About the Company

UntilLabs

Advances reversible organ cryopreservation technology

UntilLabs develops reversible cryopreservation technology to extend the viability of human organs for transplantation. The goal is to keep organs alive at cryogenic temperatures long enough to improve organ matching and reduce waste from time limits, potentially weeks or months of preserved time. The approach uses cooling to very low temperatures (below -130°C) with cryoprotectants to prevent ice damage, followed by advanced warming methods to revive the organs without harm. While cryopreservation has worked for cells and simple tissues, UntilLabs works on scaling this to whole organs, tackling challenges like ice formation and nutrient/waste management in large tissues. In the long term, the company envisions whole-body reversible cryopreservation as a bridge to future medical cures.
