Because there is the theoretical possibility of an E1a- replication-deficient vector replicating as a result of recombination or complementation with Ad 2/5 E1a sequences present in the target cell , this study is directed toward evaluating respiratory epithelium of normals and individuals with CF for the presence of E1a sequences .
