Figure 7From: β-catenin/Tcf-signaling appears to establish the murine ovarian surface epithelium (OSE) and remains active in selected postnatal OSE cellsApoptosis is not detected in neonatal OSE cells. Apoptosis was assessed by TUNEL on X-gal-stained P1 and P5 ovaries. TUNEL positivity (green) was not observed in the ovary. DNase-treated ovary served as a positive control. Slides were counterstained with PI (red). Scale bar = 50 μm.Back to article page
