چکیده انگلیسی
Bovine embryo production is practiced worldwide for commercial purposes. A major concern of embryo suppliers is the impact of in vitro production systems on embryo quality. In the present study, we compared Buffalo Rat Liver cell coculture with semidefined, medium-based culture, oocytes recovered postmortem with those obtained from live animals, and in vitro with in vivo embryo development. Gene expression levels in expanded blastocysts were measured using microarray and quantitative RT-PCR. The systems were similar in terms of blastocyst yield and rate of development, whereas embryo productivity was greater for immature oocytes collected in vivo. Although immature oocytes collected in vivo had greater developmental competence, they yielded blastocysts that were indistinguishable (in terms of level of gene expression) from embryos derived from immature oocytes recovered postmortem. Culture conditions had a significant impact on gene expression, particularly among genes involved in lipid metabolism. Numerous uncharacterized novel transcript regions were also influenced by in vitro treatments. In conclusion, ovum pick-up combined with in vitro culture in semidefined medium provided a high blastocyst yield, without the deleterious effects associated with coculture.
