Relative expression of TGF-β1, FGF10, and PDGF in patients. (A) The quantification of microarray results, TGF-β1 and FGF10 were relatively higher in IPF, while PDGF was highly expressed in INSIP; (B) the expression of above genes in INSIP and IPF were confirmed by RT-PCR, and the experiment was independently repeated three times, *P<0.05. TGF-β1, transforming growth factor-beta-1; FGF10, fibroblast growth factor 10; PDGF, platelet derived growth factor; INSIP, idiopathic nonspecific interstitial pneumonia; IPF, idiopathic pulmonary fibrosis; RT-PCR, reverse transcription polymerase chain reaction.
