Phenotypic Analysis of BrdU Label-Retaining Cells during the Maturation of Conducting Airway Epithelium in a Porcine Lung

Figure 4

Immunohistochemistry staining of BrdU-labeled epithelial cells in porcine tracheal epithelium. Representative images of IHC staining of colocalization of BrdU and epithelial cell type marker keratin 14 and mucin 5AC in the trachea of porcine at day 1 post BruU pulse. (a, b) Colocalization of keratin 14 (brown) and BrdU (red) in the proximal (a) and middle (b) trachea of a pig lung determined by IHC. (c, d) Colocalization of mucin 5AC (brown) and BrdU (red) in the proximal (a) and middle (b) segments of the trachea in a pig lung determined by IHC and counterstained with hematoxylin (blue). Bar = 50 μm.
