Depletion of Ovarian Primordial Follicles after Gamma Irradiation
Introduction:Artifical sourace of radiation have increased worldwide average annual exposure of mankind and could especially affect rapidly dividing cells in gonads. Since, radiation sensitivities of different components of primordial follicles, and the time required for their deplation have not been morphologically eatablished we decided to estimate the time required for depletion of primordi...

متن کاملThe nuage mediates retrotransposon silencing in mouse primordial ovarian follicles.
Mobilization of endogenous retrotransposons can destabilize the genome, an imminent danger during epigenetic reprogramming of cells in the germline. The P-element-induced wimpy testis (PIWI)-interacting RNA (piRNA) pathway is known to silence retrotransposons in the mouse testes. Several piRNA pathway components localize to the unique, germline structure known as the nuage. In this study, we su...
متن کاملFrom primordial germ cells to primordial follicles: a review and visual representation of early ovarian development in mice
BACKGROUND Normal development of reproductive organs is crucial for successful reproduction. In mice the early ovarian developmental process occurs during the embryonic and postnatal period and is regulated through a series of molecular signaling events. Early ovarian development in mice is a seventeen-day process that begins with the rise of six primordial germ cells on embryonic day five (E5)...
متن کاملAnti-Müllerian hormone inhibits initiation of growth of human primordial ovarian follicles in vitro.
BACKGROUND Anti-Müllerian hormone (AMH) inhibits the initiation of the development and early growth of mouse ovarian follicles. Furthermore, the ovarian follicle pool diminishes prematurely in AMH-knockout mice. In this study, we examined whether AMH plays a similar role in humans, controlling ovarian follicle growth. METHODS Human ovarian cortical tissue biopsy specimens were cut into small ...
