Effects of AT on scratch wound healing in PDGF-BB-stimulated VSMC. VSMC were treated with AT (10 µM and 30 µM) and PDGF-BB (10 ng/mL) for 24 h. (A) Dotted white lines indicate the wounded area from the initial scratches. Magnification, × 200. Bar = 500 µm. The number in the top right of each image is concentration of PDGF-BB/concentration of AT. (B) Amount of migration relative to the untreated control (%). Results are presented as mean ± standard error. Values with the same superscript letter are not significantly different by Duncan's multiple range test (P < 0.05).
