This study examines the effects of adding insulin-transferrin-selenium (ITS) and/or L-ascorbic acid (ASC) to a conventional medium for maturing prepubertal calf oocytes on chromosome organization, cortical granule (CG) distribution, and embryo development to the blastocyst stage. Cumulus-oocyte complexes (COCs) were matured in medium TCM 199 containing PVA(More)
During the in vitro maturation of adult bovine oocytes, leptin has beneficial effects on blastocyst development, apoptosis and transcription levels of developmentally important genes. The present study analyzes the differential effects of leptin on prepubertal bovine oocytes and cumulus cells. Effects were determined of leptin treatment during oocyte(More)
