from stem cells to germ cells and from germ cells to stem cells

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...

Sertoli cell condition medium can induce germ like cells from bone marrow derived mesenchymal stem cells

Objective(s): Although many researchers have confirmed induction of germ cells from bone marrow mesenchymal stem cells (BMMSCs), there are no reports that confirm spontaneous differentiation of germ cells from BMMSCs. In this study, we have evaluated the effect of adult Sertoli cell condition medium (SCCM) as a mutative factor in the induction of germ cells from BMMSCs. Materials and Methods: ...

Functional Concentrations of BMP4 on Differentiation of Mouse Embryonic Stem Cells to Primordial Germ Cells

A vector-based system for the differentiation of mouse embryonic stem cells toward germ-line cells

Objective(s):To culture thein vitro mouse embryonic stem cells (mESCs) and to direct their  differentiation to germ-line cells; in present study we used a vector backbone containing the fusion construct Stra8-EGFP to select differentiated ES cells that entered meiosis.  Retinoic acid was used to differentiate embryonic stem cells to germ cells. Materials and Methods: A fragment of Stra8 gene pr...

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...

Germ cells from mouse and human embryonic stem cells.

Mammalian gametes are derived from a founder population of primordial germ cells (PGCs) that are determined early in embryogenesis and set aside for unique development. Understanding the mechanisms of PGC determination and differentiation is important for elucidating causes of infertility and how endocrine disrupting chemicals may potentially increase susceptibility to congenital reproductive a...
