Endocrine pancreatic tumors: ultrastructure
M Kostianovsky
Endocrine pancreatic tumors are frequently multicellular and produce several hormones and peptides. A review of the basic concepts of hormone secretion, pancreatic islet cell composition and ultrastructural make-up of tumors is presented. The importance of correlating ultrastructural, immunocytochemical and biochemical studies of these tumors is emphasized.
