Staining of γ-H2A.X in regions with low surface density and high (a) collagen 1 or (b) elastin staining. More extensive γ-H2A.X staining (red) was present in the regions with high elastin content. The bronchial epithelium had extensive γ-H2A.X positive staining in the IPF group, primarily in the airway epithelial cells. c Airway wall from a control subject. d Airway wall from a subject with IPF.
