Transplant organs can be supercooled to below zero for longer storage

September 17, 2019

The length of time that a liver can be kept outside the body has been extended to a day and a half by a new “supercooling” method, which for the first time has let human organs be safely stored at sub-zero temperatures. The technique, which lowers the organ’s temperature below zero without forming damaging ice crystals, could boost the number of liver transplants carried out and could also be used on other organs, says Reinier de Vries of Harvard Medical School in Boston.
