C: intratracheal instillation of 50 μL of saline, E: intratracheal instillation of 0.1 UI of pancreatic porcine elastase (PPE), SAL: injection of 50 μL of saline, BM-MSC: bone marrow mesenchymal stromal cell (1 × 105) administration; AD-MSC: adipose tissue derived mesenchymal stromal cell (1 × 105) administration; L-MSC: lung derived mesenchymal stromal cell (1 × 105) administration; IV/IT: intravenous or intratracheal injection 3 h after the last instillation of saline or PPE; ♦: saline or PPE instillation; ★: all data were analyzed at day 28.
