Description

Leukocyte cell banks
Technical field
The present invention relates to new leukocyte list and adopt form (isolating leukocyte list is adopted), implement the method and apparatus that isolating leukocyte list is adopted, consequent leukocyte cell banks (leukocyte cell bank) and the various forms of treatments of carrying out based on them.
Background technology
Cell bank
The cell bank industry is a kind of service occupation, and it is preserved living cells for future use.This industry has many decades history, for example stores the spermatid of cattle so that cow is carried out the artificial fertilization.
Along with the technological progress of biomedical research and field of tissue engineering technology, people recognize that carrying out multiple alternative medicine with human stem cell has multiple probability.These progress cause more and more needing to separate the stem cell of individuality the facilitated method of also frozen standby (using from body).For example, increasing people has recognized that this class stem cell preservation thing increases fast in the privately owned cell bank of result to storing the demand of umbilical cord hemocytoblast.
Along with the demand of pair cell and tissue constantly increases, the cell bank industry is recognized practical problem gradually.Known at present, the cell bank that aims to provide long-term cell source is easy to be subjected to stochastic events, cause part or all to preserve thing and lose activity, and cell bank is big more, and period of storage is long more, and the risk relevant with this random event is just big more.The integrity of preserving thing is also most important: preserve the decisive action that integrity that preparation, preservation, operation and the occupation mode of thing might the pair cell storehouse plays key: this point, for the cross-contamination of preserving thing can cause transmission of disease cause improperly or dangerous physiology consequence (as, might be owing to when autotransplantation, given the allos cellular material) situation be even more important.For bigger cell bank, information storage, processing and preservation thing classification catalogue also are extremely important.
This class problem makes many countries put into effect increasing laws and regulations, manage cell bank generation, keep and use: at present in Britain, the cell bank industry is by an integrated management organizational controls.
Should acute autotransplantation (CAT) therapy
Recently document description has been arranged a kind of therapy (seeing WO 00/29551 and WO 01/88099), it takes out various tissues (comprising leukocyte) from healthy, they are stored in tissue or the cell bank, when in the future some day emergency taking place and to carry out autotransplantation, can carry out autotransplantation with them.This therapy is referred to herein as should acute autotransplantation (contingent autologous transplantation, CAT) therapy.
For any concrete tissue or cell type, only some healthy population may need the CAT therapy.Therefore, the CAT therapy whether effectively, key depends on whether can produce comprehensive type cell tissue storehouse, comprise the preservation thing from most of people in this colony in the described storehouse.
Therefore there is viewpoint to think, will helps the CAT therapy by making up comprehensive tissue bank.But the character of CAT therapy itself has determined it that any this class tissue bank is had its unique and strict requirement.Particularly, the CAT therapy require to have a large amount of blood donors to participate in (thereby a large amount of preservation things are arranged), relatively long storage life arranged, in long-time well maintained tissue function and in final treatment application, excellent adaptability is being arranged.
For leukocyte cell banks, these problems are especially urgent, because the absolute quantity of the cell that leukocyte cell banks can provide is fewer, the function that might key depends on a small set of cell is renderd a service in final treatment, and because different cells adapts to storage by different way, the leukocytic activity of storage might change as time passes.Up to now, still nobody constructs the leukocyte cell banks that is fit to CAT.
Adopt the leukocyte that separation can be used for the CAT therapy by the leukocyte list
The leukocyte list is adopted the blood sampling art (apheresis) that (Leukapheresis) is a kind of specific form, relates to from the blood that obtains Selective Separation and takes out leukocyte, and the remainder with blood feeds back to the blood donor then.Adopt in the process at the leukocyte list, the blood flow that makes taking-up is through cell separation apparatus, and this device will have nuclear leukocyte and erythrocyte and separating plasma external.Erythrocyte and blood plasma are fed back to the blood donor, and this also is the part of separation process.This process is carried out continuously, constantly has blood to be removed and almost is to turn back in the body after having carried out various extractions simultaneously.Therefore, the leukocyte list is adopted and is made and whole blood of blood donor might be taken out several times and feed back, and isolates and preserve a large amount of leukocyte under the situation that does not injure this person.This technology thereby depend on and can set up a kind of vein to the venous extracorporeal circulation of blood, and from this circulation blood, extract leukocyte.
