Electron microscopic examination of the intrinsic autonomic ganglia of the rat pancreas revealed the presence of small cells, when compared to the principal ganglionic neurons, within a particular type of ganglia. The small cells were often located in clusters around fenestrated capillaries, but their most striking characteristic was the presence of catecholamine-like granules distributed throughout the cytoplasm. The possible implication of this new source of catecholamines, acting either as interneurons or as neuroendocrine cells, is discussed in the light of a local regulatory mechanism for islet secretion.
