Representative images of the tissue selected for miRNA analysis. A: The tissue blocks selected show typical histopathological pattern of usual interstitial pneumonia: patchy distribution of old fibrosis in the form of scar and honeycomb change (boxed area), and new fibrosis in the form of fibroblast focus (arrow), next to nonfibrotic lung parenchyma. Hematoxylin and eosin (H&E) was used. B: An enlarged image of a fibroblast focus depicted by the arrow in A. H&E was used. Original magnification: ×40 (A); ×100 (B).
