Integrin α9 expression in murine aortic smooth muscle cell (SMC). Serum-starved murine aortic SMC was stimulated with or without platelet-derived growth factor-BB (PDGF-BB) for 24 h. The left panels show representative double immunostaining for α9 (red) and αSMA (green) in SMCs stimulated with or without PDGF-BB. Boxed regions are magnified. Scale bars: 30 μm. The right panel shows the quantification of α9 fluorescence intensity (n = 6/group). Statistical analysis: unpaired Student’s t-test.
