Isolated pancreatic islet yield and quality is inversely related to organ donor age in rats.

ABSTRACT: Pancreatic islets consist of several endocrine cell types that maintain glucose homeostasis. Type 1 diabetes (T1D) results from autoimmune-mediated destruction of insulin producing beta cells in pancreatic islets. Islet transplantation is a treatment for certain individuals with T1D. Islet transplantation in rodents, as an experimental model of the clinical scenario, requires consistency of islet quantity and quality to obtain reproducible results. In this study, we investigated the yield and function of the isolated islets from rats of different ages. Pancreata were harvested from young (10-20 week-old), intermediate (21-40 week-old) and old (>41 week-old) male rats and islets were isolated using a standard protocol. Islet number, morphometry, viability, function, and metabolism were char
