How are Astrocytes Identified in Histological Sections?
Astrocytes are identified using specific staining techniques and markers:
1. Histological Stains: Hematoxylin and eosin (H&E) staining can visualize astrocytes, but more specific methods are often required. 2. Immunohistochemistry: Astrocytes are commonly identified using glial fibrillary acidic protein (GFAP) antibodies, which bind to intermediate filaments within the cells. 3. Electron Microscopy: This technique provides detailed images of astrocytic processes and their interactions with other cell types.
