liquefied.

In the 5th step, by the esterification reaction of liquefaction tissue, effective ingredient can be discharged from wound surface (Figure 44) by the fatty acid esterization in the oil droplet.

At last, along with the Cera Flava Pigeon Hole sample three dimensional structure of contrivance progressively collapses, the oil droplet that more contains effective ingredient is discharged in the wound surface together, removes to hold remaining slough granule.Simultaneously, because the slough of liquefaction and remaining living tissue are incompatible, make these sloughs be accompanied by the collapse of grid framework structure and ooze out (Figure 45).

According to the mechanism of action of this invention compositions, the solid slough of be difficult to removing by traditional method (as surgical debridement) can be transformed into the liquid of automatic discharge wound surface, and living tissue is not caused damage.

This noninvasive method is very useful in some aspects.At first, slough is removed rapidly, thereby prevents that health from producing inflammatory reaction.The second, along with slough is removed effectively, impel the environment of bacterial growth destroyed, so just effectively reduced risk of bacterial infections.

The particularly important is, when slough was removed fully, residual living tissue was not sealed by medicine oil, and on the contrary, the almost transparent film of one deck that residual living tissue is formed on these tissue surfaces protects.As described in Figure 46, form the albuminous coat of layer of transparent on skin living tissue surface, by this albuminous coat, the active component porous in the compositions is gone into living tissue, and metabolite and other Excretas can obtain drain simultaneously, thereby promote regeneration.This film can work to make the granulation tissue of the active fragility of regeneration and the protective layer that abominable external environment is kept apart.To a certain extent, it can be used as the substitute of epidermis, prevents that the living tissue in the skin from avoiding the invasion and attack of external environment.As described in Figure 46, this film has " breathing " function, can make the metabolite automatic jet, and promotes regenerated cell and tissue to absorb alimentation composition and oxygen.

In addition, this by Cera Flava form with the refining molten unique texture that contains wherein of fluid of plant, make wound surface place the physiological moist environment.This small space frame structure is isolated wound surface and external environment, prevents that wound surface is over-drying, promotes that also the living tissue below the medicine film is carried out effectively " breathing ".As described in Figure 47, active water evaporates takes place in the burn wound that is exposed to the rabbit in the outside air, causes wound over-drying.On the contrary, then very low through the evaporation capacity of the wound of this inventive compositions (IC) treatment, and on physiology, keep a reduced levels.Similar with self-controlled group, the water evaporation quantity of wound surface of using conventional dry Sex therapy (as the baking the affected part after applying some drugs dry exposed therapy) treatment is just than the water evaporation quantity height (Figure 48) of the wound surface of this combination treatment of application.

Importantly, when making wound surface place the physiological moist environment, this inventive compositions can not resemble and cause the excessive tissue dipping the vaseline.As the comparison of being done among Figure 49, the evaporation capacity that is coated with the wound surface of vaseline is suppressed in the level of hanging down twice than the wound surface that is coated with IC.On physiology, as the comparison that Figure 50 A and B are done, the burn wound that uses the rabbit of IC treatment is moistening, and from outward appearance to inner essence be liquefied gradually in 48 hours (Figure 50 A).On the contrary, dipping appears in the burn wound that is coated with the rabbit of vaseline, presents the sign that tissue comes off; And oversteeping also takes place in the normal skin around the wound surface.As seen microscopically uses the wound surface of dry therapy treatment, and inflammatory cell infiltration (Figure 51 A) is arranged between slough and living tissue.On the contrary, use the wound surface of this original creation combination treatment, slight inflammatory cell infiltration only occurs at slough and living tissue junction, mild swelling and blood capillary hyperemia (Figure 51 B).On the wound surface of vaseline treatment, inflammatory cell occurred organizing cavity and infiltration (Figure 51 C) in back 48 hours at burn.Same as shown in the table of Figure 52, the wound healing time (15 days) of the rabbit of application IC treatment is faster than the matched group of not accepting any treatment (20 days).These results confirm that this original creation compositions with 3-D solid structure has as protective layer replacement skin and the ability of keeping the skin physiology moist environment.

It is emphasized that this medicine and will make with extra care the molten ingredient that contains also useful other raw materials compositions of Cera Flava of grid framework structure wherein of fluid and be also contained in the invention of this time declaring except adopting.

This novelty compositions can be used as the substrate of a large amount of various medicines, nutraceuticals and cosmetics.Many active component solubilized or be suspended in the medicine oil, these fluid are contained in the grid framework that Cera Flava forms by molten then.Synthetic dosage form can be local, oral, by sucking or other suitable medications are come medication.

6. suppress antibacterial toxicity by non-bactericidal properties mode

The present invention also provides and can suppress toxic composition of broad spectrum of bacteria and method.Compare with the traditional remedies of using antibiotics and alcoholic disinfectant, antibacterial pattern of the present invention is different fully.Usually, use the compositions of this original creation after, bacterial cell is not dead immediately.On the contrary, bacterial cell still has the ability of genetic copying, and the toxicity of antibacterial is also owing to the toxin that this original creation compositions disturbs bacterial cell division to produce is effectively suppressed.According to cytobiology and microscopic study result widely, this inhibitory action is by adjusting the morphology and the cellularity of bacterial cell, and realize by the ecology that changes the cell growth.

