Prednisolone inhibits SaOS2 osteosarcoma cell proliferation by activating inducible nitric oxide synthase

Figure 1 Prednisolone inhibits the growth of SaOS2 but not of U2OS. A: Viable SaOS2 cells were counted after 4 d in the presence of different concentrations of prednisolone (^aP < 0.05; ^bP < 0.01); B: Viable U2OS cells were treated as above and counted after 96 h (^aP < 0.05). Results are shown as the mean of three separate experiments ± SD. CTR: Control.
