[An update of repairing spinal cord injury by olfactory ensheathing cells]

The treatment of spinal cord injury is always a stubborn problem for neurosurgeons because nerve cell cannot regenerate and the glia scar can prevent the axonal regeneration. Olfactory ensheathing cells (OECs) is a kind of especial glia cell, which possesses the character of horizontal cell of central nervous system and schwann cell. Many foundational and clinical studies showed that the olfactory ensheathing cellscan promote axonal regeneration and prove axonal growth, some progress is made and this is bringing hope for treatment of spine injury.
