A chromophobe is a histological structure that does not stain readily, and thus appears relatively pale under the microscope.. Chromophobe cells are one of three cell stain types present in the anterior and intermediate lobes of the pituitary gland, the others being basophils and acidophils.
The anterior pituitary (also called the adenohypophysis or pars anterior) is a major organ of the endocrine system.The anterior pituitary is the glandular, anterior lobe that together with the (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.
Rathke's pouch is a sac-like structure that gives rise to the pars distalis, pars intermedia, and pars tuberalis of the pituitary gland. The cells of Rathke's pouch proliferate and differentiate into various hormone-producing cells, including Somatotrophs, Lactotrophs, Corticotrophs, Thyrotrophs, and Gonadotrophs.
In the anterior pituitary, the term "acidophil" is used to describe two different types of cells which stain well with acidic dyes.. somatotrophs, which secrete growth hormone (a peptide hormone)
A few sources include the pars intermedia as part of the posterior lobe, but this is a minority view. It is based upon the gross anatomical separation of the posterior and anterior pituitary along the cystic remnants of Rathke's pouch, causing the pars intermedia to remain attached to the neurohypophysis.
The pars intermedia is one of the three parts of the anterior pituitary. It is a section of tissue sometimes called a middle or intermediate lobe, between the pars distalis, and the posterior pituitary. [1] It is a small region that is largely without blood supply. [2] The cells in the pars intermedia are large and pale.

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.
