The oocyte cytoplasm contains several transcripts that are important for early pre-implantation embryo development, and alterations on the amount of these stored mRNA can disturb oocyte competence. The aim of this study was to evaluate the relative a

Autor: João Herbert Moreira Viana, M. M. Pereira, R. V. Serapião, Luiz Sérgio de Almeida Camargo, Marco Antonio Machado, F. Q. Costa
Publikováno v: Reproduction, Fertility and Development. 22:1074
With an aim to improve the in vitro production of bovine embryos, the present study investigated the effect of serum and oxygen tension during IVM on oocyte developmental competence. Four experimental groups were evaluated: G1, 10% oestrus cow serum

Heat stress has been shown to have detrimental effects (41°C) during the first 12 h of in vitro maturation on bovine embryo development (Edwards JL and Hansen PJ 1996 Biol. Reprod. 55, 341-346). However, little is known about the effect on gene expr

In vitro maturation (IVM) is a critical step in in vitro bovine embryo production. A number of factors can influence the IVM environment, such as media composition and protein supplementation. Serum and higher O2 tension have been shown to reduce emb
