Fusion of cortical granules with the oocyte plasma membrane is the most significant event to prevent polyspermy. This particular exocytosis, also known as cortical reaction, is regulated by calcium and its molecular mechanism ...

Oocyte in vitro maturation does not entirely support all the nuclear and cytoplasmic changes that occur physiologically and it is poorly understood whether in vitro maturation affects the competence of cortical granules ...

Compensatory endocytosis (CE) is one of the primary mechanisms through whichcells maintain their surface area after exocytosis. Considering that in eggs massiveexocytosis of cortical granules (CG) takes place after ...

Cortical granule exocytosis (CGE), also known as cortical reaction, is a calciumregulated secretion that represents a membrane fusion process during meiotic cell division of eggs. The molecular mechanism of membrane fusion ...

The aim of this study was to evaluate the effects of hCG, progesterone and oestradiol supplementation on nuclear and cytoplasmic maturation of canine oocytes cultured for 24, 48, 72 and 96 h. Oocytes obtained from 18 healthy ...
