From: β-catenin/Tcf-signaling appears to establish the murine ovarian surface epithelium (OSE) and remains active in selected postnatal OSE cells

Figure 1

Coelomic epithelium overlying the indifferent gonad displays ß-catenin/Tcf-mediated lacZ expression. Panel A: Whole-mount X-gal staining of E11.5 urogenital ridge. LacZ positive cells overlie the medio-lateral surface of the indifferent gonad (dotted line demarcates the gonad). The mesonephric duct (MD) and mesonephric tubules (MT) also stain for lacZ. Arrowhead indicates coelomic epithelium extending beyond the gonad is not stained. Scale bar = 10 μm. Panel B: Section of an X-gal stained E11.5 urogenital ridge. LacZ staining is present in the gonadal surface epithelium (arrows), cells beneath the surface and the mesonephric ducts (black arrow head). Germ cells (white arrow head) do not stain for lacZ. Scale bar = 50 μm.