It generally all is automatic that the leukocyte list is adopted, centrifugal or filtering technique carries out with fluid successive or that be interrupted, can be referring to " Leukapheresis and Granulocyte Transfusions ", by AmericanAssociation of Blood Banks, Washington DC (1975) publishes.
Implement device description to some extent in US 3489145 and US 3655123 that centrifugal leukocyte list is adopted, implement device description to some extent in US 3802432 and US 3892236 that filtering type leukocyte list is adopted.Gravity type leukocyte list is adopted (gravity leukapheresis) and is only utilized gravity to implement leukocyte separation and collection, and this method is described in US 4111199 to some extent.
The automatic leukocyte list device for picking that can be purchased at present has number of different types, comprise: FenwalCS-3000 (Baxter Healthcare, Chicago, IL), Cobe 2997 (Cobe BCT, Lakewood, CO), Cobe Spectra, Cobe 2991, and Haemonetics V50 (Haemonetics Corp., Braintree, MA).Wherein any may be used to the present invention for this, but preferred Cobe  system (CobeBCT, Lakewood, CO, USA), it can extract the 40%-50% of total white blood cells from the whole blood of its separator of flowing through, and the flow velocity of its per minute can reach 40-60ml or bigger.
The someone proposes in the recent period, adopts with the leukocyte list and creates the used B lymphocyte repertoire (seeing WO00/29551 and WO 01/88099) of CAT therapy.But adopt the restriction that the business-like comprehensive type B lymphocyte repertoire of generation is subjected to blood donor's convenience and comfortableness with the leukocyte list.For example, the blood donor is limited at time that blood collection mechanism carries out blood supply of can visiting usually.Therefore, in a single day the blood donor arrives blood sampling mechanism, and it is a key factor in Blood Sampling Room institute's time spent really.But the leukocyte list is adopted generally needs 2-4 hour (than the required time long number of the blood that a unit is provided doubly).Bring the problem of blood donor's comfortableness thus: a lot of people feel to fear very much when seeing real blood collection procedure, and the blood donor must insert (normally two at a syringe needle on one's body at least in whole process, be used for drain and feed back blood), bring potential danger thus.
Therefore, need a kind of method for preparing leukocyte cell banks, it can avoid the problem that occurred when using the leukocyte list to adopt, can also make blood donor more convenient (and sense of discomfort is less), thereby might create the comprehensive type leukocyte cell banks that is applicable to the CAT therapy.

Similarly, term " isolating blood sampling art " is meant a kind of new model of isolating blood sample being implemented the blood sampling art with in this article.
Term " isolating blood sample " is with in this article, is meant and provides the blood sample that does not have fluid communication between blood donor's the blood of this blood sample.Therefore leukocyte list device for picking and provide between the individuality of this blood sample and do not have fluid communication and/or residue blood sample not to be fed back in this individuality body, isolating blood sample is provided in the process that isolating leukocyte list adopts.
Term " autotransplantation " is meant isograft or self-transplanting with in this article, and wherein term " from body " is used for expression, and transplanting is the transplanting of carrying out to the identical biology that cellular material (for example leukocyte) is provided (being same individual)." transplanting " is meant any relating to the process in cellular material (for example leukocyte) the introducing biology, so this term comprises any type of transplanting known in the art.
Term " dormancy " is meant any dormant state or resting state with in this article, and the method that reaches this state is known in the art, and description is hereinafter arranged.Any known method comprises the profound hypothermia preservation, can use.Therefore, leukocyte can maintain quiescent condition, non-activity state or nonproliferative state.
Term " health " uses with blood donor's individuality in this article, represents that this individuality does not have leukocyte defective (according to the definition of this paper).Therefore, term " health " comprises blood donor's individuality of non-disease conditions at this paper, and this blood donor's individuality is in the state of any symptom (that is, being asymptomatic or subclinical performance) of not suffering from any disease or imbalance or not showing described disease or imbalance.Especially, term " health " comprises not suffering from blood donor's individuality of the symptom of wanting the disease for the treatment of by Method for autologous transplantation subsequently or not showing described disease in this article.
II. Blood sample
The present invention can be applied to any type of blood sample, as long as: (a) this blood sample is the isolating blood sample according to above-mentioned definition, and (b) this blood sample comprises at least a portion leukocyte of blood donor's individuality.
Can before being applied to method of the present invention, blood sample carry out various processing to it at external (ex vivo).For example, usually before use with blood sample cold preservation (chill).Other processing can comprise adds preservative agent and/or anticoagulant.
