Gli2 expression is decreased in AEC from COPD patients. a. Representative micrograph showing a ROI of a bronchial brushing stained for Gli2 (Gli2, red) and cell nuclei (DAPI, blue) in both non-COPD (upper panel) and COPD patients (lower panel). Magnification corresponding to the selected area is shown. b. Dot plot with median showing the total percentage of Gli2-positive cells in non-COPD (n = 15) and COPD patients (n = 15). *, p < 0.05
