Core Tip
Core tip: We evaluated the effects of mesenchymal stem cells (MSCs) on inflammatory bowel disease (IBD). Although MSCs are considered useful therapeutic agents for treatment of IBD, their efficacy has not been immunologically confirmed. We found that MSCs did not exert significant effects and did not restore immune balance or influence levels of interleukins 6 and 10. Recent studies have shown that MSCs may be effective upon local infusion, or in combination with other agents. Therefore, new approaches toward regulation of the immunoregulatory properties of MSCs are required if such cells are to be used to alleviate IBD.
