ICG-001 inhibits gastric cancer stem-like cells self-renewal properties. a ICG-001 inhibited the colony formation capacity and b tumor sphere formation capacity in four cell lines. Representative photograph of colony and tumor spheres were shown on the left. Statistical analysis was shown on the right. Several gastric stem cell markers expression were measured by c qRT-PCR and d flow cytometry. Data are the mean ± SEM of three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001 vs. control
