Self regeneration of nerve cells

Peripheral nerve injury (PNI) is a very common chronic trauma seen in clinics and is characterized by permanent sensory impairment and severe motor dysfunction...Although peripheral nerve fibers show considerable potential for self-regeneration, the outcome is generally unsatisfactory, resulting in weak motor recovery and irreversible sensory dysfunction.
