Composite light micrograph of a pancreatic islet with different fluorescent stains to show the relative content and distribution of the cells that secrete the major peptide hormones of the islet: insulin (beta or B cells, coloured blue), glucagon (alpha or A cells, coloured green), and somatostatin (delta or D cells, coloured red). One will note that there are a few fluorescent cells, outside the islet, that stain one of the three colours. These are either isolated islet cells that 1) are not confined to the islet, 2) belong to an islet almost entirely outside the plane of the section, or 3) are an artefact of sectioning, which was done on frozen tissue.
