Inhibitory effects of IVC on the proliferation of different human cancer cell lines. a Structure of IVC. b Various cancer cell lines were incubated with IVC for 48 h, and cell growth was measured by CCK-8 assay. c and d Colony formation assay was performed after MHCC97H cells were treated with IVC at indicated doses, and the number of colonies was manually counted. Original magnification was 40×, scale bars represent 500 μm
