Heat shock during in vitro maturation induces chromatin modifications in the bovine embryo

19 Aug 2019

Abstract excerpt

Heat stress compromises bovine oocyte developmental competence, but the effects of high temperature during oocyte maturation on embryo chromatin organization is unknown. In this study bovine oocytes were exposed to heat shock (41°C) for 12 h during in vitro maturation and then submitted to in vitro fertilization. The heat shock did not affect (P > 0.05) the cleavage but reduced (P < 0.01) the blastocyst rate on...
