Effects of oocyte collection techniques and maturation media on in vitro maturation and subsequent embryo development in Boer goat [PDF]

Czech Journal of Animal Science, 2007
The oocytes (experiment 1) were harvested by one of the four collection techniques (slicing, puncture, aspiration I and aspiration II) and the total number and the number of each grade of oocytes were counted, respectively. The good-quality oocytes (good

Enhancing oocyte in vitro maturation and quality by melatonin/bilirubin cationic nanoparticles: A promising strategy for assisted reproduction techniques

International Journal of Pharmaceutics: X
In assisted reproduction techniques, oocytes encounter elevated levels of reactive oxygen species (ROS) during in vitro maturation (IVM). Oxidative stress adversely affects oocyte quality, hampering their maturation, growth, and subsequent development ...

The effect of vitrification after warming on the expressions of p38, CDK1, and cyclin B in immature goat oocytes followed by in vitro maturation [PDF]

Veterinary World, 2020
Background and Aim: The combination of vitrification techniques and in vitro maturation can reduce oocyte competence. Mitogen-activated protein kinase and maturation-promoting factor are significant in oocyte meiotic maturation regulation.

Effect of adding growth factors during in vitro maturation on the developmental potentials of ewe oocytes selected by brilliant cresyl blue staining [PDF]

Veterinary World, 2021
Aim: Several factors had been concerned with the developmental competence of the sheep oocyte. This study aims to investigate the effect of adding growth factors (insulin-like growth factor 1 [IGF-1] and epidermal growth factor [EGF]) in the maturation ...

Comparative Proteomic Analysis of Buffalo Oocytes Matured in vitro Using iTRAQ Technique [PDF]

Scientific Reports, 2016
AbstractTo investigate the protein profiling of buffalo oocytes at the germinal vesicle (GV) stage and metaphase II (MII) stage, an iTRAQ-based strategy was applied. A total of 3,763 proteins were identified, which representing the largest buffalo oocytes proteome dataset to date.

Bovine in vitro oocyte maturation and embryo culture in liquid marbles 3D culture system.

PLoS ONE, 2023
Despite the advances in in vitro embryo production (IVP) over the years, the technique still has limitations that need to be overcome. In cell cultures, it is already well established that three-dimensional culture techniques are more physiological and ...
