Fig. 10From: Nicotinamide mononucleotide supplementation improves the quality of porcine oocytes under heat stressEffects of NMN supplementation on the early apoptosis of heat-stressed porcine oocytes. A Representative images of apoptotic oocytes at metaphase II stage in control, heat-stressed and NMN-supplemented groups. Scale bar, 30 μm. B The fluorescence intensity of Annexin-V signals was quantified in control, heat-stressed and NMN-supplemented oocytes. Data were presented as mean value (mean ± SD) of at least three independent experiments. ***P < 0.001Back to article page
