Pig kidneys frozen for a year revived for transplant
scientists successfully rewarm pig kidneys stored at -150°c for over a year, enabling potential human organ banking. this could address organ transplant challenges.
scientists have successfully rewarmed pig kidneys that were cooled to -150°c and stored in a freezer for over a year. the kidneys were treated with cryoprotectants and iron oxide nanoparticles, then transplanted into pigs, where they regained color and produced urine. this achievement could enable the banking of human organs for future transplantation, potentially addressing challenges such as organ shortages and limited preservation times. researchers, including erik finger and john bishof, hope to replicate the findings with human organs.
