Germ cells from mouse and human embryonic stem 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...

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

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 (...

Effect of Different Concentrations of Forskolin Along with Mature Granulosa Cell Co-Culturing on Mouse Embryonic Stem Cell Differentiation into Germ-Like Cells

Background: Germ cell development processes are influenced by soluble factors and intercellular signaling events between them and the neighboring somatic cells. More insight into the molecular biology of the germ cell development from embryonic stem (ES) cells and investigation of appropriate factors, specifically those targeting differentiation process, is of great importance. In this study, w...

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...

Effects of Treatment with Bone Morphogenetic Protein 4 and Co-culture on Expression of Piwil2 Gene in Mouse Differentiated Embryonic Stem Cells

Background Specific growth factors and feeder layers seem to have important roles in in vitro embryonic stem cells (ESCs) differentiation. In this study,the effects of bone morphogenetic protein 4 (BMP4) and mouse embryonic fibroblasts (MEFs) co-culture system on germ cell differentiation from mouse ESCs were studied. MaterialsAndMethods Cell suspension was prepared from one-day-old embryoid bo...
