Abstract

In inherited disorders such as surfactant protein deficiencies or cystic fibrosis (CF), where lung damage develops progressively after birth, gene replacement is best accomplished in the neonatal period. We use the adeno-associated virus (AAV) as a vector for gene transfer in the newborn rabbit lung where stem cells are activated for lung growth and differentiation. AAV-mediated gene transfer as assayed by lacZ gene expression occurred preferentially in alveoli in the alveolar epithelial progenitor cell, the type II cell, and in the large airway tracheobronchial based and ciliated cells. Cell proliferation was confirmed by 5-bromo-deoxyuridine (BRDU) labeling in regions undergoing alveolarization and airway branch points. Regions of cell proliferation coincided with areas of significant lacZ expression. Thus, dividing and differentiating cells can be targeted by AAVlacZ delivery to newborn lung.
