Abstract:
Objective To explore the effect of chimera on acute graft-versus-host disease (aGVHD) after xenogeneic bone marrow transplantation. Methods Chimera was produced by exposing rats to sublethal total body irradiation and mouse bone marrow transplantation plus intraperitoneal injection of CTX. Mice were divided into three groups. Mice in group A were transplanted with marrow cells of rats without chimera, mice in group B with marrow cells with chimera, and mice in group C with C57BL/6 of rat marrow cells with chimera. Prophylactic effect on the model of aGVHD in the mice induced after xenogeneic bone marrow transplantation was observed. Results All transplantated mice showed typical aGVHD signs. Animals in group A developed typical aGVHD, and death occurred in 10-12 days after transplantation. The mean survival time of group B were longer than that of group A and C, and the signs and histopathological changes of aGVHD in group B were less severe. Conclusion Xenogeneic chimera can prevent aGVHD, alleviate its symptoms and histopathological changes, and prolong mean survival time. The prophylactic effect is specific.
