Mitochondrial Patterns in Bovine Oocytes with Different Meiotic Competence Related to Their in vitro Maturation

Popis výsledku v původním jazyce

Contents This study was designed to specify chromatin and mitochondrial patterns in bovine oocytes with different meiotic competence in relation to maturation progress, resumption of meiosis, MII onset and completion of maturation. Oocytes with greater or lesser meiotic competence, recovered separately from medium (MF) and small follicles (SF), were categorized according to morphology. Four oocyte categories, healthy and light-atretic MF and healthy and light-atretic SF oocytes were matured and collected at 0, 3, 7, 16 and 24h of maturation. Specific differences in terms of chromatin and mitochondrial patterns were found among the maturing oocyte categories. Resumption of meiosis was accelerated in light-atretic oocytes, as compared with healthy oocytes, regardless of their meiotic competence. More competent oocytes activated mitochondria twice during maturation, before resumption of meiosis and before completion of maturation, while less competent oocytes did it only once, before comp
