英文摘要
In this study, we evaluated the immunological roles of mesenchymal stem cells (MSC) in cancer microenvironment. GFP chimeric mouse models showed that bone marrow-derived MSC migrated to caner tissues and augmented the tumor growth. Human MSC inhibited dendritic cells functions through the production of a variety of immunosuppressive cytokines such as IL6 and VEGF. These results suggested that MSC induced caner immune evasion in the cancer microenvironment and can be an attractive target for the restoration of immune competence of cancer patients.
