Present situation and progress of xenotransplantation at home and abroad / 器官移植

ABSTRACT

Organ shortage has become one of the major challenges hindering the development of organ transplantation. Xenotransplantation is one of the most valuable methods to resolve global organ shortage. In recent years, the development of genetic engineering technique and research and development of new immunosuppressant have provided novel theoretical basis for xenotransplantation. International scholars have successively carried out researches on xenotransplantation in genetically modified pigs to non-human primates or brain death recipients, making certain substantial progresses. However, most of the researches are still in the preclinical stage, far from clinical application. Therefore, according to the latest preclinical experimental research progress at home and abroad, the history of xenotransplantation, the development of gene modification technology, xenotransplantation rejection and immunosuppression regimens were reviewed, aiming to provide reference for subsequent research of xenotransplantation, promote clinical application of xenotransplantation and bring benefits to more patients with end-stage diseases.
