    Astrocytes stained for GFAP (green) and aquaporin-4 (purple) In a study published in 2012, [7] a group of researchers from the University of Rochester, headed by M. Nedergaard, used in-vivo two-photon imaging of small fluorescent tracers to monitor the flow of subarachnoid CSF into and through the brain parenchyma.

  3. Potassium spatial buffering - Wikipedia

    en.wikipedia.org/wiki/Potassium_spatial_buffering

    Potassium spatial buffering is a mechanism for the regulation of extracellular potassium concentration by astrocytes. Other mechanisms for astrocytic potassium clearance are carrier-operated or channel-operated potassium chloride uptake. [1] The repolarization of neurons tends to raise potassium concentration in the extracellular fluid. If a ...

    Astrocytes (green) in the context of neurons (red) in a mouse cortex cell culture 23-week-old fetal brain culture human astrocyte Astrocytes (red-yellow) among neurons (green) in the living cerebral cortex. Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells.

    AQP-4 exhibits a polarized distribution in astrocytes, with a 10-times higher concentration in astrocytic endfeet, which are in contact with blood vessels, compared to non-endfoot regions. [ 40 ] In contrast to the lateral membranes of numerous epithelial cell types , astrocyte lateral membranes are devoid of tight junctions , that prevent ...

  6. Cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid

    Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates.. CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations.

  7. Autoimmune GFAP astrocytopathy - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_GFAP_Astrocytopathy

    There are multiple disorders associated with improper GFAP regulation and glial scarring is a consequence of several neurodegenerative conditions. The scar is formed by astrocytes interacting with fibrous tissue to re-establish the glial margins around the central injury core and is partially caused by up-regulation of GFAP.

  9. Colony-stimulating factor - Wikipedia

    en.wikipedia.org/wiki/Colony-stimulating_factor

    The name "colony-stimulating factors" comes from the method by which they were discovered. Hematopoietic stem cells were cultured (see cell culture) on a so-called semisolid matrix, which prevents cells from moving around, so that, if a single cell starts proliferating, all of the cells derived from it will remain clustered around the spot in the matrix where the first cell was originally located.
