Abstract:
To investigate the effect of bone marrow mesenchymal stem cells (BMMSC) on acute graft versus host disease (aGVHD) and graft versus leukemia (GVL) after allogeneic bone marrow transplantation (allo-BMT), both bone marrow cells and BMMSC obtained after three to four weeks of culture from donor mice were transplanted into the recipient mice injected with acute lymphocytic leukemia cells 5 days before, the control group was injected with bone marrow cells alone. The survial time after allo-BMT was recorded; the general manifestation and pathological changes of aGVHD in recipient mice were observed; the effects of BMMSC on the quatity of CD4(+) and CD8(+) T cell in vivo after allo-BMT were evaluated by flow cytometry; chimerism was detected by sex chromosome. The results showed BMMSC could increase obviously the survival time, and delay onset of aGVHD, BMMSC could decrease the amount of CD4(+) T cell and increase CD8(+) T cell in vivo. It is concluded that cotransplantation of bone marrow cells with BMMSC from the same donor mice has GVL effect. BMMSC can alleviate aGVHD and maintain GVL effect after allo-BMT.
