Embryonic germ cells induce epigenetic reprogramming of somatic nucleus in hybrid cells.

Genomic reprogramming of primordial germ cells (PGCs), which includes genome-wide demethylation, prevents aberrant epigenetic modifications from being transmitted to subsequent generations. This process also ensures that homologous chromosomes first acquire an identical epigenetic status before an appropriate switch in the imprintable loci in the female and male germ lines. Embryonic germ (EG) ...

Epigenetic reprogramming in mouse primordial germ cells

Genome-wide epigenetic reprogramming in mammalian germ cells, zygote and early embryos, plays a crucial role in regulating genome functions at critical stages of development. We show here that mouse primordial germ cells (PGCs) exhibit dynamic changes in epigenetic modifications between days 10.5 and 12.5 post coitum (dpc). First, contrary to previous suggestions, we show that PGCs do indeed ac...

Forget the Parents: Epigenetic Reprogramming in Human Germ Cells

Epigenetic reprogramming in the germline resets genomic potential and erases epigenetic memory. Three studies by Gkountela et al., Guo et al., and Tang et al. analyze the transcriptional and epigenetic landscape of human primordial germ cells, revealing a unique transcriptional network and progressive and conserved global erasure of DNA methylation.

Nuclear Reprogramming in Mouse Primordial Germ Cells: Epigenetic Contribution

The unique capability of germ cells to give rise to a new organism, allowing the transmission of primary genetic information from generation to generation, depends on their epigenetic reprogramming ability and underlying genomic totipotency. Recent studies have shown that genome-wide epigenetic modifications, referred to as "epigenetic reprogramming", occur during the development of the gamete ...

Co-culture of Mouse Embryonic Stem Cells with Sertoli Cells Promote in vitro Generation of Germ Cells

  Objective(s): Sertoli cells support in vivo germ cell production; but, its exact mechanism has not been well understood. The present study was designed to analyze the effect of Sertoli cells in differentiation of mouse embryonic stem cells (mESCs) to germ cells.   Materials and Methods: A fusion construct composed of a Stra8 gene promoter and the coding region of enhanced green fluorescence p...
