Ribosomes happen to be basophilic.]. Chief cells of the stomach secrete the digestive enzymes (pepsins) of the stomach and have the typical appearance of serous-secretory epithelial cells. Secretory vesicles (containing pepsinogen) are clearly visible in the apical cytoplasm of chief cells.
Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells ) are one of the two cell types of the parathyroid glands, along with oxyphil cells . The chief cells are much more prevalent in the parathyroid gland than the oxyphil cells. It is perceived that oxyphil cells may be derived from chief cells at puberty, as they are not present at birth like chief cells. Chief cells appear as a dark purple in an H&E stain, with the oxyphil cells staining as a lighter pink. They are polygonal in shape with a round nucleus. The chief cells play a large role in the endocrine system, as they secrete parathyroid hormone (PTH), which is involved in calcium homeostasis.
