Ependymoglial cells are a type of neuroglial cell found in the central nervous system (CNS), including the brain and spinal cord. These cells play important roles in supporting and protecting neurons, the electrically excitable cells that transmit information in the form of electrochemical signals.

There are two main types of ependymoglial cells: ependymal cells and radial glia.

1. Ependymal cells line the ventricular system of the brain and the central canal of the spinal cord, where they help to create a smooth surface that allows cerebrospinal fluid (CSF) to flow freely. These cells have hair-like projections called cilia that beat in a coordinated manner to help move CSF through the ventricular system.
2. Radial glia are a type of ependymoglial cell that is particularly important during brain development. They provide structural support for developing neurons and help to guide them to their correct locations within the CNS. Additionally, radial glia can differentiate into other types of cells in the CNS, including both neurons and glial cells.

It's worth noting that ependymoglial cells have been found to play a role in the development of certain types of brain tumors, such as ependymomas and glioblastomas. However, more research is needed to fully understand the relationship between these cells and cancer.
