Evaluation of the apoptosis of pulmonary vascular endothelial cell in the LPS injured lung after the MSC or MSC-ShVEGF infusion by TUNEL assay. (a) Representative images of the apoptosis of lung endothelial cells in the LPS injured lung in different groups at 24 hours after the MSC treatment (×400). (b) The quantitative result of the apoptosis index of lung endothelial cell in the LPS injured lung in different groups at 24 hours after MSC injection (; versus control group, versus ALI + PBS group, and versus ALI + MSC group).
