(a) Immunohistochemical staining for VEGF expression in Control + vehicle group (A), Control + CUR (B), CaSki + vehicle group (C), CaSki + CUR500 group (D), CaSki + CUR1000 group (E), and CaSki + CUR1500 group (F). Bar = 10 μm, 200x. (b) The percentage of positive staining (%) and the intensity of VEGF expression (mean ± SEM). ^∗𝑃<0.001 versus Control + vehicle group, ^◆𝑃<0.001 versus CaSki + vehicle group and CaSki + CUR500 group, and ^♣𝑃<0.001 versus CaSki + CUR1000 group.
