Quantifying cilia beat frequency using high‐speed video microscopy: Assessing frame rate requirements when imaging different ciliated tissues

Physiological Reports, 2022
Motile cilia are found in numerous locations throughout our body and play a critical role in various physiological processes. The most commonly used method to assess cilia motility is to quantify cilia beat frequency (CBF) via video microscopy.

The Ependymal Region Prevents Glioblastoma From Penetrating Into the Ventricle via a Nonmechanical Force

Frontiers in Neuroanatomy, 2021
BackgroundIntraventricular penetration is rare in glioblastoma (GBM). Whether the ependymal region including the ependyma and subventricular zone (SVZ) can prevent GBM invasion remains unclear.MethodsMagnetic resonance imaging (MRI) and haematoxylin ...

Ependymal cells SCOre sweet cerebrospinal fluid.

PLoS Biology, 2023
The subcommissural organ (SCO) is a secretory tissue located on the roof of the brain's third ventricle. A new study published in PLOS Biology finds that the SCO responds to glucose by secreting signaling molecules into the cerebrospinal fluid (CSF ...

Molecular characterization of rabbit phospholipid transfer protein: choroid plexus and ependyma synthesize high levels of phospholipid transfer protein

Journal of Lipid Research, 2002
Phospholipid transfer protein (PLTP) plays an important role in plasma lipoprotein metabolism. However, PLTP is expressed in a wide range of tissues suggesting additional local functions.

Stratification of Spinal Ependyma in Rats in Response to Injury [PDF]

, 2020
The ependymal lining of the central canal in response to injury was investigated in young rats. A unilateral incision on the dorsolateral aspect of the spinal cord (thoraco-lumbar region) was made, after laminectomy, without injuring the ependyma after ...

Intraventricular dysembryoplastic neuroepithelial tumor in the temporal horn with Broad involvement of the ependyma

Clinical Case Reports, 2021
Key Clinical Message Though typical dysembryoplastic neuroepithelial tumors (DNETs) are located in the cerebral cortex, an atypical DNET could occur in the temporal horn of the lateral ventricle and broadly involve the ependyma.

P2X7 receptor activation awakes a dormant stem cell niche in the adult spinal cord

Frontiers in Cellular Neuroscience, 2023
The ependyma of the spinal cord is a latent stem cell niche that is reactivated by injury, generating new cells that migrate to the lesion site to limit the damage.

Neogenin Recruitment of the WAVE Regulatory Complex to Ependymal and Radial Progenitor Adherens Junctions Prevents Hydrocephalus

Cell Reports, 2017
Denudation of the ependyma due to loss of cell adhesion mediated by cadherin-based adherens junctions is a common feature of perinatal hydrocephalus. Junctional stability depends on the interaction between cadherins and the actin cytoskeleton.

Hyperechoic thickened ependyma: sonographic demonstration and significance in neonates.

, 1994
In the neonate, hyperechoic thickening of the ependyma is believed to be related to ventriculitis. Yet, in our experience, this sign is much more often observed in association with subacute intraventricular hemorrhage (IVH), without infection.

Ependymal cell contribution to scar formation after spinal cord injury is minimal, local and dependent on direct ependymal injury [PDF]

, 2017
Ependyma have been proposed as adult neural stem cells that provide the majority of newly proliferated scar-forming astrocytes that protect tissue and function after spinal cord injury (SCI). This proposal was based on small, midline stab SCI.
