Figure 2.
Immunohistochemical staining of the pancreatic tissues with antibodies against various cell markers: (a) chromogranin and (b) synaptophysin are neuroendocrine cell markers, while (c) insulin is more specific for insulin-secreting β-cells within islets and (d) cytokeratin labels epithelial cells. The majority of residual pancreatic tissues demonstrate staining compatible with endocrine islet cells rather than exocrine pancreatic tissues (magnification for all images × 40)
