[Animal model of rat-to-mouse xenogeneic bone marrow transplantation with graft-versus-host disease].
To observe the graft-versus-host disease (GVHD) in rat-to-mouse model of bone marrow transplantation to build a GVHD model, BALB/c mice were conditioned with 8.5 Gy lethal total body irradiation and divided into two groups. One group of mice was infused with 4 x 10(7) bone marrow cells (BMC) from SD rats. The other group of mice was infused with 4 x 10(7) bone marrow cell and 2 x 10(7) spleen cells from SD rats. GVHD in mice of two groups were observed for 60 days. The results showed that mice in the group infused with only BMC mostly (80%) survived more than 60 days, but in the other group infused with mixed BMC and spleen cells, all mice died within 14 days and showed GVHD with pathologic evidence. In conclusion, to induce GVHD in rat-to-mouse bone marrow transplantation needs additional rat spleen cells.
