Melatonin prevents postovulatory oocyte aging and promotes subsequent embryonic development in the pig
Oxidative stress is known as a major contributing factor involved in oocyte aging, which negatively affects oocyte quality and development after fertilization. Melatonin is an effective free radical scavenger and its metabolites AFMK and AMK are powerful detoxifiers that eliminate free radicals. In this study, we used porcine oocytes to test the hypothesis that melatonin could scavenge free rad...
متن کاملSupplementing fibroblast growth factor 2 during bovine oocyte in vitro maturation promotes subsequent embryonic development
The overall objective of this work was to describe whether supplementing fibroblast growth factor 2 (FGF2) during in vitro maturation (IVM) affects cumulus and oocyte maturation and subsequent embryonic development. Supplementing 0.5, 5 or 50 ng/ml FGF2 to cumulus-oocyte complexes (COCs) increased the percentage of oocytes with extruded polar bodies after IVM. Supplementing FGF2 during COC matu...
متن کاملSevere cytoplasmic abnormalities of the oocyte decrease cryosurvival and subsequent embryonic development of cryopreserved embryos.
BACKGROUND Abnormalities of oocyte morphology affect embryo quality and viability. Whether morphological abnormalities of the oocyte influence cryosurvival and further development of derived embryos is not known. The aim of this study was to compare cryosurvival and progression to the blastocyst stage of frozen-thawed embryos derived from normal and abnormal oocytes. METHODS A total of 5292 G...
متن کاملEffect of protein supplement source on porcine oocyte maturation and subsequent embryonic development after parthenogenetic activation.
The aim of this study was to compare the effect of purified GPBoS and commonly used FCS on porcine oocyte maturation and subsequent embryonic development after their parthenogenetic activation. COCs were obtained from dissected follicles and cultured for 18, 24, 30, 36, 42 and 48 h in M-199 medium either with GPBoS or FCS. After 24 h with GPBoS, 91% of oocytes reached MI stage while in the medi...
متن کاملP-131: Effects of Heat Shock during Early Stage of Oocyte Maturation on Meiotic Progression and Subsequent Embryonic Development and Gene Expressionin Ovine
Background: Heat shock may affect different aspects of oocyte maturation and its subsequent development to the blastocyst stage. A series of in vitro experiments was performed to determine whether physiologically heat shock (41°C) disrupts the progression of the ovine oocytes through meiosis, activation and blastocyst formation. Materials and Methods: The cumulus-oocyte complexes (COCs) were as...
