Specifically, mRNA transcript levels for TGF-β1 were lower in the cultures from IPF patients compared to the ones from healthy donors with ratio of the means 0.001 (p = 0.240), as well as for FGF with ratio of the means 0.000001 (p = 0.0.501). Here, TGFB1 is linked to idiopathic interstitial pneumonia.
