Cryopreserved pancreatic islet cells (IMAGE) University of Minnesota Caption Researchers at the University of Minnesota Twin Cities and Mayo Clinic were able to store tiny droplets encapsulated with pancreatic islet cells at very low temperatures for up to nine months and then use novel rewarming techniques to bring them back to their original state before transplantation. Shown is one approach studied by the team, which uses lasers to rapidly rewarm cryopreserved droplets of islets.
