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

Figure 6

The overall BrdU-labeled epithelial cells during porcine lung maturation. The percentage of BrdU cells in the lung over 90 days was accessed by IHC assay with antibody to BrdU. (a) The percentage of BrdU-positive cells in SAE in conducting airway over postnatal days 1, 30, 60, and 90. (b) The percentage of BrdU-positive AT2 cells in the alveolar region of a distal lung at indicated time points was determined by IHC colocalization assay of BrdU/pro-SPC double staining. BI, bronchiole; Br, bronchus; DT, distal trachea; MT, middle trachea; PT, proximal trachea.
