The mechanism of Adenovirus (Ad) and Adeno-associated virus (AAV) vector-mediated gene transduction in murine tracheae has not been fully understood. Excised tracheae from mice were exposed to either Ad vector (Ad-CMV-LacZ) or AAV vector (AAV-CMV-LacZ) for 1 hour. LacZ gene expression in tracheal epithelial cells was detected by X-gal staining. Only patch distributions of LacZ expressing cells were observed. The percentage of LacZ expressing cells to total cells was less than 1% with either vector. Ad-mediated LacZ transduction was increased by mechanical damage using forceps. AAV-mediated gene transduction in tracheal epithelial cells was also increased by mechanical damage. Furthermore, this increased expression of vector LacZ by damaged epithelial cells was not affected by pretreatment with anti-ICAM-1 mAb or platelet-activating factor receptor antagonist. Although the Ad and AAV vectors were inefficient in transferring genetic material to murine trachea ex vivo, our results suggest that mechanical damage can enhance their transduction efficiency.
