Ependymal cells are specialized glial cells that line the ventricles and central canal of the spinal cord in the central nervous system (CNS).
These cells form a barrier between the brain and the cerebrospinal fluid (CSF), which circulates in the ventricles and around the brain and spinal cord.
Ependymal cells have a ciliated surface that facilitates the movement of CSF through the ventricles and the central canal of the spinal cord.
They also have stem cell-like properties and can differentiate into other cell types in response to injury or disease in the CNS.
Ependymoma is a type of brain tumor that arises from the ependymal cells.
These tumors are typically slow-growing and can occur in both adults and children.
Ependymomas can cause symptoms such as headaches, nausea, and vomiting, and treatment typically involves surgery, radiation therapy, and chemotherapy.
