Pituitary Histology - Adenohypophysis

Basophil cells

Based on their hormone products basophils are divided into three subtypes (PAS stain all types reddish).

Thyrotrophs - produce thyroid stimulating hormone (TSH or thyrotropin).
Gonadotrophs - produce follicle stimulating hormone (FSH) and luteinizing hormone (LH)
- FSH stimulates in the male seminiferous tubule and female early follicular growth.
- LH stimulates male Leydig cell testosterone production and female oestrogen (estrogen) production, late follicular maturation, formation of corpus luteum.
Corticotrophs - (or adrenocorticolipotrophs) produce adrenocorticotropic hormone (ACTH or corticotropin) and lipotropin (LPH).
- cell type in the pars intermedia where ACTH and LPH precursor undergoes hydrolysis into melanocyte stimulating hormone (MSH) and other peptides.

Chromophobe cells

cells are unstained or weakly stained cells.
either acidophils or basophils in a dormant or recently degranulated stage.
may also include the secretory stem cells.

Acidophil cells

about 65% of all cells.
rounded and smaller than basophil cells (other stains identify subtypes).
Somatotrophs - produce growth hormone (GH or somatotropin), stimulates liver cells to produce polypeptide growth factors which stimulate growth (stain with orange G)
Mammotrophs - (lactotrophs) produce prolactin, maternal numbers increase in third trimester and postnatally in early lactation.

Pituitary, sheep - (Stain - Haematoxylin Eosin) Acidophils are dark pink and basophils look light pink/blue.
