Adenovirus-mediated decorin gene transfer prevents TGF-β-induced inhibition of lung morphogenesis

Excessive transforming growth factor (TGF)-beta signaling has been implicated in pulmonary hypoplasia associated with bronchopulmonary dysplasia, a chronic lung disease of human prematurity featuring pulmonary fibrosis. This implies that inhibitors of TGF-beta could be useful therapeutic agents. Because exogenous TGF-beta ligands are known to inhibit lung branching morphogenesis and cytodifferentiation in mouse embryonic lungs in ex vivo …
