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

Figure 7

The percentage of BrdU-labeled keratin 14 basal epithelial cells in conducting airway during porcine lung maturation. The percentage of BrdU-labeled keratin 14-positive cells in the lung over 90 days was accessed by IHC colocalization assay with antibodies to BrdU and keratin 14. (a) The percentage of BrdU/keratin 14 double positive cells in total cells of SAE in indicated regions of conducting airway over postnatal days 1, 30, 60, and 90. (b). (a) The percentage of BrdU/keratin 14 double positive cells in total cells of SMGs beneath the SAE in indicated regions of conducting airway over postnatal days 1, 30, 60, and 90. BI, bronchiole; Br, bronchus; DT, distal trachea; MT, middle trachea; PT, proximal trachea.
