Mogroside V protects porcine oocytes from in vitro ageing by reducing oxidative stress through SIRT1 upregulation

Figure 4. Effects of mogroside V on mitochondrial and ATP contents in oocytes during in vitro ageing. After in vitro maturation for 44 h, oocytes that extruded the first polar body were continuously cultured in vitro with or without MV for 24 h. (A) Representative images of fresh, aged and aged+MV oocytes stained with MitoTracker™ Orange CMTMRos. (B) Quantitative analysis of the mitochondrial content. (C) Quantitative analysis of the ATP content. The data are presented as the mean ± SEM of at least three independent experiments. MV, mogroside V; Scale bar = 50 μm. * P < 0.05, *** P < 0.001, **** P < 0.0001.
