Abstract/OtherAbstract:
Specific antisera against somatostatin-28 were prepared by absorption of somatostatin-28 antisera with sepharose 4B-somatostatin-14. Indirect immunofluorescence techniques using somatostatin-14 antisera and specific antisera against somatostatin-28 were carried out to elucidate the time of occurrence of somatostatin-28 in the fetal pancreatic islets and to ascertain whether somatostatin-28 was present in the adult pancreatic islets or not, and further to examine whether cells reacting with specific antisera against somatostatin-28 are identical to those reacting with somatostatin-14 antisera or not. Somatostatin-28 like immunoreactivity occurred in the fetal pancreatic islets at 11th week's gestation and was found in all fetal pancreatic islets examined in the present study. It was also found in the adult pancreatic islets. Furthermore, cells reacting with specific antisera against somatostatin-28 in the fetal and adult pancreatic islets were identical to those reacting with somatostatin-14 antisera. Thus, the present study elucidated the presence of somatostatin-28 like immunoreactivity in the human pancreas. However, it could not be decided whether cells reacting with somatostatin-28 antisera contain either only somatostatin-28 or both somatostatin-28 and somatostatin-14; in other words, whether somatostatin-14 is produced from somatostatin-28 or not, since somatostatin-14 antisera had a cross-reactivity to both somatostatin-14 and somatostatin-28.
