Epithelial turnover in duodenal familial adenomatous polyposis: A possible role for estrogen receptors?

Figure 7 Co-expression of ER-β and caspase 3 is clearly shown in normal tissue. A: Nuclear ER-β expression in a normal villous area (red signal); B: Nuclear caspase 3 expression in a normal villous area (green signal); C: Merge of the two signals and counterstaining with TOPRO 3 (blue signal): magnification at × 1000; D: Nuclear ER-beta expression in the HGD area (red signal); E: Nuclear caspase 3 expression in the HGD area (green signal); F: Merge of the two signals and counterstaining with TOPRO 3 (blue signal): magnification at × 400.
