Dose dependent effect of oxidized LDL on VSMCs proliferation by MTT assay. VSMCs at passage 4 were cultured in 96-well plates. Growth medium was replaced by serum-free DMEM for 24 h before VMSC cultures were supplemented with increasing concentrations (0–100 μg/mL) of oxidized LDL for another 24 h. Results were from three experiments and each was performed in triplicate. * p < 0.001 versus the control group
