Detailed explanation-1: -Together the activation of the de‐differentiation and repair programmes recasts Schwann cells of intact nerves as cells that are equipped in a number of ways to promote regeneration, namely as repair (Bungner) Schwann cells. These cells ensheath axons and transform back to myelin and Remak cells in regenerated nerves.
Detailed explanation-2: -Schwann cells (SCs) are the major glial cell type in the peripheral nervous system. They play essential roles in the development, maintenance, function, and regeneration of peripheral nerves. In the mature nervous system, SCs can be categorized into two major classes: myelinating and nonmyelinating cells.
Detailed explanation-3: -Schwann cells are a type of glial cells of the peripheral nervous system that help form the myelin sheath around the nerve fibers.
