Anatomical terminology

In the parathyroid gland, the parathyroid oxyphil cell is larger and paler than the parathyroid chief cell.[1]

These cells can be found in clusters in the center of the section and at the periphery.[2][3][4][5] Oxyphil cells appear at the onset of puberty, but have no known function. With nuclear medicine scans, they selectively take up the Technetium-sestamibi complex radiotracer dye to allow delineation of glandular anatomy.[6] Oxyphil cells have been shown to express parathyroid-relevant genes found in the chief cells and have the potential to produce additional autocrine/paracrine factors, such as Parathyroid hormone-related protein (PTHrP) and calcitriol.[7] More work needs to be done to fully understand the functions of these cells and their secretions.
