Detection of zona pellucida proteins during human folliculogenesis.
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 fre...
متن کاملHuman sperm degradation of zona pellucida proteins contributes to fertilization
BACKGROUND The mammalian oocyte extracellular matrix known as the zona pellucida (ZP) acts as a barrier to accomplish sperm fusion with the female gamete. Although penetration of the ZP is a limiting event to achieve fertilization, this is one of the least comprehended stages of gamete interaction. Even though previous studies suggest that proteases of sperm origin contribute to facilitate the ...
متن کاملInfluence of the zona pellucida of the mouse egg on folliculogenesis and fertility.
All mammalian eggs are surrounded by a relatively thick extracellular coat, called the zona pellucida (ZP), that plays vital roles during oogenesis, fertilization, and preimplantation development. The mouse egg ZP consists of three glycoproteins, called mZP1-3, that are synthesized solely by oocytes during their 2-to-3 week growth phase. The ZP is seen initially as isolated extracellular deposi...

متن کاملA duplicated motif controls assembly of zona pellucida domain proteins.
Many secreted eukaryotic glycoproteins that play fundamental roles in development, hearing, immunity, and cancer polymerize into filaments and extracellular matrices through zona pellucida (ZP) domains. ZP domain proteins are synthesized as precursors containing C-terminal propeptides that are cleaved at conserved sites. However, the consequences of this processing and the mechanism by which na...
