Effects of NMN supplementation on the ROS levels in heat-stressed porcine oocytes. A Representative images of ROS levels in control, heat-stressed and NMN-supplemented oocytes at metaphase II stage. Scale bar, 30 μm. B The fluorescence intensity of DCFH-DA signals were quantified in control, heat-stressed and NMN-supplemented oocytes. Data were presented as mean value (mean ± SD) of at least three independent experiments. ***P < 0.001
