هدف:اخیرا ماهیت پرتوانی سلولهای بنیادی اسپرماتوگونی (spermatogonial stem cells, sscs) در محیط کشت مورد توجه قرار گرفته است. هدف از تحقیق حاضر تولید سلولهای شبه بنیادی جنینی es-like cells) (embryonic stem like cells, از sscs و بررسی تغییرات مورفولوژیک و ژنتیکی در این سلولها نسبت به سلولهای بنیادی جنینی escs) (embryonic stem cells, است. مواد و روشها: سلولهای اسپرماتوگونی از بیضه موش نوزاد ب...
The possibility to reprogram somatic human cells will greatly and deeply change genetic approach and allow the development of new tools to study genetics diseases. Indeed, our ability to study human genetic diseases suffers from the lack of valid in vitro models. The latter should (i) be originating from human primary cells, (ii) be able to self-renew for a long time and (iii) be able to differ...
objective: mir-302-367 is a cluster of polycistronic micrornas that are exclusively expressed in embryonic stem (es) cells. the mir-302-367 promoter is functional during embryonic development but is turned off in later stages. motivated by the cancer stem cell hypothesis, we explored the potential expression of mir-302 in brain tumor cell lines. materials and methods: in the present experimenta...
backgrounds: a straight-forward way to identify whether a drug or environmental chemical can be harmful to unborn baby is to evaluate its effect on laboratory animals. all invivo methods need large number of animal and are therefore time consuming and expensive. however, the thousands of chemicals in need of testing, to reduce the spending of live animals, an assortment of in vitro assays has b...
objective: pulp and periodontal tissues are well-known sources of mesenchymal stem cells (mscs) that provide a promising place in tissue engineering and regenerative medicine. the molecular mechanisms underlying commitment and differentiation of dental stem cells that originate from different dental tissues are not fully understood. in this study, we have compared the expression levels of pluri...
Stem cells are undifferentiated that can proliferate, regenerate, develop into differentiated cells, and produce a variety of tissues. Embryonic stem adult or somatic pluripotent the three types cells. Another classification is totipotent, multipotent, unipotent cell treatment has possibility treating degenerative disorders, cancer, restoration damaged tissues, all which now have no restricted ...
mouse embryonic stem cells (es) are pluripotent cell lines derived from the inner cell mass of the blastocyst. their properties include self renewal and capacity to differentiate into different cell types. neural differentiation of es cells has been achieved by several different protocols such as treating with retinoic acid and serum decreasing in culture media. the ppars (peroxisome proliferat...
spermatogonial stem cell (ssc) technologies provide multiple opportunities for research in the field of biotechnology and regenerative medicine. the therapeutic use of embryonic stem cells (escs) is restricted due to severe ethical and immunological concerns. therefore, we need a new pluripotent cell type. despite well-known role of germ cells in the gametogenesis, some facts apparently show th...
The Zinc Transporter SLC39A10 Plays an Essential Role in Embryonic Hematopoiesis (Adv. Sci. 17/2023)
Embryonic Hematopoiesis In article number 2205345, Fudi Wang, Junxia Min, and co-workers identify demonstrate indispensable function of zinc transporter SLC39A10 (ZIP10) its mediated homeostasis for maintaining the survival fetal hematopoietic stem/progenitor cells. As most important importer on cell membrane stem cells, ZIP10 functions as a gatekeeper (like vacuum to transport across membrane)...
