Comparison of the consequence of liraglutide alone, three MSCs alone, and combination of liraglutide in ALI models. a The lung tissue sections were observed by H&E staining for histological after 2d of LPS stimulation. The representative sections were showed at × 20 original magnification. b Lung injury score, c lung wet-to-dry, and d total protein concentration in BALF were assessed. e Total cells, f macrophages, and g neutrophils in BALF were assessed by Wright-Giemsa composite dyeing stain counting. Each group contains 6 mice. Error bars represent mean ± SD from three independent experiments. Scale bars, 100 μm. Compared with the PBS + PBS group, ***P < 0.001; compared with the LPS + PBS group, ⁺P < 0.05, ⁺⁺P < 0.01, and ⁺⁺⁺P < 0.001; compared with the corresponding MSC group, ^#P < 0.05, ^##P < 0.01, and ^###P < 0.001
