Supercooling enables long-term transplantation survival following 4 days of liver preservation.

The realization of long-term human organ preservation will have groundbreaking effects on the current practice of transplantation. Herein we present a new technique based on subzero nonfreezing preservation and extracorporeal machine perfusion that allows transplantation of rat livers preserved for up to four days, thereby tripling the viable preservation duration.
