Effect of roscovitine, a cdk1 inhibitor, and of the presence of oocyte on bovine cumulus cell expansion and cyclooxygenase-2 expression.

abstract：:The presence of retinoic acid (RA) during in vitro maturation (IVM) improves bovine oocyte quality and developmental potential. In this work, we investigated the underlying molecular mechanisms. Cumulus-oocyte complexes were meiotically arrested by roscovitine and/or matured in defined medium containing RA, 1% ethanol...
