ABSTRACT
To observe whether bone marrow stromal cell line QXMSC1 (H-2(d)) engineered to secrete IL-3 and IL-6 can improved the hematopoiesis in allogeneic bone marrow transplantation (allo-BMT) mice, the stromal cell line QXMSC1IL-3/IL-6 was established by QXMSC1 cells transduced with the recombined retrovirus vector pL3SN containing mouse IL-3 cDNA and pL6SN containing human IL-6 cDNA. The lethally irradiated C57BL/6 (H-2(b)) mice were engrafted with bone marrow cells (1 x 10(7) cells/mouse BALB/c mice, H-2(d)) in which T cells were depleted by anti-Thy1.2 monoclonal antibody adding complement, and QXMSC1IL-3/IL-6 cells (5 x 10(5)/mouse) were co-infused at same time. The hematopoiesis of recipient mice was observed in 20 and 40 days post-transplantation. Blood RBC and WBC were counted, and nucleated cells, CFU-S, CFU-GM, CFU-E and CFU-GEMM were assayed in recipient bone marrow. Results showed that IL-3 and IL-6 were stably expressed in QXMSCQIL-3/IL-6 cells. Compared with BMT and co-infusion with QXMSC1 or QXMSC1 pLXSN cell groups, co-graft with QXMSC1IL-3/IL-6 cells increased the number of blood RBC and WBC in the recipients, and also significantly increased nucleated cells, CFU-S, CFU-GM, CFU-E and CFU-GEMM in recipient bone marrow. It is concluded that the marrow stromal cells transduced with IL-3/IL-6 cDNA improve the hematopoiesis in allo-BMT mice. Co-graft with QXMSC1IL-3/IL-6 cells has synergistic effect in accelerating hematopoietic reconstitution.
