Human Umbilical Cord-Derived Mesenchymal Stem Cells Alleviate Acute Lung Injury Caused by Severe Burn via Secreting TSG-6 and Inhibiting Inflammatory Response

Figure 2

Effect of TSG-6 on the structural damage and total inflammatory cell infiltrations of lung tissues induced by severe burn. Representative photographs of lung tissues in all groups using H&E staining are shown (the light microscope, 400x).
