Transfer of the Active Form of Transforming Growth Factor-β1 Gene to Newborn Rat Lung Induces Changes Consistent with Bronchopulmonary Dysplasia

Bronchopulmonary dysplasia is a chronic lung disease of premature human infancy that shows pathological features comprising varying sized areas of interstitial fibrosis in association with distorted large alveolar spaces. We have previously shown that transfer of active transforming growth factor (TGF)-beta 1 (AdTGF beta 1(223/225)) genes by adenovirus vector to embryonic lungs results in inhibition of branching morphogenesis and primitive …
