|An astrocytic cell from rat brain grown in tissue culture. It is stained with antibodies. The blue material shows stained DNA, and shows the nuclei of the astrocyte and other cells.|
Astrocytes do many things. They help the endothelial cells of the blood–brain barrier, provide nutrients to the nervous tissue, keep extracellular ions in balance. They also help repair the brain and spinal cord after traumatic injuries.
