The effect of CTPG on the growth of H22 cells. H22 cells were treated with different concentrations of CTPG. (a) After 24 h, the morphology of H22 cells was observed by inverted microscope. Inserted panels: 20 folds of magnification. (b) After 24, 48 and 72 h, cell viability was detected by MTT assay. (c) The inhibitory rate of CTPG. * p < 0.05; *** p < 0.001 compared to control
