Definitions
- the subject of the present invention is a preparation resulting from an in vitro culture of non-elicited dedifferentiated Argan cells, a cosmetic or dermatological composition comprising said preparation and its uses for the treatment of cutaneous aging, inflammation and cicatrization. .
- the Argan tree is a tree that belongs to the botanical family of Sapotaceae and bears the scientific name Argania spinosa (L.) Scelles.
- the Olivier its trunk is short, tortuous.
- the wood is very hard and dense.
- the twigs are very spiny and have small, lanceolate leaves, alternate, narrow, short (about 2 cm) and often grouped into fascicles.
- the leaves are evergreen, but during a severe drought they become deciduous and fall.
- the flowers are hermaphrodites and pentamers. They are grouped in glomerulus, blossom in May of June. They are greenish-green in color.
- the fruit is a sessile berry, yellow, oval, 4 to 5 cm long. It consists of a pulp containing a false core consisting of 2 to 3 flattened seeds welded together and each containing an oleaginous kernel.
- the Argan tree is endemic to Morocco and located mainly in southwestern Morocco between Essaouira and Agadir.
- the argan plantation covers approximately 830 000 ha.
- TheIch populations first exploited the Argan tree for its particularly hard wood as fuel supply.
- the other great traditional use is the oil extracted initially manually but today mainly using press.
- the first one use of this oil is food; today, it is experiencing a significant exploitation in cosmetics. Residual pulps and cakes from this oil production are normally fed to animals.
- Cosmetology has developed many products from the Argan tree. Seed oil has been the subject of several invention patents: oil obtained by solvent (Patent FR 2,553,788), argan oil enriched in unsaponifiable (Patent FR 2,724,663).
- Substances other than oil have also been patented. This is the case of peptides from seed cakes obtained after extraction of the oil: combination of oil and peptide cakes for the treatment of disorders related to skin aging (Patent FR 2 756 183).
- the Argan tree as a whole therefore has a composition of interest for a dermatological and / or cosmetic use.
- Argan is an important plant resource, from an ecological point of view first of all because it is an "ecosystem" plant. Perfectly adapted to aridity, it protects the soil from water and wind erosion and thus opposes the advance of the desert in Morocco. But also from an economic point of view, because it is a tree with multiple uses.
- Another way to obtain molecules of interest from a plant is the preparation of totipotent dedifferentiated cell cultures.
- the use of dedifferentiated plant cells also makes it possible to avoid certain problems of industrialization encountered during the development of cosmetic products. Indeed, with cell culture, the difference in concentration of interest substances that exists between different batches or crops of the plant disappears. It is also a non-destructive technique and its implementation is relatively simple and inexpensive. Finally, it frees itself from extraction, the cells being in a culture medium, and the active compounds are found either in the culture medium or in the intracellular fluid. Simple grinding therefore makes these compounds available.
- the patent application WO03077881 describes a composition for topical application containing at least one dedifferentiated plant cell broth and elicited in vitro culture to synthesize at least one phytoalexin.
- the plant material is preferably from the vine.
- the Applicant has demonstrated that a preparation, resulting from an in vitro culture of dedifferentiated but non-eluted Argan cells, has good cosmetic and / or dermatological activities in the fields of anti-aging, inflammation and scarring.
- the results obtained demonstrate that, in the specific case of the Argan tree, another enhancement of cell cultures of Argan tree, here not elicited, is possible in the aforementioned axes.
- the application WO03077881 cites various ways of conducting this elicitation, for example UV light for 3 days; carbon dioxide for 24 hours to 2 days; UV ray and carbon dioxide for 5 days.
- the method carried out in the context of the present invention consisting in cell dedifferentiation from plant material derived from argan tree, then in the culture of cells in suspension; allows to quickly obtain a fine, abundant, homogeneous and sterile biomass of this plant.
- the cell culture makes the biosynthetic pathways of this plant manipulable directly at the cellular level.
- the present invention therefore aims at a preparation resulting from an in vitro culture of non-elicited dedifferentiated Argan cells, a cosmetic or dermatological composition comprising said preparation and its uses in cosmetology and / or in dermatology and more preferentially for the treatment of cutaneous aging. , inflammation and scarring.
- the plant cells in suspension are in a state of dedifferentiation similar to that of stem cells for animal cell cultures. These plant cells are theoretically capable of producing all the metabolites observed in the whole plant. Dedifferentiation leads to a disruption of genetic or epigenetic biosynthetic pathways, so that the chemical profiles are quantitatively and qualitatively different between the whole plant and the resulting cell strains. Thus theoretically unreacted reaction intermediates in the whole plant may appear in a cell suspension. This offers new wealth and allows access to a chemical biodiversity "dormant".
