Addition of CP promoted early porcine embryo development in present of H₂O₂. Images (A), cleavage (B), and blastocyst formation (C) of embryos in control, H₂O₂, H₂O₂ + CP, and CP groups. (D) Blastocysts were graded on a scale from 1 to 6 as illustrated. Different scores are indicated by the respective numbers. (E) Blastocyst quality was examined in the control, H₂O₂, H₂O₂ + CP, and CP groups. Data are expressed as the mean ± SEM. In addition, *p < 0.05, **p < 0.01, and ***p < 0.001 indicate significant differences between different groups. Bar = 200 µm. The experiments were replicated six times with 1226 embryos.
