Genetically modified pig kidney sustains patient for nine months
A 66-year-old man with end-stage kidney failure received a genetically modified pig kidney in January 2025 and remained off dialysis for nine months while awaiting a human donor organ. The organ, from a Yucatan miniature pig, had been altered to reduce immune rejection by removing certain sugars and adding human genes. This record duration suggests pig kidneys could serve as a bridge for patients on long transplant waiting lists.
