Schwann cells

(shwahn),
cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves; such cells are comparable with the oligodendroglia cells of brain and spinal cord; like the latter, they may form membranous expansions that wind around axons and thus form the axon's myelin sheath.

Schwann cells

(shwahn selz)
Cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves.
Synonym(s): neurilemma cells, neurolemma cells.

Schwann,

Theodor, German histologist and physiologist, 1810-1882.
Schwann cell unit - a single Schwann cell and all of the axons lying in troughs indenting its surface.
Schwann cells - cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves. Synonym(s): neurilemma cells
Schwann tumor
Schwann white substance - the lipid material present in the myelin sheath of nerve fibers; the medulla of bones and other organs.
schwannoma - Synonym(s): neurilemoma; neuroschwannoma
sheath of Schwann - a cell that enfolds one or more axons of the peripheral nervous system. Synonym(s): neurilemma

The team boosted Schwann cell's nutrition-dispensing capability by injecting a protein gene that promotes nerve growth.
A notable feature of the detached nerve terminals described in this paper is that they are distinguishable from Schwann cells so that they can be patch clamped.
Once the gene that suppresses Schwann cell growth is "mapped" or located, scientists can begin to develop gene therapy to control the overproduction of these cells in individuals with acoustic neurinoma.
Therefore, BMSCs would be more ready to proliferate and differentiate into other kinds of cells, such as osteoblasts, chondrocytes, vascular endothelial cells, and even Schwann cells, under the induction condition [56-58].
In this study, the effect of Wnt5a on Schwann cells was investigated by Wnt5a silencing in RSC96 cells.
On day 7, 21, 28, and 31, vacuolization, degeneration in mitochondria, endoplasmic reticulum and Schwann cells, neurofilaments, and lack of organelles in the axoplasm occurred.
The optic nerve and its sheath are innervated by sympathetic fibers that are myelinated by Schwann cells these are a potential source.6 Another possible source is the sympathetic fibers supplying the central artery in case of schwannomas located more centrally within the structure.7 There is also speculation that there exist aberrant Schwann cells that may give rise to tumours but this appears far less likely.
We retrospectively describe our 5-year experience in using confocal laser scanning microscopy (CLSM) to differentiate the morphological features of Schwann cells at the time of first resection of neurofibromas arising in NF1 patients (study registration number: researchregistry3681).
