New pretreatment method boosts islet transplant survival in diabetes

A pretreatment step could help transplanted pancreatic islets survive longer in patients with type 1 diabetes, according to a new preclinical study from Weill Cornell Medicine investigators. One combination of small molecules extended the cells' lives in female mice, and adding two molecules to the mixture boosted cell survival in male mice.
