It leads to violation of renewal of tissues, including tissues of endocrine organs, at people over 35-40 years old. Artificial formation of the chimeral individual may be used for recovery of the pool of pluripotent stem cells in patients older than 40-50 years old. Transfusions of mononuclear fraction of peripheral blood procured from young donors 18-23 years old with the same blood groups and sex as the recipient (patent of the Russian Federation № 2350340), allows people over 40 years old to reestablish the pool of pluripotent stem cells, the process of tissue renewal and the production of sex hormones, and can also be seen as a promising way to reduce biological age, while providing a significant prolongation of life and while maintaining a high quality of life. Transfusions of mononuclear fraction of peripheral blood are required to be carried out multiple times before the restoration of the numerical strength of the recipients' pool of pluripotent stem cells is complete. The effectiveness of regeneration reconstitution in individuals older than 40 years old upon receiving transfusions of allogeneic pluripotent stem cells depends on the difference in age between the recipient and the young donor. When there is a major difference in age between young donors and recipients over 40 years old, the proliferative potential of pluripotent stem cells of donors (their ability to maintain the number of own pool) is higher than the proliferative potential of the recipient. In response to the formation of colony-stimulating growth factors, this leads to the dominance of transfused and formed colonies in the bone marrow of the donor's pluripotent stem cells over the analogous cells of recipients when renewing all of their tissues. The latter occurs mainly due to the donors' stem cells.","PeriodicalId":53626,"journal":{"name":"Journal of Stem Cells","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34814735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In every individual there are certain cells and signaling networks which work together to proliferate the desired tissue lineages to replace the dead, lost and injured counter parts. This homeostasis mechanism keeps functioning of the organ system intact. There are some tissues such as skin, gut, blood, respiratory tract, uterine endometrium, testis must perpetually renew the majority of cells. As the aging advances the turnover potentials decreases under normal circumstances, some of these respond inefficiently to regenerative pressures (eg: brain and heart) while other respond quite well. Therefore creating an optimized micro environment using external means through non-invasive or invasive procedures preferably minimally by utilizing appropriately subjected stem cells/stem cell secretome to induce regeneration at the target sites where it does not take place spontaneously.Stem cell biology is one of the most attractive areas of biomedical research, as emerges for the execution of biotechnology towards the regenerative medicine continues to expand. The presumed potential of the stem cell populations with clonogenic capabilities are harnessed for the therapeutic applications.

The various regulating factors at different levels of RBCs production are being explored. Since most of the ex-vivo erythropoiesis protocols mimic the dogma followed by hematopoietic stem cells in vivo to give rise to mature RBCs which essentially deals with the intermediate stages of erythropoiesis such as burst forming unit-erythroid (BFU-E) and committed erythroid colony forming unit-erythroid (CFU-E). In vivo generation of erythroid progenitors (BFU-E/CFU-E) is essentially controlled by several factors including glucocorticoids, inflammation, and stress. Furthermore, regular production of functionally mature /transfusable units of RBCs is possible only through the coordinated regulation of terminal proliferation and differentiation of erythroid progenitors by external signals, such as erythropoietin, SCF, IL-3 and interaction to extracellular matrix protein(s) in a 3D culture system. We discuss these complex intracellular networks of coordinated factors and try to understand their molecular mechanism through gene regulation by transcription factors, and miRNAs that might be helpful in developing the optimal RBCs production protocols for commercial production.","PeriodicalId":53626,"journal":{"name":"Journal of Stem Cells","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34815204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cell-precursors (progenitor cells) and differentiated cells can be divided a limited number of times and aren't capable of ensuring regeneration of tissues during the whole process of ontogenesis. The renewal of tissues during the whole long period is impossible without the participation of a specialized system which is responsible for regeneration. The given system is made up of pluripotent stem cells which are capable of differentiating themselves into all types of somatic cells, and into a line of genital cells. These stem cells are also capable of reproducing themselves over the whole lifespan of the organism. The participation of pluripotent stem cells and the possible mediation of antigen-presenting cells and T-helpers/T-suppressors in the complex with molecules of the MHC I class/II class make it possible to consider that exactly this immune system is responsible for regeneration of tissues in the organism. The participation in the regeneration process is the most important (and perhaps the leading) function of the immune system. With age the quantity of pluripotent stem cells gradually decreases. It leads to violation of renewal of tissues at people over 35-40 years old. Transfusion of mononuclear fraction of peripheral blood procured from young donors 18-23 years old with the same blood groups and sex as the recipient (RF patent number 2350340), allows people over 40-50 years old to reestablish the pool of pluripotent stem cells and the process of tissue renewal.","PeriodicalId":53626,"journal":{"name":"Journal of Stem Cells","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34814730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