Also can before blood sampling or during the blood sampling various preparations be applied to blood donor's individuality, thereby at blood sampling pre-treatment blood sample.
Can see hereinafter the chapters and sections that are entitled as " leukocyte processing " for details at the example of processing external and/or that use in vivo.
General preferably gather 450-500ml blood at least from blood donor's individuality, this is equivalent to the blood volume of (UK blood transfusion service) unit that the blood donor provided in Britain's blood transfusion service.As possible, (for example, 2-3 is in week, in preferred 2-3 month or in 6 months or in 1 year, in 2 years or in 3 years or in the longer time) repeatedly blood sampling (for example, a plurality of 450-500ml) in a period of time.In these blood samples one or more can be divided into or be mixed into a plurality of leukocyte cell banks and preserve things.Only in Britain, annually collect the blood that surpasses 300 ten thousand units from the blood donor, it is very usual that the blood that therefrom takes out a unit is used for allograft.
The blood that takes out is very fast can be replenished (replaced), therefore can repeatedly gather the blood of a unit in 1 year from blood donor's body, in case of necessity, gathers 2-12 unit, and individual harmless to what taken a blood sample.
III. Select blood donor's individuality
General consideration
Restorative autotransplantation is that a kind of possible definitive application is in the therapy of any individuality.Therefore, the present invention can be effective to prepare the complete leukocyte cell banks that comprises Different Individual as much as possible, so that can carry out restorative autotransplantation to any specified individual whenever necessary.
For these reasons, consider the present invention is used as far as possible widely, so that can set up complete leukocyte cell banks.But depend on (being somewhat dependent upon at least) this blood donor's individuality in the health status of donating blood at that time because each part preserved the quality of thing, so the blood sample that is preferred in the inventive method is gathered from healthy is individual.
Also have other factors also to influence selection to the blood donor: for example, the blood sample that is used for the inventive method is preferably gathered more favourable when blood donor's individuality is still young, preferably at adolescence (adolescence) or grow up early stage (early adulthood).For the people, preferably in the blood sampling (preferably repeatedly blood sampling) of about 12-30 year, preferred 15-25 year.Especially preferably 16 or time blood sampling more than 17 years old, for example, 16-30 year, 17-30 year, or 18-30 year maybe can be 18-35 or 40 years old.Therefore, preferably in the host living beings maturation, or near period of maturation (maturity), but do not obtain its cell before obviously entering aging (ageing) or old and feeble (senescence) process.Especially, comparatively favourable when the immune system maturation of preferred host living beings or zoon.
But, the time that the present invention is also included within beyond the above-mentioned age bracket obtains cell, can obtain cell in any time of firm birth back (post-natal), for example the host living beings from juvenile period (juvenile) obtains cell, for example from the childhood period middle and advanced stage (mid-to late childhood) or even obtain cell from baby (infant), or obtain cell from the individuality of old (older).
From firm birth back or old host take a sample and allow to collect multiple sample, thereby increased the chance of the cell that accumulates sufficient amount.In addition, can cross moral claim (ethical requirements), inform and requirement through agreeing to take a sample as needs from juvenile host or old host sampling.
Preferably from the sampling of adolescence or adult host living beings, because the cell that is obtained, the especially cell that obtains from blood, will comprise the valuable mature T cells of larger proportion, they can discern abnormal cell colony, as cancerous cell or by the cell of viral infection.So, when using blood sample, more favourable from the blood sample that the individuality (promptly not being fetus (foetal) or neonate (neonatal)) with maturation immunity system obtains.
Therefore, the present invention relates to take place in the future or unexpectedly take place or only be purposes the occurrent incident from the individual blood sample of collecting of blood donor, described blood sample is not obtain when blood donor's individuality does not exist the direct indication that may suffer from disease, hint or suspects, and described future, incident was not the disease of having predicted or having suspected or indicated.Therefore, in some embodiments of the present invention, described blood donor's individuality is to any disease specific susceptible, or do not suffer from the danger of any disease specific, for example do not have any the indicate symptom or the performance of disease subsequently.Similarly, host living beings does not preferably suffer any damage that may cause the precognition disease.
