Response of Mouse Zygotes Treated with Mild Hydrogen Peroxide as a Model to Reveal Novel Mechanisms of Oxidative Stress-Induced Injury in Early Embryos

Figure 1

Comparisons of embryo development between zygotes from groups with different concentration of H₂O₂ and control group. (a) Representative images of embryos at 96 hpi from control group and 0.03 mM H₂O₂ group. (b) Counting out the cleavage rates from each group, blastocyst formation rate declined from 0.03 mM H₂O₂ group; early embryos showed stagnation from 0.04 mM H₂O₂ group. Data are presented as mean ± SD in six independent experiments for each group at least. Differences between the groups were calculated using Chi square test. ; ; compared with the control group.
