Expression of ER-α in EC. Representative sections of the superficial (Block 1), deep (Block 2) and extra-tumoral portion (Block 3) of EC were stained with anti-ER-α antibody and compared with stained sections of nonmalignant endometrial specimens (Normal), as seen in the photographs (A). The expression level was examined in epithelial cells (B), stroma cells (C) and the relative expression of both cell types (epithel/ stroma) (D) was calculated. Asterisks mark statistical significance (P < 0.05) compared to nonmalignant endometrial tissue (normal) (X400).
