Immunohistochemical localization of glial fibrillary acidic protein (GFAP) in rat pineal stalk astrocytes.
Year: 1992
Type: article
Abstract: In the present work, the presence and distribution of astrocytes in the rat pineal stalk is investigated applying an immunohistochemical technique for the demonstration of glial fibrillary acidic protein (GFAP) on Epon-embedded semithin sections (0.5 micron thick). GFAP-immunoreactive cells are evenly and regularly distributed along the entire pineal stalk. The GFAP-immunoreactive cells display a stellate shape showing variable numbers of cell processes that are mainly oriented parallel to the longitudinal stalk axis. Astrocytic processes show a clear tendency to encircle the remaining elements of the pineal stalk; i.e., pinealocytes, nerve fibres and blood vessels. Furthermore, glial processes form a cover layer separating the stalk from surrounding anatomical structures.
