[Effect of the cryopreserved Schwann cells on the peripheral nerve regeneration].

Aim: To compare the effects of primary culture Schwann cells and cryopreserved Schwann cells on the injured peripheral nerve regeneration.

Methods: The primary culture Schwann cells and cryopreserved Schwann cells were transplanted into the silicone tubes that bridged the resected sciatic nerves. At different time after transplantation, HRP was injected into the sciatic nerve trunks at the distal end of the silicone tubes, and then the HRP labeled neurons in dorsal root ganglions and anterior horns of spinal cord were counted.
