Figure 3From: Effect of estradiol on proliferation and differentiation of side population stem/progenitor cells from murine endometriumExpression of ESR1 in SP and non-SP cells. Figure 3A. Immunocytochemical analyses of ESR1 expression in SP and non-SP cells. Nuclear Hoechst staining (blue) and immunofluorescent labeling of ESR1 (green) were merged. Scale bar, 100 μm. The arrows indicate ESR1 immunopositive cells (Hoechst and ESR1 staining merged). Figure 3B, C. RT-PCR analyses of ESR1 expression in SP and non-SP cells. 1. SP Actin; 2. Non-SP Actin; 3. SP ESR1; 4.
