• the tracheal epithelium is thicker
• however, no difference in cell density is seen in the tracheal epithelium

• mice appear normal at birth and show normal life span, show normal results in skeletal X-ray, body composition, ECG, hematology, blood biochemistry, urinalysis, and glucose tolerance test
|
• mice exhibit a transient tracheal epithelial hyperplasia during airway repair after injury (isogenic tracheal subcutaneous transplantation), showing a thicker epithelium associated with greater proliferative and basal cells, as well as thickening of the connective tissue and fibroblast layer between the epithelium and tracheal cartilage at day 10 after transplantation
• however, repair of tracheal transplant-related epithelial injury is similar to wild-type mice, with mice showing similar severity of epithelial injury, apoptosis, and cell spreading as in wild-type mice
