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.
Mayo Clinic is a nonprofit hospital system with campuses in Rochester, Minnesota; Scottsdale and Phoenix, Arizona; and Jacksonville, Florida. [22] [23] Mayo Clinic employs 76,000 people, including more than 7,300 physicians and clinical residents and over 66,000 allied health staff, as of 2022. [5]

The new Fairview Red Wing Medical Center served the clinic and hospital needs of Red Wing and the surrounding area. Red Wing Medical Center opened in 2001 on the West side of Red Wing, Minnesota located on Fairview Boulevard, just off Red Wing Avenue S near US Highway 61. Red Wing Medical Center was purchased by Mayo Clinic in 2012 and was ...
The net effect is a calcium wave that propagates from cell to cell. Extracellular release of ATP and consequent activation of purinergic receptors on other astrocytes may also mediate calcium waves in some cases. In general, there are two types of astrocytes, protoplasmic and fibrous, similar in function but distinct in morphology and distribution.
The two types of aquaporins expressed in the CNS are aquaporin-1, which is expressed by specialized epithelial cells of the choroid plexus, and aquaporin-4 (AQP4), which is expressed by astrocytes. [12] [13] Aquaporin-4 expression in astrocytes is highly polarized to the endfoot processes ensheathing the cerebral vasculature. Up to 50% of the ...
The main role of astrocytes is to maintain brain homeostasis and neuronal metabolism. When the astrocytes become activated, they begin to respond to damage. [3] Astrocyte activation, known as astrogliosis, responds to neurological trauma, infections, degradations, epilepsy, and tumorigenesis. Each neurological insult plays a major role in ...
Glial fibrillary acidic protein (GFAP) is a protein that is encoded by the GFAP gene in humans. [5] It is a type III intermediate filament (IF) protein that is expressed by numerous cell types of the central nervous system (CNS), including astrocytes [6] and ependymal cells during development. [7]
