Peripheral nerve injury regeneration

WebApr 21, 2024 · Unlike CNS nerves, peripheral nerves are capable of spontaneous regeneration after injury. Regeneration occurs when the environment is permissive and the intrinsic growth capacity of neurons is activated. Functional regeneration requires both axon regrowth and remyelination by Schwann cells. WebAug 7, 2024 · Repair of peripheral nerve injury is currently an important research field in neurosurgery and one that presents many difficulties (White et al., 2015). Surgical repair of peripheral nerve injury is different from the unique conditions required for the regeneration of the central nervous system (Hu et al., 2009).
