An investigation of primordial germ cell development in embryo and larvae of Huso huso
In sturgeons, Primordial Germ Cells originate from the vegetal pole of the egg. They migrate toward genital ridges during developmental stages and finally differentiate into gametes (the only cells that transmit genetic information). In this study, the cells were isolated from the place of migration of primordial germ cells in Huso huso’s larvae during two stages before and after absorption of ...
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 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 کاملRegulation of primordial germ cell development in the mouse.
Primordial germ cells (PGCs) are the founders of the gametes. They arise at the earliest stages of embryonic development and migrate to the gonadal ridges, where they differentiate into oogonia/oocytes in the ovary, and prospermatogonia in the testis. The present article is a review of the main studies undertaken by the author with the aim of clarifying the mechanisms underlying the development...
متن کاملSmad5 is required for mouse primordial germ cell development
Smad5, together with Smad1 and Smad8, have been implicated as downstream signal mediators for several bone morphogenetic proteins (BMPs). Recent studies have shown that primordial germ cells (PGCs) are absent or greatly reduced in Bmp4 or Bmp8b mutant mice. To define the role of Smad5 in PGC development, we examined PGC number in Smad5 mutant mice by Oct4 whole-mount in situ hybridization and a...
