Ependymal cells

Ependymal cells are ciliated epithelial-like glial cells that line the ventricles of the brain and the central canal of the spinal cord. Their coordinated ciliary beating helps circulate cerebrospinal fluid (CSF). They contribute to the blood-CSF barrier, secrete factors into the CSF, and in certain niches (like the lateral ventricles), some can act as neural stem cells (radial glia-like cells).
