In the present study, we established an in vitro culture system suitable for generating fertilizable oocytes from premeiotic mouse female germ cells. These results were achieved after first establishing an in vitro culture system allowing immature oocytes from 12-14 day-old mice to reach meiotic maturation through culture onto preantral granulosa cell (PAGC) monolayers in the presence of Activi...
A sequential medium was evaluated on the survival, activation and growth rates of caprine preantral follicles submitted to a long-term culture period, aiming to establish an ideal in vitro culture system. Ovarian fragments were cultured for 16 days in α-MEM(+) alone or supplemented with hormones (GH and/or FSH) added sequentially on different days of culture. Ovarian fragments were cultured in ...
To determine if dibromoacetic acid (DBA) affects ovarian folliculogenesis, four groups of female Dutch-belted rabbits were exposed daily to 0, 1, 5, or 50 mg DBA/kg body weight in drinking water beginning in utero from gestation day 15 throughout life. Functionality of the endocrine axis was assessed by measuring serum concentrations of gonadotropins following an im injection of 10 microg GnRH ...
Abstract Study question Does Mitoquinol have a protective effect on survival and mitochondrial oxidative stress in cultured human preantral follicles? Summary answer significantly increased of follicles for 8 days decreased expression genes related to the response. What is known already Culturing ovarian promising new source mature oocytes fertility preservation, as well key model system invest...
