Whole lung mince digested with collagenase IV from control unchallenged animals or chronic CRA allergen-challenged animals was cultured in six-well plates for 48 hours and analyzed by circulation cytometry for manifestation of TERT (A), TERT and c-kit (B), or -clean muscle mass actin (-SMA) (C) as described

Airway swelling, airflow obstruction, and bronchial hyperresponsiveness are characteristic phenotypic features of asthma. Clinically, airflow obstruction in asthma often is not fully reversible, and many asthmatic patients encounter an accelerated and progressive loss of lung function throughout time.1 This is accompanied by peribronchial eosinophil accumulation with mucus hypersecretion and structural changes characterized by an increase in smooth muscle mass and subepithelial fibrosis. These changes…
