Scientists rewarm and successfully transplant pig kidneys stored for over a year

Scientists have successfully rewarmed pig kidneys that were cooled to minus 150 degrees Celsius and stored in a freezer for months, MIT Tech Review reported. After rewarming, machine testing, and transplantation into live pigs, the organs regained their normal color and produced urine. [1]

According to MIT Tech Review, the pig kidneys, which are similar in size to human organs, were maintained in a glass-like preserved state for over a year in one instance. The production of urine and restored color serve as primary indicators that the organ function was recovered. [1]

Researchers express hope that they can replicate these experimental findings using human organs in the future. If successful, the long-term banking technique could enable human organs to be stored safely for upcoming transplantation procedures. [1]
