The pyloric glands of a reptile, the ruin lizard (Podarcis sicula camp
estris De Betta), have been examined by immunocytochemistry and by tra
nsmission electron microscopy. There are four main ultrastructural typ
es of enteroendocrine cells whose secretory granules showed similariti
es to mammalian EC cells (type I), D1 or ECL cells (type II), G cells
(type III), and D cells (type IV). Immunogold staining identified and
characterized the type IV cells as the somatostatin-storing cells. The
y were of the open type, with round or ovoid immunoreactive granules o
f varying electron density. (C) 1996 Academic Press, Inc.
