Figure 2From: The role of uPAR in epithelial-mesenchymal transition in small airway epithelium of patients with chronic obstructive pulmonary diseaseUrokinase plasminogen activator receptor (uPAR) immunostaining in small airways epithelium of patients with COPD. (A) uPAR staining in the epithelium of small airways from non-smokers (a), smokers (b), non-smokers with COPD (c) and smokers with COPD (d) (original × 200). (B) Quantification of uPAR protein levels in the small airways epithelium. The mean staining density in small airways.Back to article page
