Representative images of DDR1 immunolabeling in colon adenocarcinoma. A. Strong and diffuse staining (red) in adenocarcinoma cells (arrow), (magnification ×10), scored 3+/high; B. Moderate and diffuse staining (red) in adenocarcinoma cells (arrow), (magnification ×20), scored 2+/high; C. Faint staining (red) in adenocarcinoma cells (arrow), (magnification ×10), scored 1+/low. Stromal cell highlighted by an asterisk (*) was weak (A) or negatively (B,C) stained in all cases.
