New applications for bovine IVP technology: from ‘single oocyte culture’ to toxicity screening
Bovine in vitro embryo production (IVP) has been around for about three decades. Over the years, it has gained a reputation as one of the most applicable of the high-tech bovine assisted reproduction techniques. It is well known that its ups and downs are basically driven by economic imperatives depending on the agricultural system in which it is used. In parallel, there has always been a stron...
متن کاملEffect 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 کاملSingle oocyte bisulfite mutagenesis.
Epigenetics encompasses all heritable and reversible modifications to chromatin that alter gene accessibility, and thus are the primary mechanisms for regulating gene transcription. DNA methylation is an epigenetic modification that acts predominantly as a repressive mark. Through the covalent addition of a methyl group onto cytosines in CpG dinucleotides, it can recruit additional repressive p...
متن کاملO-10: Assessment of Oocyte and Embryo Quality in Different Time between Oocyte Retrieval and hCG Priming
Background: Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hCG) administration. Materials and Methods: A total of 985 metaphase II were ...
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...
