Abstract:
Objective Previous study found that ifbroblast growth factor-2(FGF2) expression was at a low level in bone marrow of children with aplastic anemia. In this study, we established a bone marrow failure animal model to investigate whether FGF2 is involved in bone marrow failure. Methods BALB/c mice were irradiated by 5.0 Gy ray, and then infused with 1×106 lymphocytes from allogeneic mice lymph node. Peripheral blood cells and bone marrow mononuclear cells counting and bone marrow pathology were done. FGF2 protein in bone marrow mononuclear cells was measured by ELISA. Results Compared with the control group, the counting of hemoglobin, white blood cell, platelet and bone marrow mononuclear cell in aplastic anemia mouse model were signiifcantly deceased (P<0.05). Moreover, FGF2 expression in aplastic anemia mouse model were signiifcantly reduced (P<0.05). Conclusions 5.0 Gy ray irradiation and then 1×106 lymphocyte infusion in mice can induce bone marrow failure similar to the features of aplastic anemia. The low expression of FGF2 in bone marrow of aplastic anemia patients may play an important role in the pathogenesis of aplastic anemia.
