Pathological changes in different groups ([a-e] HE, original magnification ×1000) and lung injury score of pathological change ([f] Smith score). Administrated alone does not cause detectable morphologic change in lung tissue in the mesenchymal stem cell (MSC) group (b) as compared to the control group (a). VT20 caused vascular hyperpermeability and severe neutrophils infiltration, alveolar septae thickened and alveolar bloody effusion in the lung tissue (c). MSCs administration attenuated the lung injury caused by VT20 ([d] MSC+VT20 group; [e] VT20 + MSC group). *P < 0.05 vs. control group; †P < 0.05 vs. VT20 group; ‡P < 0.05, vs. MSC + VT20 group.
