Title: Astrocytes and capillaries in cerebrum
Description:
(A): Immunofluorescence staining of neuroglial cells with antibodies against GFAP (glial fibrillary acidic protein), an intermediate filament that is found in glia cells and NOT in ependym, mouse.
(B): Immunoperoxidase staining with DAB and antibodies against GFAP, cortex, human. The asterocytes end with their terminal perivascular feet upon a arteriole (green arrow) and upon a capillary (blue arrow) and are thus involved in the blood-brain-barrier (BBB).

(C): Golgi stain, human. A higher magnification visualizes an astrocyte enveloping a capillary (blue arrow).
(D): Immunoperoxidase staining with DAB and antibodies against GFAP, human. It shows clearly the endfeet of one astrocyte contacting
an arteriole (green arrow) and a capillary (blue arrow).

Background:
Trans-parenchymal clearance of the interstitial brain fluid is facilitated by the presence of aquaporin water channels in the endfeet of astroglial cells that embrace all cerebral vessels. (See: Glymphatics POJA-L4750)
Keywords/Mesh: nervous tissue, cerebrum, blood-brain-barrier, astrocyte, glial fibrillary acidic protein, histology, POJA collection
