mortality/aging

premature death ( J:150051 )

respiratory system

respiratory system phenotype ( J:150051 )

N • at E11.5, E14.5 and E18.5, mutant lungs showed normal gross morphology and size relative to control lungs

N • no defects in the branching pattern were detected when E11.5 lungs were cultured for 24 and 48 hrs

N • distal epithelium differentiation (formation of alveolar sacs and type I and type II cells) remained unaffected

N • normal formation of goblet cells was observed in the trachea at birth (P0)

N • the distribution and number of basal cells remained normal

lung inflammation ( J:150051 )

• by P21, isolated foci of inflammatory cells, including macrophages, were seen in the bronchiolar epithelium, unlike in control lungs

abnormal respiratory epithelium morphology ( J:150051 )

• at P7, P14 and P21, a severely attenuated airway epithelium is noted in medium-sized airways and in terminal bronchioles

• at E18.5, the respiratory epithelium was populated almost exclusively by beta-tubulin-expressing ciliated cells, unlike in control lungs where ciliated cells were interspersed with secretory Clara cells

• at E18.5, Foxj1-positive ciliated cells comprised 80-85% of the population of the airway epithelium, regardless of the airway generation, unlike in control lungs where Foxj1-expressing cells averaged 40%, 18% and 17% of epithelial cells seen in the large, medium and small airways, respectively

• at E18.5, Ki67 labeling averaged 15%, 10% and 5% of control values in large, medium and small airways, respectively, suggesting a substantial decrease in epithelial cell proliferation

abnormal bronchiole epithelium morphology ( J:150051 )

• by P21, a thin metaplastic squamous epithelium, scattered cell debris and isolated macrophages were observed instead of the typical cuboidal epithelium seen in control bronchioles

• however, none of these changes were apparent at birth or at E18.5

absent club cells ( J:150051 )

• no secretory Clara cells were detected at E18.5 and P0, as determined by specific marker expression analysis