In fact, for some application (for example, prepare leukocyte cell banks in order to carry out restorative autotransplantation subsequently), the blood sample that preferred the present invention uses obtained from this individuality before blood donor's individuality is suffered from any disease or related symptoms occurred, was more preferably at host living beings to be in good generally health level, and to obtain during preferably without any the immunocompromised host (immunocompromise) of form.In these embodiments, do not occur disease symptoms in advance or have disease or be diagnosed as suffering from disease and this disease when being the disease that to receive treatment subsequently at blood donor's individuality, that is to say at this host living beings and be in health status and be not that " after being ill recover " state (for example, be not in from the leukocyte defect part ground that will be treated or the state that fully recovers) time, the blood sample advantageous particularly obtained from this individuality.
(Predisposed) blood donor individuality of susceptible
Treatment means is constantly progressive, and also more and more deep to the understanding of lysis, this helps us to adjust orientation treatment, thereby palliates a disease and misery.Such understanding is advanced greatly owing to the technological progress of biology field.We can follow the tracks of the pathogeny of disease now on molecular level, and recognize, individual gene structure plays an important role aspect the susceptibility of some disease at them.For example, we are known, and some are individual because the relation of their genomic constitution is easy to take place some disease.
Disease majority for some individual susceptibles is the leukocyte defective, and this term is represented to use from the leukocytic situation of body in this article.Therefore this class situation comprises: individuality has been suffered from and leukocyte function imbalance diseases associated, infection or disorder, and perhaps having suffered from needs to strengthen or stimulate the active disease of endogenous leukocyte, infection or disorder." example explanation (Exemplary indications) " chapters and sections during the instantiation of leukocyte defective can vide infra.
By gene test, can identify the individuality of those susceptibles at present in leukocyte defective (for example any in the various forms such as cancer, immune dysfunction or infection).
In addition, we are for the cognition of body immune system, and especially for immune system recognition and kill and wound by the cognition of the cell of viral infection and tumor cell, in continuous progress.We are known now, immunity for the activated cell mediation, undesirable cell (offending cell) (for example by the cell of viral infection or tumor cell) must be presented the restricted tumor epi-position of HLA I class or virus epitopes and danger signal such as GM-CSF and/or TNF-α simultaneously, passs interactional with it cytotoxic T-lymphocyte (CTL) group so that immune antigen-presenting cell (APC) is costimulatory signals such as B7 and IL-12 with antigen.This presenting simultaneously causes producing activating cell clone and memory cell is cloned (summary can referring to Nature Medicine Vaccine Supplement 4 (1998) 525).Lacking under the situation of these extra signals, the HLA-I class antigen of identification undesirable cell-restricted T-cell through the processing back by broken ring or desensitization (body a kind of may be used to avoid to take place the process such as disorders such as autoimmune diseases).Inducing of this class tolerance is because nonrecognition (ignorance), anergy (anergy) or physiological disappearance (physical deletion) (Cold Spring Harbour Symp Quant Biol 2 (1989) 807; Nature 342 (1989) 564; Cell 65 (1991) 305; Nature Med 4 (1998) 525).
Clear at present, tumor cell is not automatically presented danger signal and/or costimulatory signal simultaneously.So a large amount of breedings (spawning) of tumor may cause eradicating those T cell clonies that cell-mediated antineoplastic immune power is provided.Therefore, show the patient of cancer, leukemia/lymphoma or sarcoma etc., may lose the ability of their inborn elimination tumor by this mechanism.
But, if before the diffusibility disease takes place patient, required T lymphocyte or its sample are taken out, when morbidity, relevant T cell mass can be returned to this patient so, behind collaborative the stimulation, alleviate disease through necessary T cell.Collaborative stimulation can be carried out when cell is returned to patient, also can carry out after by patient being implemented other treatment cell being returned to patient, perhaps no longer includes other stimulation except the stimulation of the natural generation of this patient.Activation/the stimulation of cell also can be external evoked before feedback is given patient.
The present invention so particularly suitable at susceptible in the case of leukocyte defective growth.Therefore it represented a kind of from the individual leukocyte that takes out of healthy, so that at this individuality afterwards whenever necessary, by transplant a kind of method (means) to this individuality from body (from gene) implantation method.Although this susceptible individual might never be accepted these cells because never the disease that need treat in this way occurs, the present invention also can be used to provide a kind of insurance forms, and the excessive risk of taking precautions against aleucemia for this individuality provides safeguard.
Similarly, do not diagnose out the individuality of susceptibility also can select, before their journey abroad, draw samples is put into leukocyte cell banks of the present invention, for future use.This class is used and can be comprised the treatment of infecting overseas.
