Cigarette smoke alters primary human bronchial epithelial cell (PBEC) differentiation at air-liquid interface (ALI) and induces expression of CD105 a…

Dys-regulation of airway epithelial cell function related to cigarette smoke exposure plays an important role in the pathophysiology of COPD. CD105, a component of TGF-β complex, and CD146, an epithelial-mesenchymal transition inducer, are adhesion molecules involved in cellular proliferation, differentiation, transmigration and tissue remodelling. After validation of an ex vivo ALI culture of PBEC, we assessed the effect of long-term cigarette smoke extract (CSE) exposure on epithelium regeneration and differentiation. Endobronchial biopsy specimens (EBBs) were obtained from 8 controls (C) and 9 COPD. ALI cultures from EBBs of C were exposed to CSE for 7, 14, 21 days. Transepithelial Elect…
