Tube formation assay in HUVECs incubated with KFX and PC substance. The morphological changes of the cells treated with different concentrations of KFX and PC substance are observed and photographed using a digital microscope. a Blank control (untreated), b KFX (0.1 mg/mL), c KFX (1 mg/mL), d KFX (2 mg/mL), ePC substance (0.1 mg/mL), f PC substance (1 mg/mL), g PC substance (2 mg/mL). Results indicate the endothelial cell tube formation in presence of KFX and PC substance suggesting their pro-angiogenic activities
