Expression of PR-B in EC. PR-B expression was assessed in the superficial (Block 1), deep (Block 2) and extra-tumoral (Block 3) portions of EC, as well as nonmalignant endometrial specimens (normal), as seen in the photographs (A). The expression level was examined in epithelial cells (B) and in the stroma cells (C). Asterisks mark statistical significance (P < 0.05) compared to nonmalignant endometrial tissue (normal) (X400).
