Ependymal Cells [edit]. The ependyma is made up of ependymal cells, ependymocytes, a type of glial cell. These cells line the CSF-filled ventricles in the brain and the central canal of the spinal cord. The cells are ciliated simple columnar epithelium-like cells.pendyma is the thin epithelium-like lining of the ventricular system of the brain and the central canal of the spinal cord.
Brain tumors are classified according to histology, but tumor location and extent of spread are important factors that affect treatment and prognosis. Ependymomas arise from ependymal cells that line the ventricles and passageways in the brain and the center of the spinal cord. Ependymal cells produce cerebrospinal fluid (CSF). These tumors are classified as supratentorial or infratentorial. In children, most ependymomas are infratentorial tumors that arise in or around the fourth ventricle. According to the 2016 revision to the World Health Organization (WHO) classification of tumors of the central nervous system, ependymal tumors are classified into the following five main subtypes:
