A milestone in cryobiology announced this week is literally heart-warming.
A new nanoparticle technology warmed cryopreserved heart valves and blood vessels without damaging the tissues, found a study published Wednesday in the journal Science Translational Medicine. According to the researchers, this means that cryopreserving human hearts and kidneys in organ banks — and making them available for later use in patients — is finally within sight.
“We are not in any way declaring victory here,” said John Bischof, senior author of the study and a mechanical engineering professor at the University of Minnesota. “We have promising results, but we have not yet done it,” he said, warning of “many hurdles” still ahead.Share
