Review of Differentiation and Proliferation of Primordial Germ Cells in Culture
Primordial germ cells (PGCs) are highly specialized cell population that arises from the epiblast in vivo. There are three critical steps in the life cycle of these cells: 1-Specification 2-migration and proliferation 3-prenatal and postnatal sex specific development. Specification of germ cells in epiblast occurs due to signals secreted from extraembryonic tissues. Primordial germ cells are re...

متن کاملI-18: The Role of Sex Chromosomes in Female Germ Cell Differentiation
Background When gonadal sex reversal occurs in mammalian species, the resultant XX males and XY females become infertile or subfertile, suggesting critical roles of sex chromosomes in germ cell differentiation. The objective of our study is to clarify the mechanism of infertility in the B6.YTIR (XY) sex-reversed female mouse, which can be attributed to a failure in the second meiotic division i...
متن کاملI-51: The Role of the Transcription FactorGCNF in Germ Cell Differentiation and Reproductionin Mice
The germ cell nuclear factor (GCNF) is a member of the nuclear receptor super family of transcription factors. GCNF expression during gastrulation and neurulation is critical for normal embryogenesis in mice. GCNF represses expression of the POU domain transcription factor Oct4 during mouse post-implantation development in vivo. Oct4 is thus down-regulated during female gonadal development, whe...
متن کاملThe 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 (...
