Organ cryopreservation

Organ cryopreservation is the cryopreservation of animals or human organs, typically around -196 °C using liquid nitrogen. At this temperature, organs can be preserved for a long period, often more than a decade.
, organ cryopreservation remains experimental. Most organs are usually preserved at a temperature of just above 0°C, which allows them to be stored for a few hours to a few days. Certain organs may be preserved at temperatures between -20°C to -50°C, enabling storage for a few weeks to a few months. In 2023, researchers successfully cryopreserved rat kidneys at -196°C using liquid nitrogen for 100 days.
