Smooth muscle cell migration. Representative images of cell migration from 0 to 24 h of postscratch cultivation. Nontreated (a, d), prepolishing (b, e), and postpolishing surfaces (c, f) are depicted. g Image analysis of the cell migration rate, calculated as [(initial scratch area – remaining scratch area during 24-h cultivation)/initial scratch area] × 100. The indicated values are the mean ± SD (n = 5), *p < 0.05
