Fibrotic mediator proteins released from endothelial cells. Protein levels of TGF-β1 (a), CTGF (b) and PDGF-C (c) were quantified by ELISA. Concentrations of TGF-β1, CTGF and PDGF-C were significantly higher in the culture medium of endothelial cells from bleomycin-treated lungs, compared with those from saline-treated lungs. Data are means ± standard error of the mean for three to six mice. *p < 0.05, **p < 0.01, compared with saline-treated mice
