title: Potential therapeutic utility of mesenchymal stem cells in inflammatory bowel disease in mice.
abstract: Mesenchymal stem cells (MSCs) were found to provide an effective therapeutic role in inflammatory diseases by modulating inflammatory responses and tissue regeneration by their differentiation ability. The present work sought to demonstrate the potential therapeutic use of MSCs in treating chronic inflammatory bowel disease (IBD) in mice. A new model to induce chronic IBD based on alternative administration periods of Dextran Sodium Sulfate (DSS) was established. Mice were divided into 2 groups; one was treated with MSCs and the other was treated with phosphate-buffered saline (PBS). Assessment of therapeutic efficacy of MSCs was by measuring weight, stool scoring, histopathological examination, and measuring the gene expression of inflammatory markers: Interleukin-23 (IL-23), Tumor necrosis factor-α (TNF-α), Interferon-γ (IFN-γ), and Intercellular adhesion molecule-1 (ICAM-1). The results showed that DSS administration causes bloody and watery stool, weight loss, and altered histopathologic picture. MSC treated mice showed a significant improvement in stool condition, weight gain, and normal histopathologic picture compared to the PBS treated mice. Moreover, gene expressions of inflammatory markers in the intestines of the MSC treated mice were also significantly lower than those of the PBS treated mice. In conclusion, the data here showed that MSCs have a clear potential efficacy in the treatment for IBD, as their immune modulation effects include inhibition in the expression of key inflammatory markers that each plays an important role in the pathogenesis of IBD.
