respiratory system
• late lung development is blocked such that lungs appear more cellular and contain immature alveoli and reduced airspace in distal lungs at E18.5 compared to wild-type
• marker analysis indicates that bronchiolar epithelial progenitor cell differentiation is impaired, however alveolar epithelial cell differentiation appears normal
• bronchiolar epithelial progenitor cell differentiation is impaired
• Clara cell numbers are reduced in E18.5 lungs
• lungs are smaller at E15.5
• distal airways are composed of highly disorganized cells
• enlarged airways in the lungs at E15.5

integument
• fail to develop ventral skin
