Figure 6. Effect of TGF-β1 and miR-21 on collagen production and mRNA expression in fibroblasts from TAO donors (n=3). Results are expressed as a percentage of untreated control values presented as mean ± standard deviation (SD; *p<0.05 versus transforming growth factor-beta1 (TGF-β) untreated control; #p<0.05 versus anti-miR-21-treated cells). Data are representative of three independent experiments.
