IL-13 mediates airway epithelial repair. Injured monolayers of 1HAEo− cells were treated with different concentration of (A) shIL-13Rα2.FC (1–10 μg/ml) or (B) IL-13 (1–100 ng/ml) immediately after injury or kept in serum-free medium, and corresponding wound areas were determined. Data are mean ± SEM for eight wounds in each group. *P < 0.05, ‡P < 0.01.
