Percentage of (a) human bronchial and (b) rabbit tracheal ASMCs expressing α-actin, estimated by indirect immunofluorescence with an anti-α-actin antibody after incubation for 72 h with bFGF (10 ng/mL), TGF (20 ng/mL), or PDGF (25 ng/mL). Data are presented as mean ± SEM, and refers to the number of independent experiments. * and *** compared to control (one-way ANOVA with statistically significant differences between groups being determined by Bonferroni’s posttest).
