Representative H&E images of OSE cells smears. A-G. Large numbers of cells were observed singly and as small clusters with cytoplasmic continuity. These clusters appear to be the putative germ cell nests. Stem cells and germ cell nests were darkly stained with H&E. OSE cells smears were prepared from 24 months old mice ovaries. F and G are the higher magnification images of GCN encircled in red and blue respectively in C. The experiments were repeated three times. Scale: 20 µm
