Research Progress of Xenotransplantation

Objective To summarize the research progress of xenotransplantation. Methods Domestic and international publications about xenotransplantation were summarized and reviewed. Results Hyperacute xenograft rejection was a huge problem for xenotransplantation,but it could be alleviated if the organs or tissues of donor were genetically modified. So far the graft survival time differed greatly due to characteristics of different organ. Conclusions By reviewing the studies of relevant papers about xenotransplantation,a comprehensive understanding of research background and a suitable research direction of xenotransplantation can be supplied. The graft organs or tissues from genetically modified donors are expected to avoid or alleviate hyperacute xenograft rejection.
