A 62-year-old American man, Richard Suleiman, performed a kidney transplant from a pig in a global medical precedent.
During the four-hour operation, a team of surgeons transplanted a pig-derived kidney into the body of Suleiman, who was suffering from kidney failure.
Two weeks after the operation, Suleiman left the hospital after recovering.
Although he suffered from type II diabetes and high blood pressure, the surgery team confirmed that there was no evidence to suggest that his sudden death was caused by the operation.
Prior to this operation, Suleiman had been on dialysis for many years, and then received a kidney transplant from a human donor in December 2018.
However, the kidney began failing after about 5 years, prompting him to resume dialysis in May 2023.
The pig-grown kidney was genetically modified to improve its compatibility with humans, removing harmful genes and adding certain human genes.
This achievement is an important step towards solving the problem of organ donor shortages, and opening new horizons for treatment and advanced medical technologies.
