Fig. 2

A Representative images of spindle/chromosome organization in oocytes from aged mice with or without 10 μM quercetin treatment. Spindles were stained with α‐tubulin antibody (green), and chromosomes were counterstained with DAPI (blue). Scale bar, 10 μm. B Distinct cortical granules (CGs) distributions with or without quercetin treatment. CGs in oocytes were stained with lens culinaris (LCA)‐FITC (fluorescein isothiocyanate: green), and chromosomes were stained with DAPI (blue). Scale bar, 25 μm. C Quantification of abnormal spindle/chromosomes oocytes with or without quercetin treatment. D The proportion of oocytes with abnormally distributed CGs, following quercetin treatment. Data are means ± SD of at least three independent experiments. *P < 0.05 vs. control as calculated by two-tailed unpaired Student’s t-tests.
