Resection of glial scar following spinal cord injury.
While many studies have focused on modulating the immune response and enhancing axonal regeneration after spinal cord injury (SCI), there is limited work being performed on evaluating the role of glial scar in SCI. We sought to evaluate the effects of glial scar resection in contusion models and dorsal hemisection models of SCI. At 1-week postinjury, 2 mm of glial scar was excised from specimen...
متن کاملUnderstanding the NG2 Glial Scar after Spinal Cord Injury
NG2 cells, also known as oligodendrocyte progenitor cells, are located throughout the central nervous system and serve as a pool of progenitors to differentiate into oligodendrocytes. In response to spinal cord injury (SCI), NG2 cells increase their proliferation and differentiation into remyelinating oligodendrocytes. While astrocytes are typically associated with being the major cell type in ...
متن کاملP 94: The Systemic Inflammation after Spinal Cord Injury
Spinal cord injury (SCI) actuate to complex cellular and molecular interactions within the central nervous system in a heave to repair the initial tissue damage. The pathophysiology of acute spinal cord injury (SCI) involves primary and secondary mechanisms. Neuroinflammation is an important secondary injury process in SCI. The local inflammatory microenvironment within the injured spinal cord ...
متن کاملA Mathematical Model of Regenerative Axon Growing along Glial Scar after Spinal Cord Injury
A major factor in the failure of central nervous system (CNS) axon regeneration is the formation of glial scar after the injury of CNS. Glial scar generates a dense barrier which the regenerative axons cannot easily pass through or by. In this paper, a mathematical model was established to explore how the regenerative axons grow along the surface of glial scar or bypass the glial scar. This mat...
متن کاملSelf-assembling nanofibers inhibit glial scar formation and promote axon elongation after spinal cord injury.
Peptide amphiphile (PA) molecules that self-assemble in vivo into supramolecular nanofibers were used as a therapy in a mouse model of spinal cord injury (SCI). Because self-assembly of these molecules is triggered by the ionic strength of the in vivo environment, nanoscale structures can be created within the extracellular spaces of the spinal cord by simply injecting a liquid. The molecules a...
