GN has been found not only in serotonin-producing enterochromaffin (EC) cells (Cetin et al. 1994; Hill et al. 1995) and in somatostatin-producing (D) cells (Ieda et al. 1998) but also in goblet cells and/or colonocytes (Cohen et al. 1995, 1998; Date et al. 1996; Lewis et al. 1993; Li and Goy 1993; Li et al. 1995) and in Paneth cells of the small intestine (Cohen et al. 1998; Date et al. 1996; de Sauvage et al. 1992). Here, SST is linked to ganglioneuroma.