Bacterial cell is to belong to the simplest organic prokaryotic cell of finding in most nature environment of formation.Typical bacterial cell is spherical in shape or shaft-like, generally has several microns long, and the structure of bacterial cell is quite simple.Below being called as the protective layer of cell wall, cell membrane is holding the single DNA of containing, RNA, protein and micromolecular Cytoplasm.

Follow a kind of cellular replication mode that is called as binary fission, antibacterial can be duplicated rapidly.Under optimal condition, single bacterial cell divided once in per 20 minutes, thereby produced 5,000,000,000 cells in less than 11 hours.The bacteriotoxin of the immunne response of certain type antibacterial by producing the infected host animal of targeting causes inflammation and organ injury to the animal toxigenicity.If control of bacterial infection just can cause serious organ injury in time, even cause infected host's death sometimes.

The most general bacteriostasis method is the bactericidal action of using antibiotics.In order to prevent bacterial infection, many antibiotics are to be made by Mycophyta.Nearly all known antibiotics is by disturb their bactericidal action of cell cycle performance of antibacterial in the gene replication stage.For example, rifamycin is transcribed into the gene replication of the stage inhibition antibacterial of RNA at DNA.Rifamycin can be by blocking the initial of RNA chain in conjunction with RNA polymerase.Yet most antibiotics disturb bacterial growth in the translating phase of gene replication.These antibiotics combine with the zones of different of bacterial ribosome, thus different step in the Profilin matter building-up process.For example, streptomycin stops the translation initiation complex to the conversion that prolongs ribosomal chain, also causes miscoding.Tetracycline blocking-up aminoacyl tRNA is connected with ribosome A end.At the polypeptide chain of protein synthesis between the extended period, the end of polypeptide chain carboxyl is by from the tRNA molecule of the P end that is positioned at little ribosomal subunit separately, and is connected on A end and the aminoacid that the tRNA molecule links to each other by a peptide bond.The central reaction of this protein synthesis is by the catalysis of peptidy transeferace institute.Chloromycetin energy blocking peptide acyltransferase is to ribosomal effect.When ribosome exactly when the mRNA molecule moves forward three nucleoside, the new peptidyl tRNA of A end is displaced to the P end.This step needs energy, and is promoted by the change of a series of conformations of being induced by the hydrolysis of GTP molecule in a certain ribosome composition and taking place.Erythromycin can hinder this ribosomal displacement that acts on.The difference of 26S Proteasome Structure and Function is disturbed the ribosomal function of protokaryon selectively between these drug utilization protokaryons and the eucaryon ribosome.

Yet some antibiotic can act on prokaryote in the gene translation stage, antibacterial for example, and eukaryote is as mammal.For example, puromycin can cause the jejune release of nascent polypeptide chain by adding growing chain end to.On the other hand, radiating streptozotocin D is by disturbing genetic transcription in conjunction with DNA with in order to suppress the synthetic motion that hinders RNA polymerase of RNA.The common method of another kind of kill bacteria is that (as wound surface) uses ethanol, for example ethanol or isopropyl alcohol on the treatment surface.Ethanol is very effective for kill bacteria, and this may be directly to cause non-viable non-apoptotic cell death to realize by the decomposition fully of bacteria cell wall.Yet these ethanol reagent do not have selectivity aspect cell killing, to such an extent as to and can too stimulate the regenerative cell of damage wound surface new life's fragility.

7. at the composition of external promotion stem cell growth

The present invention is also for to provide method and composition at In vitro culture eukaryotic cell (as the human cell).In one embodiment, tissue culture medium (TCM) is used in the growth of external promotion cell and/or keeps and nourish special cell line or cell type.

In one embodiment, especially provide a kind of compositions for cultivating eukaryotic cells the stem cell of In vitro culture animal.This compositions contains the phytosterin compound that the content that is dissolved in the organic solvent is at least 0.01 weight %.The preferred content range of this phytosterin compound is 0.01%～20 weight %, more preferably is 0.01%～10%, and optimum content is 1%～5%.What can select is that this phytosterin compound can combine with lipid in culture medium, is passed in the cultured cell.

The present invention also provides a kind of cultivation eukaryote, especially in the cell method of the stem cell of In vitro culture animal.This method comprises: with the cell or tissue culture with contain the compositions of content and contact for the phytosterin compound of at least 0.01 weight %.The preferred content range of phytosterin compound is 0.01%～20 weight %, and more preferably content is 0.5%～10%, and optimum content is 1%～5%.

This compositions and method can be used for promoting the cell growth, and do not undergo mutation or gene alteration, and especially, the cell in the culture medium can infinitely divide, and can prevent differentiation.

These compositionss and method also can be used for determining primary cell system to the gene transfer of variation in cell.Primary culture is taken from an organic tissue in advance, is with or without initial cell separation classification step.As a rule, the cell in the primary culture can be removed from culture dish, is used for forming a large amount of intermediate cultures; These cells can repeat in this way to go down to posterity and cultivate several weeks or several months.Such cell often demonstrates many different qualities that belong to their origin thing: fibroblast continuous release collagen protein; The cell that originates from embryo's skeletal muscle merges in culture dish mutually to form the muscle fiber of big autonomous contraction; Neurocyte stretches the neural axon with electrostimulation, and and other neurocyte form nerve synapse; Epithelial cell forms the large tracts of land cellular layer with complete numerous characteristics that epithelial cell had.Yet primary culture is just dead after 50 generations usually under normal operation.As to being grown in (embodiment 1, Figure 15 A-D) that experiment confirmed that mouse skin carries out in the culture medium that contains this inventive compositions, cell can be bred, and does not show any unusual or phenotype of transforming.

