Fig 6. Effect of resveratrol on the cell-free mitochondrial DNA copy number in the spent culture medium of blastocysts.

The spent culture medium of the blastocysts derived from fresh or vitrified-warmed embryos cultured with or without resveratrol (0.5 μM) for 5 days was examined. Bars with different letters represent differences between treatments (P < 0.05). Data are presented as mean ± SEM.
