Core Tip

Core tip: In this paper, transplant recipient rats were pretreated with bone marrow mesenchymal stem cells (BMMSCs) in advance, and these rats were in a compromised immune state. CXCR3/HO-1 gene modified BMMSCs were injected into recipient rats after small bowel transplantation. The survival time of these rats was significantly prolonged; the number of cells that underwent apoptosis was significantly lower in the CXCR3/HO-1 modified BMMSCs group compared with rats from the HO-1 gene modified BMMSCs group, the native BMMSCs group, and the NS group. Furthermore, the percentage of regulatory T cells was significantly increased. Proinflammatory cytokines (IL-2, IL-6, IL-17, IFN-γ, and TNF-α) were significantly reduced, while anti-inflammatory cytokines (IL-10 and TGF-β) were significantly increased. Our data suggest that BMMSCs modified with the CXCR3 and HO-1 gene can reduce rejection of the small intestine more effectively than HO-1 modified BMMSCs and native BMMSCs.