This compositions can be added to certain amount in the conventional tissue culture medium (TCM), with the quantity of certain special cell or tissue type that is suitable for growing.Although tissue culture medium (TCM) contains the micromolecule of specific quantity, for example salt, glucose, aminoacid and vitamin also contain in most culture medium and define indefinite macromole mixture, and the natural extract of horse serum or hyclone or Embryo Gallus domesticus is arranged.Chemically the culture medium that does not contain serum of Que Dinging comprises be beneficial to the various somatomedin that cell is survived and bred in culture medium.This class culture medium also comprises carries the transferrin of ferrum to cell.Other protein signal molecules are absolutely necessary for existence, growth and the propagation of special cells type.

This invention compositions can promote some or all certain to be suitable for cultivating the function of composition of the typical culture of mammalian cell.Below enumerated the kind of these tissue culture's reagent, certainly be not limited in these, 1) aminoacid is as arginine, cystine, glutamine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine; 2) vitamin is as biotin, choline, folic acid, nicotine, pantothenic acid, vitamin B6, vitamin B1 and riboflavin; 3) salt, as NaCl, Kcl, NaHPO ₄, NaHCO ₃, CaCl ₂And MgCl ₂4) protein is as insulin, transferrin, special somatomedin; 5) other: glucose, penicillin, streptomycin, phenol red and whole serum.

Embodiment

Following examples 1-3 represents the upgrowth situation of mammal cell in containing the culture medium of the present composition.

In following embodiment, the compositions of experiment in vitro confirmation the present invention original creation is adhered to the effect with uniqueness for propagation and the tissue specificity of the stem cell of mammal that promotes normal differentiation and mammal, also keeps the integrity of skin texture simultaneously.Skin tissue cell, hair follicle stem cells and skin graft are all taken a sample from rat or mice, and cultivate external.Cell or tissue are divided into two groups: matched group is cultivated (MEM completely) in the cell culture medium of routine, and the treatment group is cultivated in the conventional culture medium that adds this original creation compositions.

Embodiment 1 mouse skin cell culture

Take its fresh skin immediately after mice caused death, and at 6 hole culture dishs (about 10 ⁴Individual cell/ml, 7ml/ pond) cultivates among the MEM in.After three days, as seen these cell growths are normal, and at the 8th day that cultivates, these cell adhesions were in the basal layer of Tissue Culture Dish.Add the about 3g of said composition in the treatment group, the present composition is by about 0.01% sitosterol, about 0.3% baicalin and about 0.2% berberine composition, and above compositions all is blended in the Oleum sesami.The MEM that in matched group, adds 2ml.Changed once the microscopically performance of every 2-3 days record cultures with two groups of every 4-5 of growth medium days.

Figure 15 A-D shows for the mouse skin cell culture is having the present composition to exist, or the experiment in vitro result under the situation about not having.Right hurdle picture is taken from matched group, left hurdle from the treatment group.The tenth day, two groups cell visible growth (Figure 15 A) in good condition.Yet significantly changing appears in the survival rate of two groups of cells and growth conditions.At matched group, cell begins death in the 30th day, and the cell of treatment group is still survived, and has kept normal form (Figure 15 B).At the 49th day, more cellular control unit death, the cell of treatment group continues to keep active propagation (Figure 15 C).At the 70th day, all cells of matched group was all dead.Visibly different with it is that the cell of treatment group is still grown effectively and almost merged (Figure 15 D).In six months by a definite date observation period, the cell of treatment group is bred all the time, and abnormal form change do not occur.

These results confirm that this inventive compositions has the ability that promotes the primary cell growth promoter, be by inference by with former generation Skin Cell convert epidermal stem cells to and realize with potential lasting multiplication capacity.This be consistent to the somatic effect of one-tenth with present composition treatment.

The cultivation of embodiment 2 rat hair follicle stem cells

Take the hair follicle stem cells of rat after rat caused death immediately from the knuckle portion of hair follicle, in containing 24 hole MEM/5%FCS culture dishs (there is 2ml in every hole), cultivate.After 5 days, visible these cell well-growns, and attach to the basilar part of Tissue Culture Dish.Add about 1g present composition in the treatment group, said composition contains and is dissolved in stigmasterol, cupreol, campesterol in the silk floss oil, and content is 6 weight %, and the MEM of 1ml is added into matched group.Culture was observed 41 days, write down the microscope performance of culture.

Figure 16 A-C shows: the experiment in vitro result that the hair follicle stem cells of rat carries out in the culture medium that contains or do not contain the present composition.Right hurdle picture shows matched group, and left hurdle is organized from treatment.Shown in the right hurdle of Figure 16, the stem cell survival of matched group, but independent growth be.On the contrary, the stem cell of treatment group breeds, and formation clone (seeing hurdle, Figure 16 left side) is merged in beginning mutually.The 41st day, the treatment group formed many clones, the form of allied organization occurred.Yet, although the cell of matched group has also been bred, still scatter, do not form any clone.

These results confirm that the present composition not only has the ability that promotes breeding, also promotes stem cell tissue specificity adhesive force.This is consistent with the effect that one-tenth somatic cell with this combination treatment is produced.

