Small putative stem cells (arrows) expressing SSEA-4 and SOX2-positivity after immunohistochemistry and blue nuclei after DAPI staining of ovarian sections. Small SSEA-4 and SOX2-positive cells were proliferated in ovarian surface epithelium or were found in typical “chambers” with atrophic and autofluorescent (af) tissue nearby. Legend: green-SSEA-4-positivity, red-SOX2-positivity, ose-ovarian surface epithelium, af-autofluorescence, er-erythrocytes (without nuclei). Red bars: 10 μm
