Primordial germ cell migration.
Mutational and antisense screens in Drosophila and zebrafish, and transcriptional profiling and time-lapse analysis in the mouse, have contributed greatly to our understanding of PGC development. In all three systems, the behavior of PGCs is controlled by growth factors which signal through G-protein coupled receptors and/or tyrosine kinase receptors. Additionally, regulated cell-cell and cell-...
متن کاملComparative Principles of DNA Methylation Reprogramming during Human and Mouse In Vitro Primordial Germ Cell Specification
Primordial germ cell (PGC) development is characterized by global epigenetic remodeling, which resets genomic potential and establishes an epigenetic ground state. Here we recapitulate PGC specification in vitro from naive embryonic stem cells and characterize the early events of epigenetic reprogramming during the formation of the human and mouse germline. Following rapid de novo DNA methylati...
متن کاملHuman primordial germ cell commitment in vitro associates with a unique PRDM14 expression profile
Primordial germ cells (PGCs) develop only into sperm and oocytes in vivo. The molecular mechanisms underlying human PGC specification are poorly understood due to inaccessibility of cell materials and lack of in vitro models for tracking the earliest stages of germ cell development. Here, we describe a defined and stepwise differentiation system for inducing pre-migratory PGC-like cells (PGCLCs...
متن کاملPrimordial germ cell development in zebrafish.
In sexually reproducing organisms, primordial germ cells (PGCs) give rise to gametes that are responsible for the development of a new organism in the next generation. These cells follow a characteristic developmental path that is manifested in specialized regulation of basic cell functions and behavior making them an attractive system for studying cell fate specification, differentiation and m...
متن کاملPrimordial Germ Cell Specification and Migration
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 gene products known as germ plasm. Once specified, the primordial germ cells of some animals must acquire motility and migrate to the gonad in o...
