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.
