Effect of transforming growth factor beta and bone morphogenetic proteins on rat hepatic stellate cell proliferation and trans-differentiation

Figure 1 Regulating effect of TGF-β1, BMP-2 and BMP-4 on the proliferation of rat hepatic stellate cells. Hepatic stellate cells were incubated with TGF-β1 (A), BMP-2 (B) and BMP-4 (C) as described in Materials and methods. The data represent mean ± SE from ten wells. The experiments were repeated two times. Denotes: a represents ^aP < 0.05 vs the concentrations of 0.1, 0.5 and 1 ng/mL, b means ^bP < 0.01vs the concentrations of 0.1, 0.5 and 1 ng/mL.
