title: The distribution of endocrine cells along the mouse small intestine. Bombesin and somatostatin producing cells.
abstract: The topographical distribution and incidence of endocrine cells in the crypt and villus epithelium and along the length of the mouse intestine was studied. Cells containing somatostatin and bombesin like reactivity were stained by immunocytochemical techniques using polyclonal antiserum. Most of the somatostatin cells were found in the duodenum, jejunum and ileum, and these cells were generally more frequent on the villus compared to the crypts. This may indicate that the somatostatin cells develop late in the endocrine cell lineage. Bombesin like cells were rare in occurrence, and were only present in measureable numbers in the ileum, where they were observed in the crypt and villi. The application of ELISA assays to determine the specificity of the antisera for these peptides is also discussed.
