Mitoquinone improves porcine embryo development through modulating oxidative stress and mitochondrial function.

Oxidative stress caused by excess reactive oxygen species (ROS) is one of the main causes of low efficiency in in vitro production of embryos. These ROS can cause mitochondrial dysfunction and apoptosis, resulting in poor embryo development. Therefore, to prevent mitochondrial damage and apoptosis caused by ROS, we investigated the effects of mitoquinone (MitoQ), a mitochondrial-targeted antioxidant, on the in vitro culture (IVC) of porcine embryos.
