Beta cell heterogeneity markers. Schematic indicating the primary molecules that were used to separate islet beta cell subpopulations. Each factor is categorized based on its surface localization or function. The distinct beta cell subpopulations are schematized as different colored dots and the main phenotypic characteristics or functions associated with these beta cell subpopulations are indicated. This schematic summarizes the concepts and respective references that were discussed in the text.
