Secretory granules
This electron micrograph illustrates secretory granules in the endocrine cells composing the islets of Langerhans of the pancreas. These electron-dense granules are distributed throughout the cytoplasm, indicating the lack of polarity, a characteristic of endocrine cells. Endocrine pancreas (islets of Langerhans) 12,000x