Embodiment 3 mouse skin tissue cultures

Take its fresh skin immediately after mice caused death, cut into lamellar, cultivate in MEM culture dish and 6 pond MEM/15%FCS culture dishs (5ml/ contains in the pond 3 skins).After 4 days, these skin grafts are attached to the Tissue Culture Dish basilar part.Added about 6g present composition in the treatment group, said composition is dissolved in hitodesterol and the yellow berberine of 0.001 weight % of 1 weight % in the soybean oil.Added 6mlMEM at matched group.These cultures were observed 44 days, write down the microscopically performance of culture.

Figure 17 A-B shows that mouse skin is organized in or does not have a result who carries out experiment in vitro in the culture medium of said composition.Right hurdle picture is from matched group, and left hurdle shown in the right hurdle picture of Figure 17, occurs cell migration and dispersion from the treatment group in the matched group, and on the contrary, the cell migration of treatment group and diffusion are rare, and newborn cell still is attached to skin graft (hurdle, Figure 16 left side).The 44th day, the cell of treatment group continued propagation, merge with skin graft, and the visible edge clearly of microscopically.On the contrary, cell continues to shift from skin graft, at the culture medium internal diffusion.

These results confirm that the present composition has the complete ability that promotes the similar tissue with it of cell to merge and keep the normal skin structure.This effect with the human adult cell of using the said composition treatment is consistent.

Embodiment 4 epidermal stem cells in vivo with the inducing and breeding of original position

Following examples confirm that first the embryonic cuticle stem cell is induced and activates, and can become in the human body to breed under the condition of physiology's reparation that helps organizing and neomorph.Such regeneration condition is finished by using this method and the present composition.In addition, the dynamic change of these embryonic cuticle stem cell is to treat on the skin of aitiogenic experience skin regeneration detected to using this method and composition.

During suffering from the adult treatment of shallow III degree burn to one, the ideal conditions that the reproducibility stem cell of the various skin histologies that need be used for regenerating is contained the present composition to be provided activates.Between these regenerated cells, the embryonic cuticle stem cell of presentation markup object angle protein 19 type is detected especially by using immunohistochemistry and immunofluorescence technique.Expression regenerative cell's the keratic dynamic change of 19 types is also arrived in different time detecting during this patient's skin regeneration.

This patient uses to be contained the stigmasterol that is dissolved in the middle of the Semen Maydis oil that accounts for composition total weight 20% weight and treats in the compositions of the present invention.Content of baicalin is 2 weight % in the said composition.

20 years old women's extremity are by petrol burn, and area is 35%TBSA (Figure 18).Pathological analysis shows 15% degree of depth part corium burn and 20% shallow full pachydermia layer burn.The microscopy of taking from the portion of tissue of burn wound shows the structure disturbance and the microcirculation retardance of the necrosis of full thick-layer Skin Cell, degeneration and intradermal collagen fabric.(Figure 19).

The skin of injured area and organize respectively at the 24th hour and the 4th, 7,14,21 and 28 day and take behind patient's burn, and they are kept in vitro and liquid nitrogen freezing is embedded in the Tissue-Tek OCT chemical compound also and liquid nitrogen freezing then.10 μ m slabs make in the thermoregulator household freezer can carrying out.

Use one biotin-avidin DCS system non-direct IF staining is carried out in section.The temperature of frozen section and 10% horse serum remained on 4 ℃ of constant temperature following 20 minutes, added 1: 20 dilute solution of mouse anti human keratin 19 type monoclonal antibodies (first kind of antibody) then.These the section be maintained at once more 4 ℃ constant temperature one the whole night.After the phosphate buffer flushing, in section, add the anti-mouse IgG antibody of biotinylated horse (second kind of antibody) (originating from California, USA Burlingame Vector laboratory) of 5 μ g/ml, under 4 ℃ of constant temperature, preserved one hour then.These sections are rinsed and are placed in the glycerol of the p-phenylenediamine (PPD) that contains 10%PBS and 1%.The section of Zu normal skin is dyeed in mode of the same race in contrast, but does not add first kind of antibody.Specimen is observed under the Olympus TIRF, takes a picture with the ASA400 Kodak film.

This example is to use special mouse anti human keratin 19 type mab treatments to come normal and burned skin are carried out immunohistochemical detection.The result has disclosed in this patient's normal epidermis, and a few cell is keratin 19 positives (Figure 20 A).On the contrary, burnt back 24 hours the regenerated epidermal stem cells (Figure 20 B) that exists keratin 19 dyeing of moderate quatity to be positive in the skin of wound surface.Burnt the quantity of regenerated epidermal stem cells rising (Figure 20 C) around sweat gland, blood capillary and the hair follicle back 4 hours.The microscopy of the section of regeneration skin shows the newborn epithelial tissue active proliferation (Figure 21 and 22) of collagen fiber and skin embryo basilar part.

At the 7th day (Figure 20 D) and the 14th day (Figure 20 E), epidermal stem cells continues to increase, and reaches summit during this period.Up to the 21st day (Figure 20 F) and the 28th day, it is one low-level that the quantity of regenerated stem cell is reduced to.

Burn back the 20th day takes the microscopy of section of the wound surface of self-healing to show, has formed hemi desmosome connection (Figure 29) between epithelial cell and the basement membrane.In addition, also formed desmosome connection (Figure 28) between the spine-like cell.

