Exogenous S100A8 protein inhibited PDGF-induced proliferation in ASMCs. a ASMCs proliferation was measured using colorimetric-based proliferation assay. b Real-time cell proliferation was measured using the impedance-based xCELLigence proliferation assay, for which the statistical analysis was performed at 72 h time point. Data are expressed as mean ± SD derived from three different set of experiments; **P < 0.01 compared with control; ^#P < 0.05, ^##P < 0.01 compared with PDGF group. The inset table presents cell-doubling times of each group
