Fig 6. Distribution of NMBR in pig respiratory system and circulatory system.

Fig 6

Immunohistochemical staining of NMBR in the trachea (A), lungs (B), aorta (C) and heart (D). High NMBR-positive cell magnification in the pseudostratified ciliated columnar epithelium of the trachea (1) (denoted by an arrow) and in tracheal glands of the tracheal submucosa (2) (denoted by an arrow) (a); the visceral pleura (1) (denoted by an arrow), the alveolar epithelium cells (2) (denoted by an arrow), the pulmonary alveolar macrophage (3) (denoted by an arrow) (b1), and the simple columnar ciliated epithelium of the terminal bronchiole (1) (denoted by an arrow) (b2); the nerve (1) (denoted by an arrow) (c1) and elastic fibers of tunica media in the aorta (1) (denoted by an arrow) (c2); cardiac cells (1) (denoted by an arrow) in the heart (d). Negative controls in the trachea (A0), lungs (B0), aorta (C0) and heart (D0). Scale bars in (A, B, C, A0, B0, and C0) = 100 μm, (D and D0) = 50 μm, (a, b1, b2, c1, c2 and d) = 20 μm.
