In vitro embryo production from cumulus–oocyte complexes type II in Bos indicus cattle

The objective of this work was to evaluate the effect of COC morphology from Bos indicus animals with signs of early atresia versus no signs of atresia on in vitro embryo production.

Description
Summary:The objective of this work was to evaluate the effect of COC morphology from Bos indicus animals with signs of early atresia versus no signs of atresia on in vitro embryo production. Lonergan P, Rizos D, Gutierrez-Adan A, Fair T, Boland MP. Oocyte and embryo quality: effect of origin, culture conditions and gene expression patterns. Satellite DNA methylation status and expression of selected genes in Bos indicus blastocysts produced in vivo and in vitro. Recombinant bovine interferon-T enhances in vitro development of bovine embryos by upregulating expression of connexin 43 and E-cadherin.
