The aim of the present study was to investigate the beneficial effect of polydatin (PD), the glycoside form of resveratrol, on embryo development in vitro. Oocytes were aspirated from ovaries of Korean Hanwoo cows and cultured until Day 8 in a humidified atmosphere of 5% CO2 in air at 38.5°C. Protein and gene expression levels were determined through(More)
Most mammalian oocytes are arrested at the germinal vesicle stage by activation of Wee1B. Meiotic resumption is regulated by inactivation of Wee1B and activation of cell division cycle 25B. The aim of this study was to determine whether treatment with Wee1B-targeting small interfering RNA (Wee1B-siRNA) promotes nuclear maturation of canine oocytes from(More)
2-Methoxystypandrone (2-MS), a naphthoquinone from Polygonum cuspidatum, has been reported to exhibit antioxidant activities. However, its pharmacological properties have not been fully studied in vitro culture system of oocytes and embryos development. In this study, we examined the effects of 2-MS on bovine blastocyst developmental competency during(More)
Coagulansin-A (withanolide) is the steroidal lactone obtained from Withania coagulans which belong to Solanaceae family. The present study investigated the effects of coagulansin-A on bovine oocyte maturation and embryo development in vitro. All these oocytes were aspirated from the ovaries obtained from Korean Hanwoo cows at a local abattoir. To determine(More)
This study sought to modulate factors that reduce embryo quality in in vitro culture (IVC) systems. Over eight replicates, 3075 oocytes were cultured in in vitro maturation media containing various concentrations of lycopene, followed by in vitro fertilization and culture. The percentages of MII-stage oocytes, the presumptive zygotes that underwent cleavage(More)
