Oridonin suppresses the colony forming ability of gallbladder cancer cells. SGC996 and NOZ cells were treated with oridonin (0.75, 1.5, and 3 μmol/L) and were allowed to form colonies in fresh medium for 14 days. The photomicrographic differences (A) and influence of colonies (mean ± SD, n = 3) (B) on colony formation are shown. All data were from 3 independent experiments. *P < 0.05, **P < 0.01 vs. the control group.
