Progress in research on initiation of folliculogenesis has progressed slowly because of a
lack of markers for early folliculogenesis. The rabbit zona pellucida protein (ZP1) is …

The events associated with the early stages of oocyte activation and granulosa cell (GC)
differentiation during ovarian follicular development have been investigated using …

The zona pellucida is the unique extracellular glycoprotein matrix which is assembled
during growth of the mammalian oocyte. The present studies were carried out to examine …

The zona pellucida is a glycoprotein matrix surrounding oocytes and early-stage embryos in
mammals. To elucidate the roles of the zona pellucida glycoproteins ZP1 and ZP3 and their …

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 …

The zona pellucida (ZP) is an extracellular coat that surrounds the mammalian oocyte and
the early embryo until implantation. This coat mediates several critical aspects of fertilization …

Perinatally, oocytes within the mouse ovary become surrounded by a layer of flattened
granulosa cells and form primordial follicles. The subsequent accretion of the zona pellucida …

This study was aimed at investigating zona pellucida glycoproteins (ZP) ZP2, ZP3 mRNA
expression as well as ZP3, ZP4 (ZPB) protein distribution before and after in vitro maturation …

Sections of bovine ovaries fixed in Bouin's fluid or methanol-acetic acid and embedded in
paraffin were incubated with chicken polyclonal antibodies to HPLC-purified zona …

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 …
