The potential for axonal repair varies. In the peripheral nervous system (PNS), axons have a higher capacity to regenerate due to the presence of Schwann Cells which promote axonal growth. However, in the central nervous system (CNS), axonal regeneration is limited due to factors such as the presence of inhibitory molecules and the lack of supportive cells like Schwann cells. Research is ongoing to find ways to enhance axonal repair in the CNS, including the use of growth factors, stem cell therapy, and biomaterials.
