In Vitro Production of Germ Cells from Stem Cells: Hypes and Hopes

Several lines of evidence have reported that mouse ESCs can successfully differentiate into primordial germ cells (PGC) as well as into mature male and female gametes. Human ESCs and adult stem cells (ASCs) can also differentiate into PGCs. Differentiation of ESCs into germ cells of various stages seems to be a spontaneous and quick process, probably due to the nature of ESCs themselves and the...

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 (...

I-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...

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...
