Figure 6. (A) Immunofluorescent images of normal and abnormal spindle morphology of control and resveratrol-treated oocytes. Oocytes were stained with α-tubulin antibody (green) and Hoechst (blue) to show spindle morphology and chromosome alignment, respectively. Scale bar: 20 μm. (B) Proportions of the normal and abnormal spindle morphology of aging MII oocytes from control and resveratrol-treated groups. Data are expressed as mean ± SEM of at least 5 independent experiments.
