Transforming growth factor (TGF)-β1 stimulation decreases migration and invasion of lung fibroblasts. (A) Primary lung fibroblasts pretreated with TGF-β1 for 48 hours had decreased migration (A) and invasion (B), both in the absence and presence of BAL from injured mice. Data are presented as mean (±SEM) fold increase in migration or invasion, normalized to the control fibroblast to media condition (n = 3 mice as source of lung fibroblasts and BAL; *P < 0.05, **P < 0.01, ***P < 0.001).
