Mesenchymal stem cell-derived extracellular vesicles targeting irradiated intestine exert therapeutic effects.

ABSTRACT: Background: Radiation-induced intestinal injuries are common in patients with pelvic or abdominal cancer. However, these injuries are currently not managed effectively. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have been extensively used in regenerative medicine. However, the results of MSC-EVs in the repair of radiation-induced intestinal damage have been unsatisfactory. We here investigated the nanotherapeutic functions of MSC-EVs in radiation-induced intestinal injury. Methods: We visualized the biodistribution and trend of MSC-EVs through in vivo imaging. A radiation-induced intestinal injury model was constructed, and the therapeutic effect of MSC-EVs was explored through in vivo and in vitro experiments. Immunofluorescence and q
