Microvesicles derived from mesenchymal stem cells inhibit acute respiratory distress syndrome-related pulmonary fibrosis in mouse partly through hepatocyte growth factor

Figure 2 Microvesicles derived from mesenchymal stromal cells homing detection by the near-infrared dye NIR815. At 24 hours after injection with mesenchymal stromal cell-derived microvesicles (MSC-MVs), the fluorescence appears mainly yellow in lung, and at 72 hours after injection, the fluorescence appears mainly yellow and red with significantly increased fluorescence intensity.
