The icy world of organ freezing – Science Information, August 19, 1972
If complete organs could possibly be frozen and saved … surgeons would have the ability to carry out way more transplants…. For all their efforts, although, cryobiologists (biologists who examine the results of chilly on life) haven’t been very profitable with organ freezing…. No person up to now has cooled complete mammalian hearts any decrease [than −20° Celsius] or longer [than six hours] and revived them.

Scientists nonetheless battle to maintain donor hearts on ice for longer than six hours, however it’s now doable to retailer a special organ — the liver — at below-freezing temperatures for greater than a day. The problem has been determining how one can cease ice from crystallizing and damaging cells. In 2019, scientists reported efficiently warming up a number of human livers after supercooling them for 27 hours (SN: 10/12/19 & 10/26/19, p. 10). This and different preservation strategies similar to freezing at excessive pressures or thawing utilizing nanoparticles aren’t but prepared for the working room, however they’ve the potential to maintain 1000’s of lifesaving organs from going to waste annually.
