Results of subtotal parathyroidectomy for primary chief cell
(7,18) Immunohistochemically, the chief cells
are positive for neuroendocrine markers, tyrosine hydroxylase, and GATA3, whilst the surrounding sustentacular cells express S100 and GFAP (glial fibrillary acidic protein).
: The chief cells
can be recognized at the 13th week of development (42).
The chief cells
also appear normal and occupy about a quadrant of the gastric mucosa.
never showed positivity for VacA, and intracellular VacA was rarely detected in epithelial cells.
In stomach tissue, no marked damage but intensive blue staining was observed, indicating migration of gastric chief cells
to the outer layer of the stomach lining, in only control and metoclopramide groups but not in the RVX-treated groups (Figure 3(a)).
The glandular part had the gastric glands, which could be divided to two layers in the HE stain: the luminal layer stained red as the acidophilic parietal cells were predominant, and the basal layer stained blue as the basophilic chief cells
with basal nuclei and clear cytoplasm but indefinite cellular outlines are observed.
The patient underwent right lower parathyroidectomy and its histopathology report showed abundant clear cells and chief cells
in a disarray with increased nucleus to cytoplasmic ratio, neutrophilic infiltrate and a rim of compressed normal parathyroid parenchyma with intact capsule.
Recently, the applicant identified Troy+ chief cells
as a novel stem cell population in the corpus epithelium.
