Stat3 schwann cell axon regeneration
WebResearchers discovered that activation of STAT3 led to better survival of long-term denervated Schwann cells. However, they also found that STAT3 was not required for the … WebEnabling axon regeneration after central nervous system (CNS) injury remains a major challenge in neurobiology. One of the major differences between the injured peripheral nervous system (PNS) and CNS is the pro- and antiregenerative responses of their glial cell populations. In addition to intrinsic qualities of the neurons themselves, glial-driven …

WebSchwann cells play a crucial role in endogenous repair of peripheral nerves because of their ability to dedifferentiate, migrate, proliferate, express growth promoting factors, and myelinate regenerating axons. These cells migrate from the periphery into the injury site, where they apparently participate in endogenous repair processes . WebFurthermore, skin-precursor-derived Schwann cells transplanted into the contused rat spinal cord as late as eight weeks post-injury were shown to mitigate glial scar formation, form cellular conduits to bridge and filled much of the lesions, enhance the presence of endogenous Schwann cells, and myelinate host axons, ultimately significantly ...

WebJan 1, 2006 · Abstract. The Schwann cell plays a vital role in maintaining the peripheral nervous system (PNS). Schwann cells are derived from neural crest cells, and come in two types either myelinating or non-myelinating Schwann cells. Both play a pivotal role in the maintenance and regeneration of axons of the neurons in the PNS.
