Details:
Traumatic spinal cord injury (SCI) causes partial or complete functional loss below the injury site. Patients with SCI suffer lifelong disability and require continuous physical and medical care. SCI causes neuronal loss and axon degeneration, which disrupts the neural circuitry that controls the functions of spinal cord. In the central nervous system (CNS), neurons usually cannot renew themselves to replace the lost neuron population, and achieving long-distance axon regeneration from the remaining neurons is extremely difficult.

Neural stem/progenitor cells (NSPCs) transplantation is a promising therapeutic strategy to replace lost neurons and establish neuronal relays, facilitating the reconstruction of damaged neural circuitry. However, the formation of astroglial-fibrotic scars impedes axon growth and integration of NSPC grafts into the host tissue. Oxidative stress plays a critical role in the progression of cell death and tissue damage after SCI. In this study, we aim to reduce scar formation and promote NSPC survival and enhance graft-host integration after SCI.