- One of the objects of the present invention relates to the preparation resulting from an in vitro culture of non-eluted dedifferentiated cells of Argan.
- dedifferentiated plant cells any plant cell having no particular specialization character, that is to say in a physiological state close to the meristematic tissues of the plant in its natural state. These cells are able to live on their own and not in dependence on other cells.
- the dedifferentiated cells of Argania spinosa are obtained from living plant material taken from the tree or young shoot, be it the leaf, the petioles, the stem, the bark, the root, the fruit, the seed, the flower and its organs or the bud, especially from leaf.
- the method for obtaining the dedifferentiated cell culture is obtained in vitro by any method known to those skilled in the art, reference may be made for example to: Murashige, T., Skoog, F. 1962.

- the average yield is 30 mg of freeze-dried supernatant per g of fresh biomass.
- the antioxidant activity studied in this test represents the ability to specifically trap superoxide anions by chemiluminescence.
- the freeze-dried biomass prepared according to Example 2a and the freeze-dried ground biomass supernatant prepared according to Example 3 have an activity with respect to the generally equivalent radical scavenging.
- Free radicals whose production is increased following external aggressions (cold, pollution, tobacco, UV) are responsible for the alterations of the DNA of the cutaneous cells, but also of the cellular and mitochondrial membranes. These free radicals play a very important role also in the process of inflammation. These highly reactive metabolites are second messengers of cellular stress signaling oxidative and therefore early mediators of inflammation (A. Van Der Vliet et al., Chem Biol Interaction 85: 95-116 1992). The anti-radical activity of the preparations described in Examples 2a and 3 make it possible to combat intrinsic and extrinsic skin aging and against inflammation.
- Extracellular matrix is a dynamic structure with a structural and regulatory role for tissues. It gives the skin its turgidity and its mechanical properties. At the level of the epidermis it occupies the intercellular space and plays a role of maintenance for the epidermal edifice. It also exchanges between cells of the epidermis and plays a role in cell activity. It consists of fibers, including collagen and basic substance (water, salts, glycoproteins, glycosaminoglycans). Collagens are fibrous proteins, formed of three identical or different polypeptide chains connected by covalent and hydrogen bonds. Collagens constitute the essential component of the fibrous network and play a mechanical role conferring resistance and elasticity of the skin.
- MMPs matrix metalloproteinases
- the activated enzyme is pre-incubated with the various preparations and placed in the presence of the substrate.
- the enzyme cleaves the peptide separating the Mca (7 methoxycoumarin-4-yl) acethyl fluorophore from the Dpa (N-3 - (2,4-dinitrophenyl) -L-2,3-diaminopropionyl quencher).
- the peptide then emits fluorescence with a wavelength of 405 nm when excited at 320 nm.
- the enzymatic activity of MMP-1 is measured and is proportional to the fluorescence emitted.
- the supernatant prepared according to Example 3 inhibits the MMP1 activity significantly and dose dependent from 60 to 500 g / ml.
- Table 3 Freeze-dried ground biomass supernatant (prepared according to Example 3), results of inhibition of MMP1 in percentage (%).
- Example 2a The lyophilized biomass prepared according to Example 2a was tested at 60 to 1000 g / ml. Due to physico-chemical interferences of the biomass as a whole, we could not measure the inhibitory activity. However, a very close extract having been tested showed significant inhibitions of 60 g / ml to 1000 g / ml.
- the extract prepared according to Example 3 makes it possible to combat the increased activity of MMPs during senescence and to contribute to the preservation of the mechanical role of collagen, conferring resistance and elasticity on the skin.
- TGF- ⁇ Transforming Growth Factor-beta 1
- TGF- ⁇ belongs to the super-family of TGF- ⁇ , which are secreted by different cell types and play an important role in the control of cell growth and the regulation of multiple cellular responses. and biological processes.
- the cytokines of this super-family have the following major activities: they modulate the proliferation of most cells, they stimulate the proliferation of fibroblasts, they increase the formation of the extracellular matrix (Lawrence, 1996).
- TGF- ⁇ is involved in wound repair and healing processes (Cullen et al., 1997), notably by inducing a reorganization of the cellular cytoskeleton (actin) and by promoting the migration of epithelial cells (Boland et al. ., 1996).
