XAG inhibits HCC cell growth in vitro. a The chemical structure of XAG. b After Bel 7402 and SMMC 7721 cells were treated with 10 and 20 μM of XAG or vehicle, then the effect of XAG on the morphologic change of HCC cells was observed and photographed by an inverted microscope under 40× magnification. c Bel 7402 and SMMC 7721 cells were treated with 10 and 20 μM of XAG or vehicle for 24 and 48 h, and cell viability was analyzed by CCK-8 assay. Data are presented as mean ± standard deviation (SD) for three independent experiments. **p<0.01
