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

Differentiation of mouse primordial germ cells into female or male germ cells.

Mouse primordial germ cells (PGCs) migrate from the base of the allantois to the genital ridge. They proliferate both during migration and after their arrival, until initiation of the sex-differentiation of fetal gonads. Then, PGCs enter into the prophase of the first meiotic division in the ovary to become oocytes, while those in the testis become mitotically arrested to become prospermatogoni...

Primordial germ cells in mice.

Germ cell development creates totipotency through genetic as well as epigenetic regulation of the genome function. Primordial germ cells (PGCs) are the first germ cell population established during development and are immediate precursors for both the oocytes and spermatogonia. We here summarize recent findings regarding the mechanism of PGC development in mice. We focus on the transcriptional ...

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...

isolation, culture and characterization of chicken primordial germ cells

nowadays, production of recombinant proteins in eukaryotes is gaining good deal of attention. transgenic chicken as a eukaryotic system has a high potential for producing recombinant proteins. post-translational changes, especially glycosylation, are characteristic of the eukaryotic proteins. in practice we need to choose a proper expressing host when considering over-expression of a recombinan...
