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.

Identify basophils, acidophils and chromophobes and verify that the relative frequencies of the cells are different in different parts of the adenohypophysis.
