Poin Utama
- A 66-year-old American patient received a pig kidney with 69 genomic modifications.
- The kidney functioned for 271 days and freed the patient from dialysis; this is a record.
- After initial control of rejection signs, the organ was removed due to vascular deterioration.
- The patient subsequently received a human donor kidney transplant.
Dalam Angka
66-year-old American Tim Andrews received a genetically modified pig kidney transplant due to end-stage renal failure linked to type 2 diabetes. Following the surgery on January 25, 2025 at Massachusetts General Hospital, the kidney began functioning immediately and kept the patient off dialysis for 271 days. This duration is recorded as a milestone in clinical xenotransplantation history.
The organ was sourced from a Yucatan miniature pig that underwent 69 genomic modifications; these changes aimed to prevent recognition by the human immune system, add human genes, and deactivate viruses in the pig DNA. Mild rejection signs seen in the first months were controlled with medication adjustments, but around the sixth month the kidney's blood vessels began to deteriorate and the organ was removed.
Experts view this case as demonstrating both the promise and the ongoing challenges of xenotransplantation. With roughly 100,000 patients awaiting a kidney in the U.S. while only about 25,000 transplants are performed annually, the use of animal organs as a temporary bridge offers significant hope.

Pertanyaan Umum
- How long did the pig kidney function and why was it removed?
- The kidney worked for 271 days (about 9 months); it was surgically removed in the sixth month due to vascular deterioration and thrombosis in the blood vessels.
- How was the pig kidney prepared?
- The Yucatan miniature pig underwent 69 genomic modifications; human genes to prevent immune rejection were added and endogenous viruses were deactivated.
- What does this development mean for patients awaiting organ transplants?
- With over 100,000 people waiting for a kidney in the U.S. and only 25,000 transplants performed yearly, xenotransplantation could serve as a temporary alternative to fill this gap.