Burnt back 30 days, and taked to show, kept self normal physiological structure (Figure 24) by using this regenerated skin of invention technology of reporting from the electron micrograph of the section of patient's newborn skin.Equally, the size of the collagen fiber of regenerated new skin and cubic arrangement all are normal, and size is 0.1-0.5 μ m, has the alternate cycle band (63nm) of typical bright bank (Figure 26).The silver dyeing of having a liking for of cutting into slices shows, uses the method and composition of others' invention and treats after 30 days the basement membrane active proliferation (Figure 25) of epithelium basal layer.

For determine skin be regeneration from the patient from body rather than from other external sources, the patient burn taked its regeneration skin in back 30 days section to carry out immunohistochemical staining.With the positive protein of the visible squamous epithelial cancer of immunohistochemical analysis of the painted section of AE3, the spontaneous self-regeneration (Figure 27 A) of expression skin.Therewith consistently, shown the negative albumen (Figure 27 B) of glandular epithelium with the painted section of AE1.These results confirm that first a human neologism can duplicate with original position in vivo, and at cell and organize level to keep normal physiological structure and function (Figure 23).

In dark II degree (degree of depth partial-thickness burn) or worse burn wound, the epidermal stem cells that is positioned at stratum basale is impaired.More interestingly and challenging be, in the burn wound of shallow III degree (full thick-layer burn), complete epidermis and corium and subcutaneous tissue are impaired, and the fat deposit of skin is still survived.Traditional remedies such as application dryness therapy and skin transplantation can cause the normal function forfeiture of healing of wound cicatrix and cutaneous appendage to the treatment of full thick-layer burn.Yet as implied above, suffering from the adult's of dark II degree and III degree burn skin can Regeneration and Repair and do not lose skin texture and function.Is the tissue that constitutes the regeneration organ which cell source is formed?

The present invention originates from the answer that the reproducibility epidermal stem cells provides problem by proving clinically to the epidermis cell of small part (if not all).Shown in Figure 20 B-G, these stem cell dyeing are keratin 19 type positive reactions, and this moment, the tissue repair and the skin regeneration of health were active.These reproducibility epidermal stem cells propagation and differentiation can be synthesized the keratic keratinocyte of other types with the generation specific type, for example, keratin 9 types and keratin 16 types, they can make progress and move toward the epidermis direction.The cell of these differentiation continues to break up upwards, forward with generation and has synthetic stronger keratic Keratinocytic ability, for example keratin 1 type and keratin 10 types, and they are the typical angular albumen of sophisticated epidermis cell.

Yet, also it is emphasized that and have only the reproducibility epidermal stem cells to obtain labelling by keratin 19 types of using as the snoop tag thing.The reproducibility stem cell of its hetero-organization also is activated as blood vessel, hair follicle, collagen fiber, stroma and nerve, in vivo with the original position proliferation and differentiation with the required all cells of the neomorph that produces certain perfect in shape and function (Fig. 6 and 11).

Another problem is: " from where are these reproducibility cells? " under normal physiological condition, some cell long-period is in the G of cell cycle ₀And G ₁Phase, and their propagation only just begins under the favourable situation that these conditions become.Yet, the propagation of some cell continue to run through with human life all the time, like this, just need the lasting supply of stem cell.The daughter cell differentiation and maturation of part stem cell, the cell of specialization and their part keep multiplication capacity.At normal unmarred skin, the stem cell of stratum basale has the ability that continues propagation.New proliferating cells upwards moves towards the epidermis direction.When arriving the deep regional of spinous layer, propagation occurs two to three times, just loses their multiplication capacity then.

As discussed above, in dark II degree and III degree burn wound, the deep layer of epidermis and corium is impaired, and the stem cell of stratum basale is also impaired.Based on to the wound healing process at cell with organize the observation of level, the inventor believes, remaining mesenchymal cell (Figure 31) can provide most (if not all) reproducibility stem cell around being positioned at subcutaneous tissue hair follicle, sweat gland and blood capillary, comprises the epidermal stem cells of pluripotency.Mesenchymal cell in residual living tissue is activated and is transformed into adult stem cell (ASCs) because of reacting to bodily injury and/or by the stimulation generation of the active component in this invention compositions.These adult stem cells are pluripotencies, and under the regeneration condition that invention compositions thus provides, adult stem cell can be induced directly to be divided into various tissue stem cells, for example corium, epidermis, blood vessel, hair follicle, collagen fiber, stroma and nerve.The tissue stem cell of these specializations is to cultivate in the regenerative environ-ment that provides of invention compositions thus to produce the filial generation stem cell, and their part is induced, tissue specificity ground in vivo or original position be divided into the needed various cells of certain function neomorph.

For example, provide the Keratinocytic epidermal stem cells of all kinds may originate from mesenchymal cell.To the reaction of damage and under the regenerative environ-ment that invention compositions thus provided, the residual interior mesenchymal cell of living tissue of affected area changes adult stem cell into, and their part directly is divided into the reproducibility epidermal stem cells then.This epidermal stem cells can synthesize special cytokeratin 19 types, so just can be determined by the immune molecule chemical method.At this moment, by using anti-human keratin 19 type monoclonal antibodies, in the subcutaneous tissue of dark II degree and shallow III degree burn wound, can detect the reproducibility epidermal stem cells clearly.

Show that as above after using method treatment of the present invention, the quantity of expressing the K-19 of reproducibility stem cell increases along with the healing gradually of wound, reaches a peak value, quantity descends after nearly all tissue regeneration then.These results show, even cause epidermis and the destructive III degree burn of corium holostrome for one, by using the condition that method of the present invention provides, regenerated epidermal stem cells still can be activated from remaining living tissue and induce.

