Primordial Germ Cell Specification and Migration [version 1; referees: 3 approved] [PDF]
Primordial germ cells are the progenitor cells that give rise to the gametes. In some animals, the germline is induced by zygotic transcription factors, whereas in others, primordial germ cell specification occurs via inheritance of maternally provided ...

Primordial Germ Cells in Mice [PDF]
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.

Mammalian primordial germ cell specification [PDF]
ABSTRACT The peri-implantation window of mammalian development is the crucial window for primordial germ cell (PGC) specification. Whereas pre-implantation dynamics are relatively conserved between species, the implantation window marks a stage of developmental divergence between key model organisms, and thus potential variance in the ...

PAR6, a potential marker for the germ cells selected to form primordial follicles in mouse ovary. [PDF]
Partitioning-defective proteins (PAR) are detected to express mainly in the cytoplast, and play an important role in cell polarity. However, we showed here that PAR6, one kind of PAR protein, was localized in the nuclei of mouse oocytes that formed ...

Functional analysis of the Drosophila embryonic germ cell transcriptome by RNA interference. [PDF]
In Drosophila melanogaster, primordial germ cells are specified at the posterior pole of the very early embryo. This process is regulated by the posterior localized germ plasm that contains a large number of RNAs of maternal origin.

Analysis of chicken primordial germ cells [PDF]
Primordial germ cells (PGCs) are precursors of germline cells. Although avian PGCs have been used to produce transgenic birds, their characteristics largely remain unknown. In this study, we isolated PGCs from chicken embryos at various developmental stages and analyzed the gene expression.

Collectively stabilizing and orienting posterior migratory forces disperses cell clusters in vivo
During development, primordial germ cell clusters undergo dispersal but how cell–cell adhesion and contractility are coordinated during this process in vivo is unclear. Here, the authors show that Drosophila primordial germ cells utilize migratory forces

Primordial germ cells undergo three significant processes on their path to becoming primary oocytes: the initiation of meiosis, the formation and breakdown of germ cell nests, and the assembly of single oocytes into primordial follicles.

Follistatin288 Regulates Germ Cell Cyst Breakdown and Primordial Follicle Assembly in the Mouse Ovary. [PDF]
In mammals, the primordial follicle pool represents the entire reproductive potential of a female. The transforming growth factor-β (TGF-β) family member activin (ACT) contributes to folliculogenesis, although the exact mechanism is not known.
