Chinese Researchers Achieve First-Ever Pig Liver Transplant in a Human

A team of researchers in China has successfully performed the first-ever transplant of a pig liver into a human, marking a significant scientific milestone recently announced. While this experiment is part of a broader series of efforts to transplant animal organs into humans, it remains an early step in a long journey of research and development.

The significance of this procedure lies in its potential to open new avenues in the field of organ transplantation. However, the results currently have no direct medical benefit, as the patient was declared brain-dead at the time of the operation.

The surgery, conducted on March 10, 2024, involved the transplantation of a genetically modified pig liver designed to increase the likelihood of success. The transplanted liver functioned for ten days before the experiment was ended at the request of the patient’s family. Notably, the patient’s original liver was not removed, in what is known as an “auxiliary” transplant—using the animal organ as a temporary support until a suitable human donor is found.

Researcher Lin Wang stated that the transplanted liver responded very well, producing bile and albumin without complications. Nevertheless, some experts who were not involved in the study expressed cautious views. Despite the experiment’s importance, they emphasized that it should not be taken as proof that pig livers could replace human livers in the near future. Professor Peter Friend, a transplant specialist, noted that the findings provide valuable insight into transplantation techniques but do not indicate that pig organs can serve as viable human replacements anytime soon.

This experiment follows years of research into the possibility of transplanting pig kidneys and hearts into humans. While some of these attempts have failed, one successful case occurred in November 2024, when a pig kidney was transplanted into a patient who remains alive. However, the liver poses a far greater challenge due to its complex functions compared to the heart or kidneys—highlighting the depth and difficulty of research in this area.
