FAQ
Clear distinctions between today's preservation limits and the long-term research goal.
The essential questions.
Why can organs not simply be frozen?
Ordinary freezing allows ice crystals to form. Those crystals can rupture membranes and disrupt the structures needed for the organ to function after warming.
What is vitrification?
Vitrification is the transition into a glass-like state without forming damaging crystalline ice. Achieving it safely and reversing it successfully are separate scientific challenges.
What are cryoprotective agents?
Cryoprotective agents, or CPAs, are molecules used to reduce ice formation during cooling. Their concentration, toxicity, distribution and removal all influence biological recovery.
Why are conventional CPAs described as a limitation?
Conventional CPAs can require concentrations that have toxic effects. That trade-off becomes more difficult at the scale of whole organs.
Is long-term organ banking available today?
No. Reversible long-term organ preservation is presented on this website as a research goal, not as a current clinical capability.
Why does the story move below −130°C?
Below the glass transition, molecular movement slows dramatically. This cryogenic storage range frames the long-term research goal at the end of the site's temperature descent.
What does “the molecule company” mean?
It describes the stated focus on cryoprotective molecules rather than preservation machinery: designing and validating the chemical layer the preservation process depends on.
