A, Gene expression of fibrosis and fibrosis-related pathway markers after 48 hours: Col1α1, αSma, Hsp47, Fn2, C-myc, Pai-1, and Ctgf with or without TGF-β1(5ng/mL). The broken line is the normalized control at 0 hours (value = 1) for the 48 hour bars; the broken line is also the normalized control of 48 hours without TGF-β1 (value = 1) for the 48 hours with TGF-β1 (5ng/mL) bars. B, Protein expression of PDGFR during culture. Data are expressed as mean +/- SEM (n = 3–8). One-tailed Student t test; *P < 0.05, **P < 0.01 vs control 0 hours or 48 hours.
