Evaluation of a high-yield technique for pancreatic islet isolation from deceased canine donors
… We hypothesized that clinically acceptable islet yield and purity could be achieved by using deceased canine donors and standard centrifugation equipment. Pancreata were procured from dogs euthanized for reasons unrelated to this study. Initial anatomic studies were performed to evaluate efficacy …
