A Whole-body fluorescence imaging of C57BL/6 male mice treated with 8 mg/kg labeled MSC-Exo. Images were taken 6 h after tail vein injection. B Quantitative fluorescent imaging of lung, heart, kidney, liver, and spleen from recipient mice receiving labeled MSC-Exo. C Neutralizing antibodies against CD44 reduced hepatic engraftment of MSC-Exo in ALI murine livers. Images were taken at 6 h. Data were the mean ± SD fluorescence; *p < 0.05, **p < 0.001; n = 5. Individual images were presented.
