Since TGF beta is critical in the pathogenesis of IPF and HGF, FGF7, and FGF10 are important in alveolar epithelial repair, we evaluated the effect of TGF beta on regulating HGF, FGF7, and FGF10 in both control and IPF human fibroblasts. This evidence concerns the gene FGF10 and idiopathic pulmonary fibrosis.
