dc.description.abstractBACKGROUND: Sepsis is a global inflammatory disease that causes death. It has been reported that mesenchymal stem cell (MSC) treatment can attenuate inflammatory and septic symptoms. In this study, we investigated how interactions between neutrophils and human umbilical cord blood (hUCB)-MSCs in the liver of septic mice are involved in mitigating sepsis that is mediated by MSCs. Accordingly, we aimed to determine whether hUCB-MSC application could be an appropriate treatment for sepsis. METHODS: To induce septic condition, lipopolysaccharide (LPS) was intraperitoneally (i.p.) injected into mice 24 h after the intravenous (i.v.) injection of saline or hUCB-MSCs. To determine the effect of hUCB-MSCs on the immune response during sepsis, histologic analysis, immunoassays, and two-photon intravital imaging were performed 6 h post-LPS injection. For the survival study, mice were monitored for 6 days after LPS injection. RESULTS: The injection (i.v.) of hUCB-MSCs alleviated the severity of LPS-induced sepsis by increasing IL-10 levels (p < 0.001) and decreasing mortality (p < 0.05) in septic mice. In addition, this significantly reduced the recruitment of neutrophils (p < 0.001) to the liver. In hUCB-MSC-treated condition, we also observed several distinct patterns of dynamic interactions between neutrophils and hUCB-MSCs in the inflamed mouse liver, as well as vigorous interactions between hepatic stellate cells (HSCs or ito cells) and hUCB-MSCs. Interestingly, hUCB-MSCs that originated from humans were not recognized as foreign in the mouse body and consequently did not cause graft rejection. CONCLUSIONS: These distinct interaction patterns between innate immune cells and hUCB-MSCs demonstrated that hUCB-MSCs have beneficial effects against LPS-induced sepsis through associations with neutrophils. In addition, the immunomodulatory properties of hUCB-MSCs might enable immune evasion in the host. Taken together, our results suggest the prospects of hUCB-MSCs as a therapeutic tool to inhibit inflammation and alleviate pathological immune responses such as sepsis.-
