To investigate the efficiency of adenovirus-mediated gene delivery in regenerating human respiratory epithelium, we have performed infections with an E1- and E3-deleted type 5 recombinant adenovirus containing the Escherichia coli LacZ reporter gene on different culture models of regenerating human nasal polyp surface epithelium. These models included: (i) an ex vivo organ culture of nasal polyp tissue, (ii) an explant outgrowth cell culture, and (iii) an in vitro wound repair model, on dissociated cells. In ex vivo nasal polyp tissue, transduced cells were not detected in normal pseudostratified areas, but were found in areas of the surface epithelium with a morphology reminiscent of regenerating airway tissue. In the explant outgrowth cell culture, adenovirus-infected cells were preferentially detected at the periphery of the outgrowth. These transducible epithelial cells, representative of epithelial cells present in vivo during the process of surface airway epithelium regeneration, were shown to be migrating and poorly differentiated cells, which were proliferating or not. In the in vitro wound repair model, the efficiency of cell transduction was much higher in cells present in the wound area than in those far from the wound area. These results indicate that regenerating cells from human airway surface epithelium represent preferential targets for transgene expression, and suggest that efficiency of CFTR gene transfer by recombinant adenovirus vectors may be higher in regenerating CF airway mucosa than in normal tissue. However, since these cells do not show endogenous CFTR expression, the relevance of their preferential transduction for the functional correction of the ion transport defect in cystic fibrosis needs further investigations.
