Research Article: The Beta Cell in Its Cluster: Stochastic Graphs of Beta Cell Connectivity in the Islets of Langerhans

Date Published: August 12, 2015 Publisher: Public Library of Science Author(s): Deborah A. Striegel, Manami Hara, Vipul Periwal, Morten Gram Pedersen Abstract: Pancreatic islets of Langerhans consist of endocrine cells, primarily α, β and δ cells, which secrete glucagon, insulin, and somatostatin, respectively, to regulate plasma glucose. β cells form irregular locally connected clusters within … Continue reading
