Fig. 6From: Water extract of Clinacanthus nutans leaves exhibits in vitro, ex vivo and in vivo anti-angiogenic activities in endothelial cell via suppression of cell proliferationEffect of C. nutans water extract on VEGF-induced capillary-like endothelial tube formation. a Microscopic examination demonstrated C. nutans extract does not suppressed VEGF-induced capillary-tube like formation in comparison with VEGF group. b Capillary-tube like vessel density was calculated and compared. The values presented are the mean ± SEM of three independent experiments. *p < 0.05 were considered significant when compared to normal control (N); #p < 0.05 were considered significant when compared to VEGF alone groupBack to article page
