Melatonin Impact on In Vitro Development of Mouse Preantral Follicles and Oocyte Maturation
Introduction: Melatonin acts as an indirect antioxidant and is a powerful direct free radical scavenger and direct responses to melatonin in the gonads are detected. This study aims to investigate the influence of different doses of melatonin on preantral follicle development and oogenesis of in vitro cultured mouse ovarian follicles. Materials and Methods: Preantral follicles with diamet...
متن کاملP-128: Fibroblast Growth Factor Improves Oocyte Maturation in Vitrified-Thawed Mouse Follicles
Background: The fibroblast growth factors (FGF-4) are a group of heparin-binding single chain polypeptides that play a pivotal role in development, cell growth, tissue repairing and transformation. The aim of this study is to improve development and maturation outcome of vitrified mouse pre-antral follicle by adding of fibroblast growth factor (FGF) into medium culture. Materials and Methods: P...
متن کاملIn Vivo oocyte maturation and ovulation in females and spermiation in males of hybrid sturgeon, bester
Bester, a hybrid sturgeon (Huso huso L. females ´ Acipenser ruthenus L. males), neither spermiate nor ovulate in the captivity. Thirteen-year-old adult male and female bester were injected with LH-RHa (0.1-0.3 mg/kg B.W.) intramuscularly and spawning status of the treated fish was checked 24-48 hours later. Additionally, changes in serum levels of DHP in both the responded and the non-responded...

متن کاملTranscription reactivation steps stimulated by oocyte maturation in C. elegans.
Developing oocytes produce materials that will support early embryonic development then cease transcription before fertilization. Later, a distinct transcription program is established in the embryo. Little is understood about how these global gene regulation transitions are effected. We have investigated in C. elegans how oocyte transcription is influenced by maturation, a process that release...