On wound surface, use the present composition, and implement rational clinical management, the stem cell of human reg can be activated and breed to guarantee spontaneous, the physiological regeneration of healthy skin, realizes the scarless healing of deep ii degree burn and only forms the cicatrix of smooth, soft at shallow III degree burn.

The above results shows that embryonic cuticle stem cell (K-19 keratinocyte) is induced or activates because of the reaction to burn wound, and breeds under the regenerative environ-ment that compositions of the present invention provides.Rapid change takes place in the quantity of these stem cell in the process of skin regeneration, disclosed first under the advantage that provides in the external world, by activating and the propagation autologous stem cells, become the person is how to guide autologous tissue's reparation and neomorph with original position in vivo.These regeneration of stem cells are considered to the source of epidermis cell, even be not all, also are that skin regeneration is necessary.

Further, based on clinical observation at tissue and cellular level, the inventor believes that adult stem cell produces after the tissue stem cell, a kind of tissue stem cell of particular tissues type (for example epidermal stem cells) induced generate renewable one-tenth they with the needed various types of cells of source tissue (for example various types of keratinocytes are as K-1, K-9, K-10 and K-16).These cells are distinctive by forming, have the connection of homology tissue signature and transmit information (desmosome between two spine-like cells that show as Figure 28 connects) mutually, thereby cause the regeneration of cambium.Regenerated cambium is cultivated under the advantage that the synthetic of this invention provides, and is distinctive by forming, have the connection of homology tissue signature and transmit information mutually, and for example the epithelial cell that shows of Figure 29 is connected with hemi desmosome between the basement membrane.In addition, these new lives' tissue condenses together with organ specific form and constitutes a newborn organ.At last, the tissue development maturation in the newborn organ is their corresponding adult tissues, constitutes regenerated, all-round organ.By these associatings between the intravital cell-cell of life, cell-tissue and tissue-tissue, tissue and organ can be rebuild under the situation of their physiological structures and function and regenerate.For example, confirmed in the above that one has been lost the epidermis of her health very large area and the adult of corium, the new skin that can be had normal configuration and function again covers (Figure 23 and 24).

These discoveries and invention all have great importance in theory with in the practice.At first, they have disclosed for the first time by original position and have cultivated stem cell, adult tissue and organ can be under the situation that keeps complete physiological function Regeneration and Repair.This achievement is that the scientist and the doctors that are engaged in this field work dream of, but never realizes clinically before this.Even the inventor believes the outer stem cell of cultivating of transplant and has obtained gratifying, limited success aspect impaired epidermis and the corium repairing that still, the healing of this wound surface is not physiological.In other words, use this implantation method to repair skin can cause the disfeaturing forfeiture of scars and skin appendages (as hair follicle, apocrine and eccrine sweat gland) physiological function.Microscopically has only the invention that this item declares to confirm, in the same tissue between the cell and between the adjacent tissue physiological that can realize on the 26S Proteasome Structure and Function completely that is connected of (for example epidermis and corium) rebuild.In contrast, use other method in this field, the connection reconstruction between tissue is pathologic, shows abnormal 26S Proteasome Structure and Function.

Secondly, this is for the first time in a full grown human body, during himself tissue repair and neomorph, the embryonic stem cell of pluripotency is induced and is activated, as implied above, use the method for this invention, in wound surface physiological agglutination, a large amount of regeneration of stem cells express keratin 19 types in the wound surface.As everyone knows, 19 type keratin are expressed at fetus stratum basale cell with at the knuckle position of the hair of human foetus growth.Cultivate these embryonic stem cells with original position in vivo, be used for adult tissue and repair and neomorph, be not only a medical science innovation, and developmental biology and cytobiology are had far-reaching influence.

The differentiation of stem cells of embodiment 5 stomach intestinal tissues

The present composition and method can be in order to activating or to induce the reproducibility stem cell in the stomach intestinal tissue, with the damage and the illness of the mucosa of repairing the organ in gastrointestinal tract.Compositions provided by the invention can be treated the human body alimentary canal illness, use a kind of compositions that is dissolved in the sterol compound in the oil that contains in the present embodiment rat digestive tract, sterol compound wherein, cupreol, the percentage by weight of content is 20%, and its oils and fats is an Oleum Arachidis hypogaeae semen.The animal model of the gastric ulcer that the result who obtains such as Fig. 3 cure.

The inventor thinks that compositions of the present invention can repair the mucosa of damage effectively; in gastrointestinal; regenerated condition particularly is provided under one's belt; after in gastrointestinal tract, using this compositions; medicine mixes with gastric mucosa; form protecting film; wherein contain mucin; the further stimulation of other compositionss in mucosa and food and the stomach can be separated; in this case; sterol compound in the compositions and other effective ingredient are released the activating and regenerating stem cell, promote mucosa to accelerate to repair, in addition; the present composition also can change the toxicity that suppresses helicobacter pylori effectively by the form that makes antibacterial; by the gastrointestinal regeneration of health, the ulcer situation that helps helicobacter pylori improves, and suppresses the growth of antibacterial indirectly.

The pharmaceutical composition of embodiment 7 inhibition and/or kill bacteria and virus

Compare with the method that application antibiotic and disinfectant are traditional, the present invention discloses by non-bactericidal properties mechanism of action and suppress the toxic new compoistion and method of use of antibacterial.Contain in the unique component that this invention compositions provides and be dissolved in content and be at least zoosterol class or fat-soluble phytosterol in 0.01% oils and fats.。In the present embodiment, use in the compositions that the method for prior art is processed into, contain and be dissolved in Animal fat, for example in the Adeps Bovis seu Bubali, calculate by weight the desmosterol of 0.2 weight %.

