CD15 expression in human colon tissues. 8a CD15 immunostaining in healthy tissues (A), ulcerative colitis (B), adenomas (C) and adenocarcinomas (D). The figure shows an increasing expression in all the compartments: endothelial, epithelial and stromal. In the AC tissues there is a wide distribution and a strong intensity of the marker (magnification ×400). 8b Expression of CD15 in three different compartment shows that in all groups CD15 is significantly increased respect to healthy tissues (mean ± SEM; **P < 0.01, *** P < 0.001). HT = healthy tissues (N = 16); UC = ulcerative colitis (N = 13), AD = adenomas (N = 34; 29 low and 5 high grade), AC = adenocarcinomas (N = 53; 7 T1, 10 T2, 33 T3, 3 T4).
