Histopathology of mutant lungs. Sections of wild type (A,D), nm1054 (B,E), and bgh (C,F) lungs through the major airway showing an absence of major defects in either mutant. High magnification images (D–F) show that cilia are present on the epithelial surface of both mutants. Sections are stained with hematoxylin and eosin. Scale bars represent either 500 (A–C) or 50 (D–F) μm.
