Basophil cell

An anterior pituitary basophil is a type of cell in the anterior pituitary which manufactures hormones.
It is called a basophil because it is basophilic (readily takes up bases), and typically stains a relatively deep blue or purple.
These basophils are further classified by the hormones they produce. (It is usually not possible to distinguish between these cell types using standard staining techniques.)
B-FLAT for Basophils: FSH, LH, ACTH, TSH
