Figure 10. Radicicol inhibited survival rate of WSU-HN6 and CAL-27 cells. (A, B) Survival rate of WSU-HN6 and CAL-27 cells after coculture for 24, 48, and 72 h with radicicol. (C) Plate clone assay to assess the colony formation ability of two cell lines under different concentrations of radicicol. *p < 0.05, **p < 0.01, ***p < 0.001, compared with 0 μM; n = 3.
