Zona pellucida removal by acid Tyrode's solution affects pre- and post-implantation development and gene expression in mouse embryos(dagger) [PDF]

, 2022
Zona pellucida removal by acid Tyrode's solution affects the inner cell mass/trophectoderm differentiation; a lower fetal rate, higher placental weight, and a total of 473 differentially expressed genes during post-implantation development in mice.

Application of a zona pellucida binding assay (ZBA) in the domestic cat benefits from the use of in vitro matured oocytes

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 ...

Laser microdissection as a new approach to prefertilization genetic diagnosis [PDF]

, 2000
The genetic status of oocytes can be determined by polar body (PB) analysis. Following PB extraction, a genetic evaluation is performed. As each PB contains the complementary genetic material of the oocyte, PB analysis reveals information about its ...

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 ...

Zona pellucida-induced acrosome reaction in human spermatozoa is potentiated by glycodelin-A via down-regulation of extracellular signal-regulated kinases and up-regulation of zona pellucida-induced calcium influx [PDF]

, 2010
Background Glycodelin-A interacts with spermatozoa before fertilization, but its role in modulating sperm functions is not known. Zona pellucida-induced acrosome reaction is crucial to fertilization and its dysfunction is a cause of male infertility.

Das Zusammenspiel der Proteasen Akrosin und Ovastacin bei der Härtung der Zona pellucida [PDF]

, 2021
Die Zona pellucida umgibt die Eizellen von Säugetieren und ist in der Maus aus den Zona pellucida Proteinen 1-3 aufgebaut. Diese Proteine vermitteln vor der Befruchtung den ersten Kontakt von Spermium und Eizelle. Nach der Befruchtung verhindert die Zona

The effect of chemical treatment of the sheep embryo zona pellucida on the ability of blastocysts to hatch after vitrification and warming

Veterinary Medicine and Science, 2022
Background The embryo release from the zona pellucida is of prerequisites of successful implantation. Objectives Regarding the negative impact of embryo cryopreservation on the blastocysts hatchability, the aim of the present study was to investigate the

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.

Cracking the egg: increased complexity in the zona pellucida [PDF]

, 2005
A functional zona pellucida is critical for both fertilization and the early stages of embryo development. Recent data from genomic and proteomic studies have questioned our simplistic view of the zona as being composed of three proteins whose functions ...
