説明

The morphological changes were examined in the present study in mouse cumulus-oocyte complexes and granulosa cells induced by the administration of pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG). Dissolution of the germinal vesicle (GVBD) occurred in oocytes at 3 hr after hCG administration. Partial expansion of the cumulus cell investment was observed in the cumulus-oocyte complexes, especially those with the oocytes having undergone GVBD. Cumulus expansion due to the deposition of intercellular materials stained with colloidal iron proceeded up to 8 hr after hCG administration. The number of cells in the follicles containing matured oocytes is smaller than that in the follicles containing intact germinal vesicles in the granulosa cell layer, which indicates that the dispersion of cells occurs during meiotic maturation not only in the cumulus-oocyte complexes but also in the granulosa cell layer. Examination of the expansion of mouse cumulus-oocyte complexes by electron microscopy revealed the abundant deposition of intercellular materials and the retraction of the cytoplasmic processes joining the cumulus cells to the oocyte at 3 hr after hCG administration.
