Nettet25. jul. 2024 · Insulin is a peptide hormone composed of 51 amino acids that is synthesized, packaged, and secreted in pancreatic beta cells. The mechanisms of insulin secretion and measurements of beta cell function in normal subjects and patients with various diseases will be reviewed here. The mechanisms of insulin action are … NettetFigure 3. hiPS cell-derived beta cells synthesize insulin. Staining for C-peptide and insulin was performed by immunofluorescence on Cellartis beta cells at Day 14 post-thawing. Colocalization of insulin and C-peptide indicates intracellular insulin synthesis. Scale bar = 100 μm.
