Lung tissue from CAP-exposed (A, C, E) and control animals (B, D, F) at E14.5 (pseudoglandular stage, A, B), E18.5 (saccular stage, C, D) and P40 (alveolarized lung, E, F). H.E.-staining, all images taken at same magnification. E: budding epithelial tube, L: liver, H: heart (myocardium), Br: bronchiole, S: saccule, AD: alveolar duct. Alveoli appear enlarged in the CAP-exposed group at P40.
