Figure 9From: Small SSEA-4-positive cells from human ovarian cell cultures: related to embryonic stem cells and germinal lineage? Small putative stem cells (arrows) in ovarian and testicular cell cultures were positively stained on alkaline phosphatase (AP). A proportion of small putative stem cells were SOX-2 positive. Scale bars: 100 μm (A, D); 50 μm (B, E); 10 μm (C, F).Back to article page
