The human oocyte is surrounded by the zona pellucida—an elastic, transparent extracellular
matrix consisting of specific glycoproteins. The zona pellucida is preserved after fertilization …

Despite decades of research, the mechanism by which the fertilizing spermatozoon
penetrates the mammalian vitelline membrane, the zona pellucida (ZP) remains one of the …

Of all the stages of mammalian folliculogenesis, the primordial to primary follicle transition is
the least understood. In order to gain new insights into this process, we have conducted a …

The zona pellucida (ZP) participates in sperm–egg interactions during the first steps of
fertilization. Recent studies have shown that the ZP matrix of oocytes in several species is …

The ovary does not have a distinct morphologic barrier between the immune system and the
developing gametes. This is in contrast to the testis in which the junctional complexes …

The avian perivitelline membrane (PVM) is the site of initial contact between sperm and egg.
It consists of only two major components, which are both homologues of the mammalian …

Ооцит человека окружен блестящей оболочкой–zona pellucida–эластичным,
прозрачным внеклеточным матриксом, состоящим из специфических гликопротеинов …

In the dog, attempts to localize the expression of zona pellucida (ZP) proteins during
folliculogenesis have failed to demonstrate conclusively whether any or all of the zona …

Mammalian mothers undergoing embryo implantation must specifically recognize the
developing embryo in a species-restricted manner. We previously observed that immune …

Domestic ewes (Ovis aries) were immunised with porcine zonae pellucidae (pZP) or pZP
conjugated to keyhole limpet haemocyanin (KLH) in adjuvant (s) to examine the feasibility of …
