Fig. 4From: Nicotinamide mononucleotide supplementation improves the quality of porcine oocytes under heat stressEffects of NMN supplementation on the actin polymerization in heat-stressed porcine oocytes. A Representative images of actin filaments in control, heat-stressed and NMN-supplemented oocytes at metaphase I stage. Scale bar, 30 μm. B The fluorescence intensity of actin 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
