Regions of Interest (ROI) were selected using immunofluorescence markers for cytokeratin (green), smooth muscle actin (yellow), CD45 (red), and DAPI (blue) to highlight the different cellular and extracellular characteristics of each area of interest. Representative areas of normal lung (A), fibroblastic foci (B) and areas of dense fibrosis (C) were selected from 2 cases with a high density of p16-positive foci. Scale bar = 100 µm
