ICAM1 and neoplasm: The expression densities of the EC markers CD31 (p = 0.002), CD105 (p = 0.002) and CD34 (p = 0.01) were higher on ECs derived from fast-growing B16-F0 tumors, whereas the expression densities of the cellular adhesion molecule CD54 (p<0.05) and CD102 (p = 0.008) were found to be elevated in the slow-growing CT26 tumor (Figure 6C).
