Witryna19 maj 2024 · Human Islet Microtissue Perifusion in Organ-on-a-Chip Platform Provides Diabetes Researchers a Powerful Tool for Studying Insulin Release Dynamics New study confirms hanging drop... WitrynaThe capacity of ECs, with or without MSCs, to adhere to and grow into human islets was analyzed. The survival and functionality of these composite islets were evaluated in a dynamic perifusion assay, and their capacity for angiogenesis in vitro was assessed in a three-dimensional fibrin gel assay.

WitrynaAims/hypothesis: Some work was reported on Syn-4's role in biphasic glucose-stimulated insulin secretion (GSIS), but its precise role in insulin SG exocytosis remains unclear. In this paper we examine this role in human beta cells. Methods: Biphasic GSIS was determined by islet perifusion assay. Witryna10 lis 2024 · Conventionally, static glucose-stimulated insulin secretion (GSIS) assay is used to determine human islet functionality. Macro islet perifusion apparatus has also been recently applied to study insulin secretion kinetics of isolated human islets due to its advantages compared to GSIS, which can measure dynamic hormone secretion.
