Immunocytochemical evidence for the presence of somatostatin-like immunoreactivity in scattered cells of the duct system of the submandibular glands in the Monkey,Macaca irus

Summary Using the indirect immunofluorescent technique with anti-somatostatin serum, the distribution of scattered cells in the duct system of submandibular glands in the Monkey, Macaca irus has been assessed. In both males and females, these cells are located only in some portions of the duct system, e.g. striated ducts and excretory ducts. No immunoreactive cells were observed in the intercalated ducts or in secretory endpieces. The lymphatic node constantly adjacent to the submandibular gland did not contain immunoreactive cells. In the parotid glands, no immunoreactive cells to antisomatostatin immuneserum were ever observed
