Abstract:
BACKGROUND: Mesenchymal stem cells (MSCs) from adult bone marrow can alter alloimmune response in vitro and vivo. Their potentiality is great in solid organ transplantation.OBJECTIVE: To develop MSC antirejection therapy and identify behind mechanishm of MSCs immunomodulation ability. METHODS: We searched Pubmed (1994-Mar.2009) with the key words of "mesenchymal stem cells, solid organ transplantation, tolerance, immunosuppression, animal model". RESULTS AND CONCLUSION: Totally 262 English articles about influence and mechanism of action of adult bone marrow mesenchymal stem cells on solid organ transplantation were collected. The 49 suitable articles were included without earlier publication time, repeated and analogous study. Human mesenchymal stem cells did not express MHC2 Ⅱ antigen and T cell costimulatory molecules B7. Coculture with allogenic T lymphocytes could not induce T cell proliferation, but inhibited mixed lymphocyte reaction and mitogenstimulated T cell proliferation. Inhibitory effects of mesenchymal stem cells on T cell proliferation were not limited by major histocompatibility complex. Mesenchymal stem cells no matter from donors or recipients had similar immunoloregulation effects. Allogene mesenchymal stem cells could cause immunereaction in vivo, no complete immune privilege. The in vivo effects of mesenchymal stem cells will strongly depend on their localization and migration pattern after injection. Therefore, MSCs are interesting candidate cells for tolerance induction in clinical organ transplantation.
