Effect of Different Harvesting Techniques on the Recovery and Quality of Bovine Cumulus Oocyte Complexes
This study investigated the effect of different harvesting techniques on the recovery rate and quality of bovine cumulus oocyte complexes (COCs) and their subsequent developmental competence including in vitro maturation, fertilization and blastocyst formation. The COCs were retrieved from slaughter ovaries using aspiration, slicing, or aspiration followed by slicing. The COCs were examined mic...
متن کاملP-110: Effect of Increasing Amount of Oocyte Secreted Factors on Cumulus Expansion of Bovine Cumulus-Oocyte Complexes
Background: In vitro maturation is a good method to decrease cancer risk of superovulation by gonadotropin hormones. A paracrine effect of oocyte secretions on oocyte developmental competence is under investigation. Apart from oocyte maturation, ovulation in vivo requires a precise control of extracellular matrix modification. Cumulus cells secrete hyaluronan to form a muco-elastic extracellula...

متن کامل9-cis Retinoic acid inhibits cumulus cell apoptosis during the maturation of bovine cumulus-oocyte-complexes.
Cumulus cell (CC) apoptosis is inversely correlated with embryonic development in vitro. Therefore, inhibition of CC apoptosis is important for proper embryonic development and quality. Retinoic acids (all-transRA and 9-cisRA) are natural components of retinoids, and 9-cisRA is the physiologically active metabolite of retinoic acid in vitro. During in vitro maturation, 9-cisRA enhances oocyte c...
متن کاملDifferent follicle-stimulating hormone exposure regimens during antral follicle growth alter gene expression in the cumulus-oocyte complex in mice.
Follicle-stimulating hormone (FSH) and oocyte-secreted factors influence granulosa cell differentiation and follicle development. Whereas FSH stimulates the expression of mural cell transcripts, oocyte-secreted factors regulate specific cumulus cell genes and suppress the appearance of mural cell transcripts. This study addresses the extent to which clinically relevant changes in FSH doses appl...