In addition, well-known, ageing process makes more susceptible disease of individuality.As if the basic reason of this susceptibility is that the T cell in the ageing process and the number/activity of B cell significantly reduce, and causes immunologic function forfeiture (Mech Ageing ﹠amp; Dev 91 (1996) 219; Science 273 (1996) 70; Mech Ageing ﹠amp; Dev 96 (1997) 1).Disease susceptibility especially is found in elderly patients when accepting such as surgical operation in hospital, and here, they are easy to chance of occurrence and infect, and cause serious or or even fatal consequence.Blood sampling when this class individuality is younger is handled according to method of the present invention, puts into leukocyte cell banks, just can provide restorative autoplastic chance in above-mentioned situation.
This method can more be widely used in the operation back and strengthen patient's immune system, thereby reduces the probability that opportunistic infection causes post-operative complication.Therefore, the present invention can be used as prophylactic treatment, for example, be used for when elderly patients more susceptible in the disease.
IV. Leukocyte
The present invention relates to adopt art with isolating leukocyte list separates from blood sample and collects leukocyte.Be appreciated that the leukocyte list adopt do not need blood sample in the process in all leukocyte all separate and/or take out.Under many circumstances, only take out and/or isolate that the part of total white blood cells just is enough in the blood sample.Those skilled in the art are easy to the leukocytic appropriate amount of determine to need taking out, it based on factor such as isolated leukocytic purposes, sample size, blood donor's state, leukocytic feature and the concrete leukocyte list device for picking that adopted and difference is arranged.
The leukocyte of collecting in the inventive method separates from original blood sample to a certain extent and obtains.Term " isolating " is used for expression in this article, isolating leukocyte be in and be different from their a kind of physical environments the human internal environment, any concrete purity do not represented in this term.In fact, the purity absolute value is also non-key, and those skilled in the art are easy to determine suitable purity based on leukocytic purposes.
Must not represent leukocytic separation and collection in the inventive method yet, preferentially separate and collect the leukocyte of any particular type.Leukocyte of the present invention comprises any leukocyte, such as granulocyte, and lymphocyte and mononuclear cell etc.
Granulocyte comprises myelocyte (myelocyte), basophilic granulocyte, eosinophilic granulocyte and neutrophilic granulocyte.Lymphocyte comprises bone-marrow-derived lymphocyte, T lymphocyte and natural killer cell.Mononuclear cell comprises mononuclear phagocyte and other macrophage.
But the leukocyte that in some embodiments, separates and collect preferably comprises the leukocyte of one or more particular types.Preferred cell type is a lymphocyte, especially T-lymphocyte (T-cell).The special T-lymphocyte of wanting preferred maturity.
Because mature T cells adds up to 1-2.5 * 10 in every liter of human blood 9, so comprise 1-2.5 * 10 in the 100ml blood sample usually 8Mature T cells, generally this just is enough to provide can represent in the whole ripe human T-cell colony and produces the required amount of beneficial effect.But, fraction according to the total white blood cells that separates and collect with leukocyte list device for picking, and the effectiveness of any resuscitation technique that is adopted, preferably use 100ml at least, 115ml, 200ml or 300ml blood sample, more preferably surpass 400 or the blood sample of 500ml, so that when individuality generation disease, can obtain the mature T cells of sufficient amount, after returning this individuality, produce useful therapeutic effect.
Known in the art have the multiple standards technology can select concrete lymphocyte subgroup from the sample that comprises the mixed lymphocytes group.The example of this class subgroup comprises, CD3 +, CD8 +, CD4 +And CD16/56 +(NKT) T cell and CD19 +The B cell.For example, any a group or any mixing or any combination may be used in method of the present invention, purposes and the compositions in this class T cell subsets, they can obtain at an easy rate by multiple known method, described method such as FACS (fluorescent activation cell sorting (Fluorescence Activated Cell Sorting)) and hemocytometer number system (haemocytometrysystems).
The present invention has also found to use widely, and except the leukocyte list is adopted art, also can adopt the separate type blood sampling art of any other form.Therefore, the present invention relates to be used to prepare the separate type blood-sampling method of stem cell compositions (and therefore producing stem cell bank).Therefore the present invention can also be applied to stem cell or progenitor cell (progenitor cell), comprises pluripotent stem cell and has entered the stem cell or the progenitor cell of concrete differentiation pathway.
