Early monociliated ependymal cells are differentiated to multiciliated ependymal cells for their function in circulating cerebrospinal fluid. [3] The basal membranes of these cells are characterized by tentacle-like extensions that attach to astrocytes. The apical side is covered in cilia and microvilli. [4]
Other cellular extensions that protrude from the cell membrane are known as membrane protrusions or cell protrusions, also cell appendages, such as flagella, and microvilli. [ 8 ] [ 9 ] Microtentacles are cell protrusions attached to free-floating cells, associated with the spread of some cancer cells .
Tanycytes are highly specialized ependymal cells found in the third ventricle of the brain, and on the floor of the fourth ventricle. Each tanycyte has a long basal process that extends deep into the hypothalamus. It is possible that their function is to transfer chemical signals from the cerebrospinal fluid to the central nervous system.
The subependymal zone (SEZ) is a cell layer below the ependyma in the lateral ventricles of the brain. It is an adult version of the embryonic forebrain germinal zone.This region contains adult neural stem cells also called neuroepithelial cells which have the potential to generate new neurons and glial cells. [1]
The central canal (also known as spinal foramen or ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. [1] The central canal lies below and is connected to the ventricular system of the brain , from which it receives cerebrospinal fluid, and shares the same ependymal lining.
The tela choroidea (or tela chorioidea) is a region of meningeal pia mater that adheres to the underlying ependyma, and gives rise to the choroid plexus in each of the brain’s four ventricles.
Related to its secretory function, the SCO is partially composed of ependymal cells. [1] [30] These ependymocytes are characterized by elongated cell bodies that contain secretory materials and are covered in cilia. [1] [30] The most prominent of these is the glycoprotein SCO-spondin. [31]
Illustration of the four different types of glial cells found in the central nervous system: ependymal cells, astrocytes, microglial cells, and oligodendrocytes. Lesions in MS are heterogeneous and there are four different patterns in which they start, probably due to different underlying pathogenesis. Nevertheless, it seems than the last stage ...
