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.

Synonym(s): neurilemma cells, neurolemma cells

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].

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.
