Abstract
The human endocrine cells reacting with the monoclonal antibody HISL-19 were identified with hormone antisera of proven specificity using a double immunostaining procedure. The epitope for HISL-19 was found in all types of pituitary cells except ACTH cells, in thyroid C cells, in all types of adrenal medullary and pancreatic islet cells and in somatostatin and pancreatic polypeptide cells of the gastrointestinal mucosa. No staining was found in parathyroid cells and in most gastrointestinal endocrine cells. Either paranuclear focal accumulation or diffuse cytoplasmic distribution of immunoreactive material were found. The spectrum of HISL-19 immunoreactive cells was found to be only in part complementary to that of cells immunoreactive for chromogranin A. Thus, it is concluded that the monoclonal antibody HISL-19 is a useful addition to other immunohistochemical markers for the detection of cells showing neuroendocrine features.
