Using indirect immuno-
peroxidase staining technique,
localization of immunoreactive
follicle-stimulating hormone (IR-FSH) is demonstrated in the
cytoplasm of the
epithelial cells of normal
human stomach. In view of their triangular shape and
central nucleus and their predominance in the intermediate glands of the
gastric mucosa, these
cells are identified as parietal
cells. The stromal
tissue is devoid of
staining reaction.
