||P.294 right column 3rd paragraph:"11. Enteroendocrine cell lineages: The peptide- or polypeptide-producing enteroendocrine cell lineages are scattered throughout the gut epithelium. Members of these lineages usually occur singly along the gut epithelium. In mice, they represent about 7% of all cells in the stomach body (primary source 13) and 3% in the pyloric antrum (primary source 57). In the small intestine, they are more abundant in the crypts than in the villi and generally form about 0.5% of all crypt-villus cells (primary source 31). They form about 0.4% of cells in the colon (primary source 71). The identification of enteroendocrine cells of different lineages depends on the size, shape, electron density and immunocytochemical specificity of their secretory granules (ref 72). After a long debate about the neuronal vs. epithelial origin of these cells, it has been established that they share a common stem cell with other epithelial lineages in the gut (refs 73-77). Thus, enteroendocrine cells represent several cell lineages which originate from the epithelial stem cells of the gut."
