This research investigates the use of an insulinotropic factor, glucagon-like peptide-1 (GLP-1), to enhance insulin secretion from islets within a macrocapsule. A zinc-crystallized form of GLP-1 was added to the macrocapsule device to have a longer and more controlled release of the bioactive monomer GLP-1. The type of macrocapsule device used for this study consisted of a hollow fiber (MWCO 100,000 and 1 mm inner diameter) containing rat islets and GLP-1 crystals within a poly(N-isopropylacrylamide-co-acrylic acid) (2 mol% acrylic acid) matrix. When incubating the system in media with a high glucose concentration (300 mg/dL), insulin secretion was enhanced with a >85% increase after an induction period. When the same type of system was used in a dynamic perfusion experiment, similar results were obtained. GLP-1 crystals can be an effective form to be entrapped in a bioartificial pancreas to enhance insulin secretion function, especially at high glucose concentrations.
