One Pig Kidney Frozen a Year at -150°C Springs Back to Life in Transplant Tests
The breakthrough could extend organ preservation far beyond the current 24 to 36 hours, researchers said, but the kidneys still need long-term testing.

Scientists Just Revived Pig Kidneys Frozen for a Year. It Could Rewrite the Future of Organ Transplants
Researchers at the University of Minnesota managed to freeze test pig kidneys down to -238 degrees Fahrenheit (-150 degrees Celsius) with minimal damage to their vital functions.
One Pig Kidney Frozen a Year at -150°C Springs Back to Life in Transplant Tests
Researchers revived pig kidneys stored at -150°C using vitrification and nanoparticle warming, one of them for over a year. The organs produced urine after perfusion and transplant, showing function despite some chemical damage. This advances organ banking efforts amid ongoing transplant shortages.
For now, everything is at a very early stage and more tests must be done. In addition, the organ presented some injuries.

Bioethics.comPig kidneys that were “frozen” for a year have been brought back to life
Pig kidneys that were cooled to -150 °C and stored in a freezer for months have been successfully rewarmed and shown to work again for the first time, say scientists. They hope to replicate the findings with human organs. The kidneys—which are similar in size to human ones—were left in a glass-like state, in one…
Pig kidneys vitrified at -150 °C for more than a year again produce urine after reheating, a key step to create organ banks. The entry Frozen pig kidneys at -150 °C return to work: milestone in organ cryopreservation aparece primero en Merca2.
