Objective To review the current condition, test method and progress of the animal model of xeno graft versus host disease(xeno GVHD). Methods The literature review and comprehensive analysis methods were used in this article. Results Implanted immunologic cells, the recepient had the chance of showing host versus graft reaction, GVHD or microchimerism. Now, xeno GVHD could be induced in vivo at small and large animals, it also could be supervised through many ways. Conclusion Chimeric cell is very important to xeno-GVHD animal model. With this model, we can really mimic the immunologic change in vivo after xenotransplantation.
