Wnt signaling pathway is one of the important signal transduction systems that involved in regulating nervous system devel-opment, which plays an important role in axonal regeneration, neural stem cell proliferation and differentiation into neurons and inhibition of differentiation into glial cells. After spinal cord injury, multiple Wnt protein expresses around the injury site, and some proteins of the Wnt family play an important role in spinal cord injury repair, in which the activation of Wnt/β-catenin signaling pathway is necessary for spinal cord regeneration after spinal cord injury.

The Notch signaling pathway plays a pivotal role in the process of neurogenesis in central nervous system. It not only maintains the appropriate number and proportion of neurons and glial cells in the growth and development of embryo, but also regulates the injured neural stem/progenitor cells to differentiate into neurons/glial cells of the adult nervous system, promoting the repair of the nervous system.