Though do not wish that being suppressed the toxic mechanism of action of antibacterial by this inventive compositions limits to, the inventor proposes in the present invention, certain zoosterol class or phytosterol are in case combine with the cell membrane of antibacterial, just may change the structure and the flowability of bacterial cell membrane, cause the change on the morphocytology.The form of bacterial cell takes place to cause serious biophysics and biochemistry to change to antibacterial, and this change may realize by suppressing cell division and bacteriotoxic generation.

A large amount of experimental evidences are supported this hypothesis.Carry out experiment in vitro on the culture medium of various antibacterials containing, antibacterial comprises clostridium tetani, bacteroides fragilis, propionibacterium acnes, Proteus, escherichia coli and bacillus pyocyaneus.

Figure 53 A-C shows: at a morphological change that contains the clostridium tetani cell of growing on the culture medium of this invention compositions.Figure 53 A shows: the normal morphology of clostridium tetani cell is elongated rod-shaped.Be incubated at first and second Dai Chengyi elongated rod shape or the filament shape (Figure 53 B) of the clostridium tetani of the culture medium that contains this invention compositions.In third and fourth generation of clostridium tetani, present very big change on length, has than plurispore formation one to be the drumstick shape, and a little elongated rod shape or filament shape (Figure 53 C).

Figure 54 A-C shows: the form that is grown in the bacteroides fragilis on the culture medium that contains this invention compositions changes.Figure 54 A shows: the normal morphology of bacteroides fragilis is the median size bacillus.Bacillus different in size appears in its third and fourth generation on the culture medium that contains this invention compositions, and has antibacterial to assemble fusion (Figure 54 B).In the 5th, six generations of bacteroides fragilis, be similar to pellet shapes, and have many antibacterials gatherings to be fused into irregular spheroidal (Figure 54 C).

Figure 55 A and B show: the form that is grown in the propionibacterium acnes on the culture medium that contains this invention compositions changes.Figure 55 A shows: the form of normal propionibacterium acnes is thin rod-short.On the contrary, in third and fourth generation of cultivating the propionibacterium acnes on the culture medium that contains this invention compositions, is and is uneven in length shaft-like or filament shape (Figure 55 B) not of uniform size.

Figure 56 A-C shows: the form that is grown in the Candida albicans on the culture medium that contains this invention compositions changes.Figure 56 A shows: the normal morphology of Candida albicans is an oval, visible more blastopore.The spheroidal that third and fourth generation of Candida albicans occurs differing in size on the culture medium that contains this invention compositions can be seen some bar-shaped thalline and a little blastopore (Figure 56 B).Bar-shaped or elongated rod shape appears in the 5th, six generations of Candida albicans, and the antibacterial silk of visible varying length, blastopore be rare (Figure 56 C).

Figure 56 D and E show: the germ tube result of the test of Candida albicans.The normal germ tube generation rate of Candida albicans is 90%.On the contrary, be grown in Candida albicans on the culture medium that contains this invention compositions the 5th, hexabasic germ tube generation rate only is about 0.5-2% (Figure 56 E).

Figure 57 A and B show: the form that is grown in the Bacillus proteus on the culture medium that contains this invention compositions changes.Figure 57 A shows: the normal morphology of Bacillus proteus is thin rod-short.On the contrary, first and second Dai Chenggeng that is grown in the Bacillus proteus on the culture medium that contains this invention compositions is long, bigger shaft-like or essentially continuous fine thread shape (Figure 57 B).

Figure 58 A and B show: the colibacillary form that is grown on the culture medium that contains this invention compositions changes.Figure 58 A shows: colibacillary normal morphology is a rod-short.On the contrary, in colibacillary the 5th, six generations that are grown on the culture medium that contains this invention compositions, be longer, bigger shaft-like or essentially continuous fine thread shape (Figure 58 B).

Figure 59 A and B show: the morphological variation that is grown in the bacillus pyocyaneus on the culture medium that contains this invention compositions.Figure 59 A shows: the normal morphology of bacillus pyocyaneus is a rod-short.On the contrary, in the 5th, six generations that are grown in the bacillus pyocyaneus on the culture medium that contains this invention compositions, be various longer shaft-like or essentially continuous fine thread shapes (Figure 59 B).

These results have determined that this invention compositions has in the ability that does not cause the form that makes antibacterial under the directly dead situation of cell to morph.These cells still continue genetic copying takes place, and obviously can also change the aggressivity of antibacterial.This binding mode and those utilize antibiotic completely different in the mode of transcribing with translating phase inhibition genetic copying gradually.

In order to confirm that the present composition not only causes the morphological variation of antibacterial also to change its toxicity, carries out experiment in vitro to test the influence of this compositions for the plasma-coagulase of staphylococcus aureus.Shown in the form of Figure 60, the cell culture of matched group has the enzymatic activity of height, and the liquid that contains many macrocolonies is limpid.On the contrary, the enzymatic activity that is grown in the cell in the culture medium that contains the present composition is weakened gradually.Be passaged to for the 7th, eight generations, less petite in the culture of muddiness, occurs.Shown in Figure 61, show for the present composition of different content, antibacterial has a different dose response.When content was low, antibacterial need reduce the activity of plasma-coagulase with the long time.

