Figure Lengend Snippet: hAECs ameliorated multiple organ damage of CLP mice. (A) Serum creatinine, alanine aminotransferase, and aspartate aminotransferase concentrations at different times in mice with CLP operation followed by vehicle ( n = 5) or hAECs ( n = 5) injection. * P < 0.05 vs. the CLP + vehicle group. (B) Renal pathology of septic mice at 16 h after CLP or CLP with hAECs treatment. Representative micrographs from each group are shown. The arrows indicate tubular epithelial vacuolization and the loss of brush border and the asterisks indicate Bowman’s capsule expansion (H&E staining; scale bar = 50 μm). The lesions in the kidney were alleviated by the hAECs treatment. (C) Pathology of liver, heart, and lung of septic mice at 16 h after CLP or CLP with hAECs treatment. Representative micrographs from each group are shown. The blue arrows indicate vacuolization of hepatocyte cytoplasm and the blue arrowheads indicate sinusoidal congestion of liver tissues. The red arrows indicate edema and vacuolization of myocardial cells of heart tissues. The black arrows indicate alveolar congestion and hemorrhage. The black arrowheads indicate infiltration or aggregation of neutrophils in airspaces of lung tissues (H&E staining; scale bar = 50 μm). The lesions in the liver, heart, and lung were alleviated by the hAECs treatment. (D) Organ pathological scores representing the degree of lesion damage at 16 h after CLP. * P < 0.05, ** P < 0.01, *** P < 0.001 vs. the sham group; # P < 0.05, ## P < 0.01, ### P < 0.001 vs. the CLP + vehicle group.
