The relationship between antral follicle count in a bovine ovary and developmental competence of in vitro-grown oocytes derived from early antral follicles.
To clarify the relationship between ovarian reserve and the developmental competence of bovine oocytes, oocyte-granulosa complexes (OGCs) collected from early antral follicles (≤ 1 mm) in ovaries with high (≥ 25) and low (<25) antral follicle counts (AFCs) were used. OGCs derived from different AFC groups were cultured for growth followed by maturation, fertilization and blastocyst formation. V...
متن کاملImprovement of the developmental competence of porcine oocytes collected from early antral follicles by cytoplast fusion
In the present study, we propose an alternative technique called cytoplast fusion to improve the maturation rate and developmental competence of growing oocytes collected from early antral follicles in pigs. We examined whether the fusion of a growing oocyte with the cytoplast from a fully-grown oocyte (CFR group) could better promote maturation and developmental competence of the growing oocyt...
متن کاملDevelopmental competence of immature oocytes aspirated from antral follicles in patients with gynecological diseases
BACKGROUND In vitro maturation (IVM) of immature oocytes collected from ovary has been proposed for fertility preservation. In addition, quality of oocytes post IVM is one of the factors determining its developmental competence. By using the non-invasive Polscope system, both meiotic spindle (MS) and zona pellucida (ZP) can be assessed in living oocytes. OBJECTIVE The aim was to investigate t...
متن کاملEffects of reaggregated granulosa cells and oocytes derived from early antral follicles on the properties of oocytes grown in vitro
In this study, we examined the effects of reconstructed oocyte-granulosa cell complexes (OGCs) on the development of porcine oocytes derived from early antral follicles (EAFs; 0.5-0.7 mm in diameter). When denuded oocytes were cocultured with granulosa cells derived from other EAFs, the oocytes and granulosa cells aggregated to form OGCs after 2 days of culture. After 14 days of culture, we com...
متن کاملResveratrol-induced mitochondrial synthesis and autophagy in oocytes derived from early antral follicles of aged cows
Mitochondrial numbers increase during oocyte growth. In this study, we collected oocytes and granulosa cell complexes (OGCs) from early antral follicles (EAFs) of aged cows (> 120 months of age) and examined the effects of resveratrol on mitochondrial generation, degradation, and quality in oocytes grown in vitro. We also examined the effects of resveratrol on gene expression of the granulosa c...
