ZONA PELLUCIDA GLYCOPROTEINS [PDF]
Annual Review of Biochemistry, 1988 All mammalian eggs are surrounded by a relatively thick extracellular coat, the zona pellucida, that plays vital roles during oogenesis, fertilization, and preimplantation development. The mouse zona pellucida consists of three glycoproteins that are synthesized solely by growing oocytes and assemble into long fibrils that constitute a matrix.

Reproductive Biology and Endocrinology, 2008 Background In human and rodents, sperm-zona pellucida binding is mediated by a sperm surface Galactosyltransferase that recognizes N-Acetylglucosamine residues on a glycoprotein ZPC. In large domestic mammals, the role of these molecules remains unclear:

Acta Veterinaria Scandinavica, 2007 Background Zona pellucida binding assays (ZBAs) have proven useful in determining the fertilising ability of spermatozoa in several species. Most ZBAs use fresh or salt-stored oocytes collected from fresh ovaries but because ovaries are not easy to ...

Space asymmetry directs preferential sperm entry in the absence of polarity in the mouse oocyte. [PDF]
PLoS Biology, 2006 Knowledge about the mechanism that establishes embryonic polarity is fundamental in understanding mammalian development. In re-addressing several controversial claims, we recently proposed a model in which mouse embryonic polarity is not specified until ...

Morphocytometric Evaluation of Equine Oocytes Following In Vitro Maturation
Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Veterinary Medicine, 2023 In the current study, 930 equine oocytes were collected, 765 (82.25%) of which were considered viable for in vitro maturation. All selected oocytes were matured for 27 h at 38.50 0C in an atmosphere of 5% CO2 in humidified air.

The effects of electroporation on viability and quality of in vivo-derived bovine blastocysts
The Journal of Reproduction and Development, 2019 The introduction of exogenous molecules into embryos is required for analyses of molecular dynamics and specific gene functions during early embryonic development. Electroporation is an effective method to transport exogenous molecules into cells, but is
