Histology

Prinicipal cells of the pars tuberalis are low columnar in form, with the cytoplasm containing numerous lipid droplets, glycogen granules, and occasional colloid droplets. A sparse population of functional gonadotrophs are present(indicated by immunoreactivity for ACTH, FSH, and LH)^[1].
