WebSchwann cells are the main glial cell in the PNS and play an essential role in the survival and functions of neurons. In response to nerve injury, Schwann cells undergo rapid changes in phenotype [199] and their basal lamina provides a conduit for axon regrowth, a critical process for nerve regeneration. Web27 Jan 2024 · Schwann cells in the central nervous system In this review, we focus on the intriguing observation that SCs, the myelinating cells of the PNS, can also be detected in the CNS of multiple sclerosis (MS) [ 4, 6, 7 ], neuromyelitis optica [ 8] and in spinal cord injury patients [ 9 – 11 ].

After peripheral nerve injury, mature Schwann … Schwann cells are a variety of glial cells that keep peripheral nerve fibres (both myelinated and unmyelinated) alive. In myelinated axons, Schwann cells form the myelin sheath. The sheath is not continuous. Individual myelinating Schwann cells cover about 1 mm of an axon —equating to about 1000 Schwann cells along a 1-m length of the axon. The gaps between adjacent Schwann cells are called nodes of Ranvier.
