Carboxyethylgermanium sesquioxide (Ge-132) treatment during in vitro culture protects fertilized porcine embryos against oxidative stress induced apoptosis.

ABSTRACT: Compared with the in vivo environment, porcine in vitro embryo-culture systems are suboptimal, as they induce oxidative stress via the accumulation of reactive oxygen species (ROS). High ROS levels during early embryonic development cause negative effects, such as apoptosis. In this study, we examined the effects of the antioxidant carboxyethylgermanium sesquioxide (Ge-132) during in vitro culture (IVC) on embryonic development in porcine in vitro fertilization (IVF) embryos. Zygotes were treated with different concentrations of Ge-132 (0, 100, 200 and 400 μg/ml). All of the Ge-132 treatment groups displayed greater total cell numbers after IVC (98.1, 98.5 and 103.4, respectively) compared with the control group (73.9). The 200 μg/ml Ge-132 treatment group exhibited significantly increased
