Ang. frysningen, från Alcors hemsida;

The current technology favored by Alcor is vitrification, not freezing. Vitrification is an ice-free process in which more than 60% of the water inside cells is replaced with protective chemicals. This completely prevents freezing during deep cooling. Instead of freezing, molecules just move slower and slower until all chemistry stops at the glass transition temperature (approximately -124°C). Unlike freezing, there is no ice formation or ice damage in vitrified tissue. Blood vessels have been reversibly vitrified, and whole kidneys have been recovered and successfully transplanted after cooling to -45°C while protected with vitrification chemicals.
