WebHistology Learning System [ Endocrine System, pituitary gland, posterior, pituicytes] WebPituicytes are main type of astroglia in the neurohypophysis (Hatton, 1988 ). Pituicytes express astroglial markers GFAP and S100B; these cells are morphologicaly heterogeneous being sub-classified into major, dark, ependymal, oncocytic and granular pituicytes ( Takey and Pearl, 1984 ).
WebIn histological terms, what are the three types of cell found in the adenohypophysis? A Chromophils Chromophobes Folliculostellate 7 Q What histological process allows for the differentiation of different hormone-secreting cells in the adenohypophysis? A Immunohistochemistry (antibodies to specific hormone or receptor) 8 Q WebUnmyelinated axons from neurons in the supraoptic and paraventricular hypothalamic nuclei travel into the pars nervosa via the infundibulum and end as Herring bodies. Also present among the axons and terminals are pituicytes, highly branched cells that resemble astrocytes. 1000x Main Slide Unmyelinated axons Herring bodies Pituicytes Capillaries
Pituicytes are similar to astrocytes, another type of glial cell. Their main role is to assist in the storage and release of hormones of the posterior pituitary. Pituicytes surround axonal endings and regulate hormone secretion by releasing their processes from these endings. See more Pituicytes are glial cells of the posterior pituitary. Their main role is to assist in the storage and release of neurohypophysial hormones. See more Pituicytomas are rare tumors that arise from pituicytes. They may be mistaken for the much more common pituitary adenoma, as well as See more Pituicytes are located in the pars nervosa of the posterior pituitary and interspersed with unmyelinated axons and Herring bodies. They generally stain dark purple with an H&E stain and are among the easiest structures to identify in the region.
