Cellular response to pro-fibrotic stimulus. Paired vocal fold fibroblasts (VFF) and oral mucosa fibroblasts (OMF; n = 4) were exposed to TGF-β1 (5 ng/mL) or vehicle (“C”) and expression of (A) α-smooth muscle actin (ACTA2) and (B) interleukin 6 (IL6) was analyzed 24 h and 72 h later. TGF-β1 effects were analyzed by paired t-test.
