Association of MPF, MAPK, and nuclear progression dynamics during activation of young and aged bovine oocytes.

abstract：:For mammalian organism, fertilization begins with species-specific recognition between sperm and egg, a process depending upon egg zona pellucida glycoproteins and putative sperm interacting protein(s). In mouse, zona pellucida glycoprotein ZP3 is believed to be the primary receptor for sperm and inducer of sperm acro...
