Summary Secretin has been localized by the immunogold technique in endocrine cells of the dog duodenum — previously described as “K cells” — characterized by secretory granules with double structure consisting of a secretin-containing osmiophilic core surrounded by an argyrophil halo. Granules resembling those of dog secretin cells were also found in some ultrastructurally characterized S cells of the cat, pig, rat and rabbit duodenum, thus confirming in these species the identification of S cells with secretin cells. Conversely, the cells previously described as “S cells” in the dog lacked secretin immunoreactivity.
