Effects of SKAP2 RNAi on spindle migration in mouse oocytes. (A) Spindle localization in mouse oocytes. In the control group, the spindles in most oocytes migrated to the cortex, whereas in the SKAP2 siRNA-injected group, they remained at the center of the cytoplasm. Green: α-tubulin; blue: chromatin. Bar = 20 μm. (B) Percentage of oocytes with spindles at the center in the SKAP2 siRNA-injected group was higher than in the control. *Significantly different (P < 0.05). (C) Cortical granule-free domain formation after SKAP2 siRNA injection in mouse oocytes. In the control group, cortical granules were absent at the cortex near the chromosomes at the MI stage. Cortical granules were distributed consistently across the entire cortex in the SKAP2 siRNA-injected group. Green: cortical granules; blue: chromatin. Bar = 20 μm.
