The effect of BMP4 on mouse embryonic stem cell proliferation and differentiation into primordial germ cells
Background and Aim: Artificial gamete production from stem cells is a novel strategy for treatment of infertility. Among various stem cell sources, embryonic stem cells (ESC) can be considered as an appropriate source for in vitro formation of germ cells. In this study we evaluated the effect of BMP4 on proliferation and differentiation of mouse embryonic stem cells into primordial germ cells (...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Granulosa cell-germ cell relationship in the developing rabbit ovary.
Granulosa cells play an important part in the nutrition of the oocyte during oogenesis (Raven, 1961). Anderson & Beams (1960) suggested that, in the primary follicle, nutritive material synthesized by the granulosa cells reaches the oocyte by diffusion across the zona pellucida. In the rabbit, follicle formation and elaboration of the zona pellucida begin at the end of the second week after bir...
متن کاملFollistatin288 Regulates Germ Cell Cyst Breakdown and Primordial Follicle Assembly in the Mouse Ovary
In mammals, the primordial follicle pool represents the entire reproductive potential of a female. The transforming growth factor-β (TGF-β) family member activin (ACT) contributes to folliculogenesis, although the exact mechanism is not known. The role of FST288, the strongest ACT-neutralizing isoform of follistatin (FST), during cyst breakdown and primordial follicle formation in the fetal mic...
متن کاملIrinotecan metabolite SN38 results in germ cell loss in the testis but not in the ovary of prepubertal mice
STUDY QUESTION Does the Irinotecan metabolite 7-ethyl-10-hydroxycamptothecan (SN38) damage the gonads of male and female prepubertal mice? SUMMARY ANSWER The Irinotecan metabolite SN38 reduces germ cell numbers within the seminiferous tubules of mouse testes at concentrations that are relevant to cancer patients, while in contrast it has little if any effect on the female germ cell population...
