n.
Any of the cells that surround the axons of the peripheral nerves, forming the myelin sheath of myelinated nerve fibers and providing support for nonmyelinated nerve fibers. Also called neurilemma.

Schwann cell

A NEURILEMMA cell of a nerve fibre that produces the myelin sheath. (Theodor Schwann, 1810–1882, German anatomist).

Schwann cell

a type of cell occurring in the region of the nerve fibres of the peripheral nervous system of vertebrates. It produces the neurilemma which encloses the MYELIN SHEATH (see Fig. 226 ), and is found in close contact with the nerve axons between each node of Ranvier. see SCHWANN.

In the present study, S-100 was used because it represented an easy marker, has been widely used in the identification of schwann cells, and aids greatly in the diagnostic process.
Schwann cells of the olfactory nerves contain glial fibrillary acidic protein and resemble astrocytes.
(2002) proposed that the mutated GDAP1 might prevent the correct catalysing S-conjugation of reduced glutathione (antioxidant), resulting in a progressive attrition of both axons and Schwann cells. Mutations in the small GTP-ase late endosomal protein RAB7 have also been related with axonal neuropathy.
In addition, where to obtain Schwann cells can be a problem; the cells can be cultivated from a trace sample taken from humans, or can be cultivated from embryonic stem cells.
Scientists believe that this particular gene on chromosome 22 suppresses the growth of Schwann cells. When this gene malfunctions, Schwann cells can grow out of control.
It should be noted that DRG cells contained both sensory neurons and Schwann cells in our experiment, although DRG explants had been shredded and digested.