The present composition is determined the influence of the propagation of staphylococcus aureus and bacillus pyocyaneus.Shown in Figure 62, after this antibacterial of two types was passaged to for the tenth generation, total number of bacteria had reduced 20-30 doubly.

Although after the quantity of bacterial cell, was used this inventive compositions treatment less than significantly reducing, the aggressivity of antibacterial had obviously been weakened.Shown in Figure 62, the pathological examination of animal has shown this difference equally.In the subcutaneous tissue of control animals, hyperemia, edema, inflammatory cell infiltration and suppuration appear, show the infection fully that staphylococcus aureus is arranged.On the contrary, in by subcutaneous tissue of the animal of bacterial infection and striped muscle, there is the infiltration of a little inflammatory cell of the phenomenon of not suppurating.

As mentioned above, this invention compositions that contains sterols in vegetable oil not only can make the form of antibacterial that obviously variation takes place, can also kill bacteria, weaken toxicity and the aggressivity of antibacterial significantly.Equally, in animal and clinical trial that the compositions that this is contained sterols is carried out, antibacterial is inhibited significantly to the toxicity of wound surface, and regenerated new zooblast can with the antibacterial mutual survival, but and ramp repair rapidly and neomorph to guarantee intravital tissue.

The inventor believes, different bacterial cells is for the different reaction that combines of sterols and the cell membrane of antibacterial.The composition of film and mobile difference may cause the differential responses aspect morphological variation and cell cycle between eukaryotic cell and the prokaryotic cell.

In prokaryotic cell (for example antibacterial), the division of DNA and cytoplasmic division directly combine.When dna replication dna, the chromosome of double copy is connected the special area of cell membrane, and is separated gradually by the growth between cell membrane.Separate occurring on these two attachments, each daughter cell obtains a chromosome like this.

Gram negative bacteria (as escherichia coli) has two-layer cell membrane: inner membrance and adventitia.Have between the inside and outside liquid bimolecular film highly porous infiltration, firm by protein with constitute the poly-enzyme of peptide of the polysaccharide of bacteria cell wall; Combine with lipoprotein at the poly-enzyme of adventitia peptide, be packed in the gap of pericentral siphon.Various soluble protein molecules are also contained in this gap.Gram positive bacteria (as staphylococcus and streptococcus) has the cell monolayer film, but thicker cell wall is arranged.The inner membrance of their monofilm and gram negative bacteria is similar.

The cell membrane of antibacterial is made of lipid bilayer, and this is the basic architecture basics of cell membrane.The lipid of cell membrane is an amphiphatic molecule, and is water insoluble but easily be dissolved in the organic solvent.The cell membrane of about 50% most animals is made up of them, and remaining nearly all is a protein.Cell membrane is rich in phospholipid, and phospholipid has the tail end of polar top and hydrophobic Hydrocarbon.Tail end is fatty acid normally, and they are different on length (containing 14-24 carbon atom normally).The position of the difference of length and fatty acid tail end is important because they influence the ability that phospholipid molecule fills mutually, and because this reason they influence the flowability of film.

Lipid bilayer is two-dimentional liquid structure, and single lipid molecular is freely spread in lipid bilayer.The flowability accurately of cell membrane has important biological significance.For example, when the viscosity of this bilayer strengthened above base level, the transportation and the enzymatic activity of visible film were terminated.The flowability of lipid bilayer depends on its composition and temperature.The temperature of antibacterial, yeast and other microorganisms fluctuates with the environment of the fatty acid composition of the cell membrane lipid that is fit to them, to such an extent as to keep a metastable flowability.

Eukaryotic cell membrane especially contains a large amount of cholesterol---and each phospholipid molecule has a cholesterol molecule.The cholesterol molecule has the effect of the permeability barrier performance of strengthening lipid bilayer.The hydroxyl near the phospholipid molecule polar end of their application self is determined the position in bilayer; The influence of their firm plate-like steroid rings and partly fixedly those on the hydrocarbon chain and the immediate zone of polar end.The activity of the CH2 base by reducing first minority phospholipid molecule hydrocarbon chain, cholesterol makes lipid bilayer not yielding in this zone, thereby weakens the permeability of bilayer to little water soluble molecules.

Most eukaryotic cell membrane are different, not only aspect a large amount of cholesterol that comprised, are also containing on the different mixture of phospholipids.There are four kinds of main phospholipid to take advantage in the cell membrane of many mammal cells: lecithin, sphingomyelins, phosphoric acid acyl serine and PHOSPHATIDYL ETHANOLAMINE.

On the contrary, the cell membrane of antibacterial is made up of the main phospholipid of a class usually, and does not contain cholesterol.The mechanical stability of these cell membrane is to be strengthened by lining cell wall outside.Like this, zoosterol class (as cholesterol) and phytosterol (as sitosterol) combine and change the normal composition and the structure of bacterial cell membrane, cause flowability and permeability to change.It may be the result that flowability changes that the division of antibacterial is suppressed, and represents the growth situation of cell huge or that be elongated under the unabated situation of dna replication dna.

In addition to virus, cold virus for example, hepatitis viruss etc. are also observed and are obtained identical result.

Unique mechanism of this utilization sterols can be used to be formed in the novel antibacterial composition of extensive use in medicine, nutraceutical, cosmetics and the family daily necessity (as collutory, toothpaste or dentifrice), and can not resemble and often have side effects the antibiotics.
