The Effect of Granulosa Cells Apoptosis on the Cumulus Expansion and the Developmental Competence of Bovine Oocytes

Abstract:

In this study, we used the well in the well (WIW) culture system to study the effect of granulosa cells apoptosis on the cumulus expansion and the developmental competence of bovine oocytes. Results: The apoptosis of granulosa cells affect the cumulus expansion of bovine oocytes significantly. Especially when the percentage of granulosa cells apoptosis exceed 40%, the cumulus expansion was worse. The cumulus expansion affect the oocyte developmental competence of bovine oocytes significantly. The developmental competence of bovine oocyte increases with the increasing of cumulus expansion.
