VASA-positive cells (arrows) in the ovarian surface epithelium and cortex. (A, B) Smaller cells with diameters of 2 to 4 μm in the epithelium. (C-F) Bigger cells with diameters of 10 μm in the epithelium. (G, H) Rare cells with diameters of approximately 30 μm in the cortex. (light microscopy, magnifications 400× and 1000×). Legend: blue-positive cells (Peroxidase/True Blue). Scale bar: 100 μm.
