New method of pancreatic islet cryopreservation marks breakt
Engineering and medical researchers have developed a new process for successfully storing specialized pancreatic islet cells at very low temperatures and rewarming them, enabling the potential for on-demand islet transplantation. The breakthrough discovery in cryopreservation is a major step forward in a cure for diabetes.

This new cryopreservation method demonstrated high cell survival rates and functionality, even after nine months of storage. Storage with this potential cryopreservation approach is theoretically indefinite.

In mice, the transplantation of these cryopreserved islet cells cured diabetes in 92% of recipients within 24 to 48 hours after transplant. These results suggest that this new cryopreservation protocol may be a powerful means of improving the islet supply chain, allowing pooling of islets from multiple pancreases and thereby improving transplantation outcomes that can cure diabetes.
