Microglia are the cells in the CNS that can do this in normal, healthy tissue, and they are therefore also referred to as CNS-resident macrophages. The ependymal cell is a glial cell that filters blood to make cerebrospinal fluid (CSF), the fluid that circulates through the CNS. Because of the privileged blood supply inherent in the BBB, the extracellular space in nervous tissue does not easily exchange components with the blood.
Ependymomas arise from the ependymal cells that line the ventricles of the brain and the center of the spinal cord. These tumors are divided into four major types: Subependymomas (grade I): Typically slow-growing tumors. Myxopapillary ependymomas (grade I): Typically slow-growing tumors.