V. Leukocyte is handled
Can carry out various processing to leukocyte.This class is handled and is caused, for example amplification (expansion) is a part of or representative cell subsets, improve the long-term vigor of leukocyte in the dormant stage, strengthen their treatment potentiality, remedy some or all leukocytic shortages or defective (for example, as in therapeutic autotransplantation treatment pattern) and/or make them safer when being used for autotransplantation subsequently.
Described processing can be carried out (and before or after carrying out autotransplantation) before or after the leukocyte dormancy.In addition, can after sampling, handle (being external carrying out), before making the cell dormancy or after the recovery, can handle.For example, can be, in the autotransplantation process, with a kind of other compositions and leukocyte compositions (sequentially) or use simultaneously successively to leukocytic processing.Can before being about to begin autotransplantation, carry out leukocytic processing.
Perhaps (or in addition) can be before getting blood, by using somatomedin or cytokine etc., in vivo leukocyte still handled (seeing below).
The example of transplanting pre-treatment comprises various genetic modifications, as mixes negative selection marker (for example, referring to W096/14401, it is incorporated herein by reference).This class is handled leukocyte depletion (ablation) or the titration dose-effect curve that makes after might transplanting.Other hereditary intervention can comprise, regulates or modify one or more expression of gene (for example, increasing or reduce gene expression), makes one or more gene inactivation, gene substitution and/or make one or more allogeneic gene expression).Other genetic modification comprises, the concrete T-cell of directional guide (targeting) (is seen W096/15238, it is incorporated herein by reference), and with antibody modification T-cell receptors all constituents (receptor repertoire)/expression, thereby the T-cytochimera produced.
Other processing of the present invention comprises, leukocyte is exposed to one or more stimulation molecule, for example antigen (as cancer antigen or virus antigen), antibody, T cell recognition epi-position, peptide, blood factor, hormone, somatomedin or cytokine or its combination.
For example, leukocyte can be handled with following material at external (or in getting blood before in vivo): antigen (for example, cancer antigens such as prostate specific antigen 1 or prostate specific antigen 2, her-2/new, MAGE-1, p53, Ha-ras and c-myc, or virus antigen), antibody, T cell recognition epi-position, peptide, blood factor, hormone, somatomedin or cytokine or its combination.Stimulation molecule can be synthetic molecule, recombinant molecule, perhaps can be from human body or animal body purification or isolating molecule.The useful especially stimulation molecule of this respect is selected from IFN-alpha, IFN-beta, IFN-gamma, II-1a, II-1b, II-2, II-3, II-4, II-5, II-6, II-7, II-8, II-9, II-10, II-11, II-12, II-13, II-14, II-15, GM-CSF, M-CSF, G-CSF, LT or above-mentioned two or more combination.Such processing can change leukocytic growth and/or activity and/or differentiation state, and/or can be used to distinguish or leukocyte type that Selective Separation or enrichment are required or remove undesired cell.
There are some progress to make recently and can obtain to be used for autoplastic subsequently cell.For example, the research to the hemopoietic regulatory factor causes isolating a series of factors that can influence lymphopoiesis and differentiation.These factors comprise, cytokine is (as interleukin series IL-1 to IL-18, leukotriene, tumor specific antigen such as prostate specific antigen 1 or prostate specific antigen 2, her-2/new, MAGE-1, p53, Ha-ras and c-myc), somatomedin such as TNF, TGF, FGF, EGF, GM-CSF, G-CSF, and other.This wherein has the multiple factor can buy the commodity of clinical use at present, and having some to show can increase peripheral blood lymphocyte greatly, the lymphocytic quantity of especially immature T.They are applied to blood donor's individuality before getting blood, can control of quality and/or quantity (refer to leukocyte hypotype exist quantity and characteristic), and might need not the bone marrow sampling, directly from blood donor's a large amount of required cell of peripheral body results, as immature T lymphocyte.
Other processing before transplanting comprises cultivates leukocyte (or its subgroup).For example, can cultivate leukocyte makes cell number increase.For example, can make passage with methods known in the art.This class is cultivated and can be carried out before the leukocyte dormancy and/or afterwards.
Therefore, comprise at leukocyte under the situation of T cell, can before transplanting, work in coordination with stimulation and/or before autotransplantation, make the T cellular exposure in tumor antigen (optional) with collaborative stimulating factor to the T cell.
