Abstract

BACKGROUND: The stage of folliculogenesis at which the human zona pellucida (ZP) is initiated and the cells responsible for the origin of the ZP continue to be controversial. This study characterizes the development of the ZP during human folliculogenesis using ovarian samples donated from patients requesting ovarian storage. METHODS: Follicles (from n = 18 patients, 14-40 years old) within fresh tissue and following development in a xenograft system were stained, using immunohistochemical techniques, for the presence of the three human ZP proteins, ZP1, ZP2 and ZP3. Over 500 primordial follicles and >20 follicles at each developmental stage were examined. RESULTS: All three ZP proteins were..
