5 cells) as neuroblasts
were easily found in the SGZ of the DG [Figure 2]A.
Drosophila neural stem cells, The neuroblasts
(nb), Are a fantastic model of temporally and metabolically regulated cells.
In aborted human foetuses collected from endemic fluorosis area, it was found that accumulation of fluorides in brain tissue causes disruption of certain neurotransmitters and receptors in nerve cells and also increased numerical density of volume of nerves and undifferentiated neuroblasts
The condition develops from nerve cells called neuroblasts
, which are left behind from a baby's growth in the womb.
The disease develops from nerve cells, known as neuroblasts
, which get left behind from the child's development in the womb.
SNH was initially thought to be a neuronal migration disorder characterized by nodules of neurons due to arrested migration or failure of neuroblasts
to undergo apoptosis,[sup] but according to recent research, neuroependymal injury, rather than an intrinsic motility defect of the cell, is thought to be an important pathogenetic factor in the development of SNHs.
The change in the cell population during differentiation was corroborated by the measurement of doublecortin (DCX), a microtubule-associated protein expressed in neuroblasts
and immature neurons: The number of DCX-positive cells in NPC (week 0) was around 30%, which dropped to 22% at 2, 17% at 4 and 4% at 8 weeks, respectively.
23,24) We have previously shown that Notch ligands such as delta like 1 (Dll1) and jagged1 (Jag1) are expressed in NSC-produced neuroblasts
or immature neurons, and they activate Notch signaling in adjacent remaining NSCs.
Histologic examination of the mass revealed neoplastic proliferation infiltrating the adjacent cerebellar tissue; the mass was composed of a mixture of neuroblasts
arranged in a cohesive pattern and numerous cells with neuronal features (ganglion cells) interspersed with delicate stroma.
Identification and characterization of neuroblasts
in the subventricular zone and rostral migratory stream of the adult human brain.
During embryonic development of the brain, neuroblasts
migrate away from the germinal layer of the ventricular neuroepithelium, mostly along the tracks of radial glial fibres.
The migration of neuroblasts
that will form the myenteric plexus begins in small intestines at I.
