Heart tissue cryogenics breakthrough gives hope for transplant patients

Successful freezing and rewarming of tissue sections by US team avoids damage by infusing the them with magnetic nanoparticles, paving way for entire organs

Scientists have succeeded in cryogenically freezing and rewarming sections of heart tissue for the first time, in an advance that could pave the way for organs to be stored for months or years.

If the technique scales up to work for entire organs - and scientists predict it will - it could save the lives of thousands who die each year waiting for transplants.
