Ultrastructure of the bronchial wall of Adamtsl2−/− mice. (A-F) Ultrastructural analysis of the newborn bronchial wall using TEM. In contrast to WT bronchial epithelium (A,C), the bronchial epithelium in Adamtsl2−/− (−/−) mice is disorganized (B,D,E) and membrane-bound vesicles engorged with granular, electron dense material fill mutant cells and the lumen (E,F). (G-H) The SMC layer of the bronchial wall did not show consistent differences between WT and Adamtsl2−/− mice. (I-J) Higher magnification of the ECM around the bronchial SMCs (from n=4 per genotype). B, Bronchi; Col, collagen fibers; EF, elastic fiber; EP, bronchial epithelium; MF, microfibril.
