Histopathological characterisation of resected trachea: periodic acid Schiff staining showed comparable GAG staining to controls in (a) mucosa, (b) cartilage, and (c) pericartilagenous junctions. Lysosomal LAMP1 staining showed no additional staining intensity in (d) epithelium or (e) chondrocytes, however, (f) chondrocyte lacunae were markedly larger in diameter.
