SE, CR, and CCT treatments (Table 1) decreased the vessel count (CD31-positive endothelial cells) by 2% (P > 0.05), 12% (P > 0.05), and 30% (P < 0.01) with respect to control, while in the 22rv1 tumor model the vessel count was reduced by 18% (P > 0.05), 29% (P < 0.05), and 44% (P < 0.001) (Table 2). This evidence concerns the gene PECAM1 and neoplasm.
