BACKGROUND The zona pellucida (ZP), an extracellular matrix which surrounds mammalian oocytes, is formed by different glycoproteins. Several studies have revealed that carbohydrate residues present in glycoproteins of ZP play a key role in the sperm-egg recognition. However, the origin and the biochemical composition of ZP remain to be completely resolved. METHODS ZP glycoproteins from rat ovarian follicles were investigated at light and electron microscopic level by the application of… CONTINUE READING
