However, these cells did not self-renew and were subsequently depleted as they generated new neurons, thus failing to satisfy the requirement for stem cells. [6] [7] One study observed that ependymal cells from the lining of the lateral ventricle might be a source for cells which can be transplanted into the cochlea to reverse hearing loss. [8]
Osteocytes, the most common cell type within mature cortical bone, actively participate in the growth and maintenance of TCVs through the transfer of mitochondria to endothelial cells. Scanning electron microscopy images have revealed that osteocytes possess numerous dendritic processes with expanded, endfoot-like structures. These endfeet ...
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.
As the cells grow, the neurite tangle remains centrally located and the cell bodies are squeezed to the periphery, thus explaining the rosette pattern. Depending upon their location, ependymal cells may display 2 cell poles. A luminal pole projects to the ependymal lining of a ventricle and a "submesenchymal pole" projects toward the surface of ...
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.

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.
Progenitor ependymal cells are monociliated but they differentiate into multiciliated ependymal cells. [6] [7] Unlike the ependyma, the choroid plexus epithelial layer has tight junctions [8] between the cells on the side facing the ventricle (apical surface). These tight junctions prevent the majority of substances from crossing the cell layer ...
Each cell in the respiratory epithelium has around 200 motile cilia. [12] In the reproductive tract, smooth muscle contractions help the beating of the cilia in moving the egg cell from the ovary to the uterus. [13] [15] In the ventricles of the brain ciliated ependymal cells circulate the cerebrospinal fluid.
