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 to secret their content during cortical reaction. Here, we characterize cortical granule exocytosis (CGE) in live mouse oocytes activated by strontium chloride using the fluorescent lectin FITC-LCA. We compared the kinetic of CGE between ovulated (in vivo matured, IVO) and in vitro matured (IVM) mouse oocytes. Results show that: 1) IVM oocytes have a severely reduced response to strontium chloride; 2) the low response was confirmed by quantification of remnant cortical granules in permeabilized cells and by a novel method to...
