Figure 3.

Expression, as assessed by antibody based immunoperoxidase methodology, of Fz1/2 receptors in (A1–3) normal colonic mucosa, (B1–3) well differentiated colon carcinoma, and (C1–3) poorly differentiated colon carcinoma. Haematoxylin and eosin staining is depicted in A1, B1, and C1. Experimental conditions are represented in panels A2, B2, and C2 (original magnification, ×40) and A3, B3, and C3 (original magnification, ×100). The brown granular staining in panels C2 and C3 indicates the presence of Fz1/2 receptors.
