- The 14-year-old wanted her body to be frozen in case her cancer could be cured in the future
- The Cryonics Institute in Michigan says it received the body of a girl from London
London (CNN)A British teenager who died of cancer has been cryogenically frozen in the United States after winning a court case before her death.

How does the process of cryogenic freezing work?
• The person's body is cooled using an ice bath as soon as possible after he or she is declared legally dead in order to prevent decay to the brain cells and other tissues.
• The blood is flushed out and replaced with a cryoprotectant solution, or special non-toxic anti-freeze, to prevent ice crystals forming which would damage the cells.
• The body is packed in dry ice for transportation to the place where the final cooling process and storage will take place.
• The body is then slowly cooled down to even lower temperatures over several days using liquid nitrogen. Here, physical decay essentially stops.
• The body is placed in a storage tank filled with liquid nitrogen.
• Keeping a body at such low temperatures is thought to keep cells, tissues and organs intact.
• Only a handful of companies in the United States and Russia currently offer cryopreservation.
• Proponents of the process say that future advances in science will allow the subjects of cryogenic freezing to be reanimated.
• It's thought reanimation will enable any damage to cells to be repaired and fatal diseases to be cured.
• But skeptics say that there is no objective evidence yet that a human body will survive cryopreservation with cells that will work again after warming.
