Exosomes Derived from Human Umbilical Cord Mesenchymal Stem Cells Relieve Inflammatory Bowel Disease in Mice

Figure 2

Live animal imaging analyses for the homing of ICG-exosomes to colon tissue and spleen of IBD mice. (a) Representative images of exosomes labeled with ICG for 12 hours were detected under live animal imaging system. (b) The IBD mice received intravenous injection of ICG-exosomes for 12 hours and were detected under live animal imaging system (). (c) The colon tissues, spleens, and livers of IBD mice treated with ICG-exosomes were detected under live animal imaging system.
