Regulatory changes in China on xenotransplantation and related products.

BACKGROUND

Given the persistence and the worldwide shortage of organs from both the deceased and living donors for clinical transplantation, pig organs or tissues hold immense promises for the patients on the waiting list, and xenotransplantation is deemed as one of the solutions to the organ shortage crisis. Indeed, the emerging gene editing technologies, such as CRISPR/Cas9, have led to tremendous progress in the generation of genetically modified pigs to overcome many barriers associated.

METHOD

We presented a description of the xenotransplantation regulations in China and the related products.

RESULT

Several groups in China have successfully generated transgenic pigs with the elimination of immune rejection or coagulation-related genes, and both pre-clinical and clinical studies have been reported. However, the pre-clinical evaluation and clinical application of porcine xenotransplantation raises ethical and regulatory considerations. Herein, in this review, we will summarize and discuss the progress in xenotransplantation in China and xenotransplantation-related products from the regulatory perspective.

CONCLUSION

There has been remarkable progress in both the genetically modified pigs and pre-clinical studies in China, and China will be the first country to successfully fulfill the xenotransplantation from pig organ to human in the near future.