- the most represented cell population in the cutaneous tissue is the keratinocyte population. It is an important source of growth factors that can regulate and influence the behavior of dermal cells: fibroblasts (Ghahary et al., 2001
- Non-elite biomass production according to example 2a Elicited biomass preparation
- BAP 6-benzylaminopurine
- BAP N- (phenylmethyl) -7H-purin-6-amine
- Acetylsalicylic acid and methyl-asmonate resulted in elicitation EMS medium (see Table 4)
- the elicited culture was then maintained for 15 days on a stirring table at 115 RPM in the dark at 29 ° C.
- the fresh biomass is then harvested and drained on a Buchner funnel before being crushed, centrifuged and the supernatant stabilized by lyophilization.
- EMS medium which is the modified Murashige & Skoog medium used for the cultivation in elicited condition of Erlenmeyer suspended argan cells.
- the HaCaT keratinocytes are treated for 5 hours with the various extracts, and the cells are then incubated for 24 hours in DMEM at 37.degree. TGF- ⁇ is assayed in the culture supernatants with an ELISA kit.
- the effects of the non-elite argan biomass prepared according to Example 2a and of argan biomass obtained after elicitation, on the synthesis of TGF- ⁇ in HaCaT human keratinocytes are illustrated in the attached FIG.
- Wound healing is a complex and dynamic biological process that involves the interaction of many local and systemic factors in normal tissue repair. Progression of healing has four interrelated phases: hemostasis, inflammation, proliferation and remodeling. Proliferation involves three observable processes: granulation, contraction and re-epithelialization.
- Macrophages are constantly releasing chemotactic factors and growth factors. Fibroblasts build the new cell matrix necessary for cell growth at the bottom of the wound. This scaffold promotes cell migration.
- the contraction of the wound is a mechanism for reducing the size of the wound and the fibroblasts play a leading role in this contraction.
- Re-epithelization is the regeneration of an epidermis that covers a wound to form an effective barrier against the external environment, capable of pigmenter and regain its sensory and immune functions. It therefore involves the cellular processes of migration and proliferation of keratinocytes, but also the differentiation of this neoepithelium and the restoration of a basement membrane that reconnects the dermis and the epidermis.
- a wave of cellular mitosis occurs to fill the spaces left by the migration and provide cells for the epithelial tissue in three-dimensional regeneration. .
- the proliferation steps of keratinocyte cells, fibroblasts or endothelial cells can be considered as one of the functional phenomena testifying to the healing activity of an active ingredient.
- An increase in the proliferation of fibroblasts or endothelial cells would participate in the healing of the dermis, while the increase in the proliferation of keratinocytes would participate in re-epithelization.
- the technique used makes it possible to measure the incorporation of a thymidine-like nucleotide, 5-bromo-2'-deoxyuridine (BrdU) into the DNA of the S-phase cells.
- the keratinocytes isolated from cutaneous surgical waste, are cultured in complete KSFM (BPE: 25 g / ml, EGF: 1.5 mg / ml). The cells are incubated in the presence of the molecules to be evaluated for 48 h at 37 ° C., in an atmosphere containing 5% CO 2.
- the incorporation of BrdU proportional to the rate of cell proliferation, is evaluated by a system of anti-BrdU antibodies coupled to peroxidase.
- the addition of a peroxidase substrate develops a color reaction (Biotrak Elisa System).
- the corresponding absorbance (OD) is measured at 450 nm. This data is therefore proportional to the cell proliferation rate.
- the percentage of proliferation is then determined according to the formula:
- Min indicator cells incubated with minimum medium
- the min Control corresponds to the 0% proliferation
- the max Control to the 100% proliferation.
- FIG. 2 illustrates the effect of argan biomass prepared according to example 2a on the proliferation of human keratinocytes.
- the protocol used for the study of cell migration is based on the use of a 96-well kit.
- the principle of this test is to study the migration of cells to the well center (96-well plate).
- a stopper is placed in the center of each well, to create a detection zone of 2 mm in diameter.
- the HaCaT cells are then seeded around this stopper.
- the stoppers are removed once the cells have adhered to the surface around them, and thus the cells can migrate to the detection zone. Plates without stoppers and with active ingredients are incubated at 37 ° C for 24 hours in DMEM 0% FCS.
- the quantity of cells located in the area where there was the stopper is then analyzed, in order to evaluate the cell migration.
- the cells are marked with Hoechst 33342 and a cache allows you to view and count only cells in this area. For each condition, the average of 8 wells is achieved.
- IF (0% mig) corresponds to the IF of the wells containing the stoppers and therefore to the background noise.
- FIG. 3 illustrates the effect of argan biomass prepared according to example 2a on the migration of HaCaT keratinocytes.
