Figure 2.
Intracellular ROS levels were measured by assessing DCFH fluorescence (A–F). Quantitative analysis showed that the ROS levels of four- and eight-cell embryos were significantly decreased (P < 0.05) in the FOVE group compared with the control group (C–F). There were no significant difference in ATP content between two- and four-cell shown in (G–J) (P > 0.05). As shown in Figures 2K, L, the ATP levels of eight-cell embryos were significantly higher in the FOVE group than in the control group (P < 0.05).
