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 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 (...
متن کاملProgrammed cell death of primordial germ cells in Drosophila is regulated by p53 and the Outsiders monocarboxylate transporter.
Primordial germ cell development uses programmed cell death to remove abnormal, misplaced or excess cells. Precise control of this process is essential to maintain the continuity and integrity of the germline, and to prevent germ cells from colonizing locations other than the gonads. Through careful analyses of primordial germ cell distribution in developing Drosophila melanogaster embryos, we ...
متن کاملThe active migration of Drosophila primordial germ cells.
We describe our analysis of primordial germ cell migration in Drosophila wild-type and mutant embryos using high resolution microscopy and primary culture in vitro. During migratory events the germ cells form transient interactions with each other and surrounding somatic cells. Both in vivo and in vitro they extend pseudopodia and the accompanying changes in the cytoskeleton suggest that actin ...
متن کاملAn 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 ...
