neuroepithelium

The neural tube becomes the germinal neuroepithelium and serves as a source of new neurons during brain development.

Pioneer neurons are born in the ventricular neuroepithelium all over the cortical primordium.

Unlike a mature teratoma, it contains primitive neuroepithelium.

Instead, the embryos possessed a neuroepithelium that gradually tapered towards the diencephalon (Fig. 2).

In the early developmental stages of the neural tube, segmentation of the neuroepithelium occurs.

OPCs originate from the neuroepithelium of the spine and migrate to other areas of the brain.

Astrocytes are derived from heterogeneous populations of progenitor cells in the neuroepithelium of the developing central nervous system.

The olfactory neuroepithelium, which lines the posterior nasal cavity, is exposed to a wide range of odorants and airborne toxic compounds.

The upper portion of the nasal chambers contain the sensory receptors responsible for olfaction, and are situated in a neuroepithelium which lines the cribriform plate.

Directly beneath this epithelium is the neuroepithelium (i.e., rods and cones)passes jointly with the RPE.

Inside the nasal chambers is the neuroepithelium, a lining deep within the nostrils that contains the receptors responsible for detecting molecules that are small enough to smell.

Esthesioneuroblastoma (olfactory neuroblastoma) is a very rare, small round-cell tumor arising from the nasal neuroepithelium that is distinct from primitive neuroectodermal tumors.

An example of tangential migration is the movement of Cajal-Retzius cells from the cortical hem to the superfitial part of cortical neuroepithelium.

V1Rs, V2Rs and FPRs are seven transmembrane receptors which are not closely related to odorant receptors expressed in the main olfactory neuroepithelium.

Next, dentate precursor cells move out of this same area of the hippocampal neuroepithelium and, retaining their mitotic capacity, invade the hilus (core) of the forming dentate gyrus.

The resultant patterning along the neuraxis leads to segmentation of the neuroepithelium into progenitor domains (p0, p1 p2, p3 and pMN) for distinct neuron types in the developing spinal cord.

NSCs are differentiated into new neurons within the SVZ of lateral ventricles, a remnant of the embryonic germinal neuroepithelium, as well as the dentate gyrus of the hippocampus.

Once the cells in the neuroepithelium detect a stimulus, a signal is sent up the cranial nerve and travels to the olfactory bulbs in the brain where the initial processing of olfactory information occurs.

Subsequently, neural crest cells from the roof plate of the neural tube undergo an epithelial to mesenchymal transition, delaminating from the neuroepithelium and migrating through the periphery where they differentiate into varied cell types.

Prior to neurulation, during the migration of epiblastic endoderm cells towards the hypoblastic endoderm, the notochordal process opens into an arch termed the notochordal plate and attaches overlying neuroepithelium of the neural plate.

The oldest granule cells are generated in a specific region of the hippocampal neuroepithelium and migrate into the primordial dentate gyrus around embryonic days (E) 17/18, and then settle as the outermost cells in the forming granular layer.

The first real evidence that precerebellar neurons had a dorsal origin was obtained in the 1990s through the use of chick-quail chimeras, a technique in which portions of quail hindbrain neuroepithelium are grafted into chick embryos in ovo.

This neuronal organization is unique to the r4/5 region and in r2/3 we found that trigeminal efferent neurons traced from the exit point in r2 are more laterally placed, with their axons all extending laterally through the neuroepithelium (Fig. 2b, f ).
