n-Butylidenephthalide (BP) inhibited PDGF-induced phenotypic switch. Measurements of morphology and protein expression in A7r5 treated with BP: (A) Representative images of PDGF-induced A7r5 in the absence or presence of BP (25 and 75 μg/mL) for 24 h. Scale bar = 50 μm; (B,C) Western blotting analysis of phenotypic marker expression. All data are presented as the means ± standard deviation of three independent experiments. * p < 0.05 and ** p < 0.01 versus the PDGF group.
