Video: Vitrification of human tissue

By Lisa McDonald / July 22, 2020

Vitrification is the process through which a material turns into a glass or glasslike substance by undergoing rapid cooling. Though the discovery this year that a man’s brain vitrified during the Mount Vesuvius eruption surprised some people, vitrification of human tissue is actually a well-established practice in fertility treatment.
