Sumario: | Mesenchymal stem cell (MSC) therapy is a promising candidate for inflammatory bowel disease (IBD) treatment, while overcoming the limitations of naive seeding cells function and realizing efficient intestinal targeting remains a challenge. Here, a bioadhesive microparticle carrying interleukin‐27 (IL‐27) MSC‐derived extracellular vesicles (MSC(IL‐27) EVs) is developed to treat IBD. The MSC(IL‐27) EVs prepared through lentivirus‐mediated gene transfection technology show ideal anti‐inflammatory and damage repair function. By encapsulating MSC(IL‐27) EVs into dopamine methacrylamide‐modified hydrogel, a bioadhesive EVs microcarrier via microfluidic technology is fabricated. The resultant microcarriers exhibit ideal MSC(IL‐27) EVs sustained release effect and effective wet adhesion property. Furthermore, the therapeutic potential of MSC(IL‐27) EVs‐loaded microcarriers in treating IBD is demonstrated. Through giving IBD rats a rectal administration, it is found that the microcarriers can firmly anchor to the surface of colon, reduce the inflammatory response, and repair the damaged barrier. Therefore, the bioadhesive MSC(IL‐27) EVs‐loaded microcarriers provide a promising strategy for the biomedical application of MSC‐derived EVs, and broaden the clinical potential of MSC therapy. |
