Clearing the Path for Germ Cells
نویسندگان
چکیده
The chemokine SDF-1a and its receptor CXCR4b guide germ cell migration in zebrafish by activating downstream signaling events. Boldajipour et al. (2008) now report that a second SDF-1a receptor, CXCR7, is also required for guided migration but does not function as a signaling receptor, and instead sequesters SDF-1a. These results highlight the importance of ligand clearance during guided cell migration.

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 کاملتاثیر رتینوئیک اسید در تمایز سلّولهای بنیادی مزانشیمال بافت چربی به سلّولهای زایا
Background: Recent publications regarding the differentiation of stem cells to germ cells have motivated researchers to make new approaches in infertility. In vitro production of germ cells improves the understanding of differentiation process of male and female germ cells. Since using embryonic stem cells for this purpose has been associated with tumorogenesis and ethical criticisms, the men...
متن کاملSertoli 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: ...
متن کاملEffect 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...
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 (...
