Chromophobe cell
Chromophobe Cell
Chromophobe cells (pronounced: kroh-muh-fohb sel) are a type of cell found in the anterior pituitary gland. The term "chromophobe" is derived from the Greek words "chroma" meaning color and "phobos" meaning fear, indicating these cells' characteristic lack of staining affinity.
Etymology
The term "chromophobe" comes from the Greek words "chroma" (χρώμα), meaning "color", and "phobos" (φόβος), meaning "fear". This name was given due to the cells' lack of affinity for standard histological stains, a property which makes them appear relatively colorless compared to the more intensely stained acidophilic cells and basophilic cells of the pituitary gland.
Function
Chromophobe cells are thought to be functionally inactive, but some may represent stem cells or be cells that have degranulated. They are larger than other pituitary cells and have a pale cytoplasm due to the presence of few secretory granules.
