Effects of TQ on the expression of α‐SMA and Ki‐67. Serum‐starved VSMCs were stimulated with 40 ng/mL PDGF‐BB in the presence or absence of TQ (5‐15 μmol/L) for 24 h. A, C, the expression of α‐SMA was determined by immunofluorescence staining (scale bar = 50 µm). Means ± SD (n = 6 in each group). *P < .05 vs control, #P < .05 vs PDGF‐BB. B, D, The expression of Ki‐67 was determined by immunofluorescence staining (scale bar = 10 µm). Means ± SD (n = 9 in each group). *P < .05 vs control, #P < .05 vs PDGF‐BB
