Oxyphil cells are a type of cell found in the parathyroid gland of some species, including humans. They have a distinctive appearance, function, and expression of parathyroid-related genes.
The second cell type in the parathyroid glands of certain animal species and humans is the oxyphil cell (Figure 58.50). These cells are absent in parathyroids of the rat, chicken, and many species of lower animals.
8 lut 2024 · There are two types of cells within the parathyroid gland, the chief cells and the oxyphil cells. Chief cells – The role of this cell type is to secrete parathyroid hormone. They contain prominent golgi apparatus and endoplasmic reticulum to allow for the synthesis and secretion of PTH.
Oxyphil cells are easily identified by their large size and eosinophilic staining compared with the chief cells. The eosinophilic staining is due to the large number of mitochondria in the oxyphil cells.
17 lip 2023 · Oxyphil Cells. Also known as oxyntic cells, these cells have no recognized endocrine function. The proportion of oxyphil cells in the parathyroid glands increases with age.
1 maj 2023 · The parathyroid glands are primarily composed of chief cells and adipocytes, with clusters of oxyphil cells scattered throughout. On H&E stain, under high power magnification, chief cells appear to have poorly demarcated borders, scant light pink cytoplasm, and large, round nuclei.
8 sie 2023 · The parathyroid glands have two distinct types of cells: the chief cells and the oxyphil cells. Chief cells: The chief cells manage the secretion of parathyroid hormone (PTH). When the cells are viewed, they contain prominent Golgi apparati and a developed endoplasmic reticulum to help with the synthesis and secretion of the hormone.
