Itga3tm1Hap/Itga3tm1Hap Tg(SFTPC-rtTA)5Jaw/? Tg(tetO-cre)1Jaw/? mice exhibit increased bronchoalveolar lavage cellularity at baseline and after bleomycin injury

respiratory system
• cellularity in BAL fluid is almost double that of controls in mice with cre induction
• increase in cellularity is also found after bleomycin injury of the lung
• there is about a 2-fold increase in the number of type II alveolar cells present in the lungs of mice treated with doxycycline
• alveolar septa are thickened with increased deposition of collagen IV in mice with cre induction
• bleomycin injury of the lungs leads to less fibrosis three weeks later due to impaired myofibroblast accumulation and reduced type I collagen response
• the number of myofibroblast per field is 4-5 fold less than in controls after bleomycin injury
• there is a trend towards less compliance in these mice after bleomycin injury than in controls

growth/size/body
• cellularity in BAL fluid is almost double that of controls in mice with cre induction
• increase in cellularity is also found after bleomycin injury of the lung
