Influence of autograft size on peripheral nerve regeneration in cats.
A combination of electrophysiological and histological techniques has been used to study the extent to which the size of an autograft affects myelinated axon regeneration in damaged cat peripheral nerves. The length of the graft and the match between the number of axons and Schwann cell basement membrane tubes in the graft and the repaired nerve were investigated. No difference was found in the success of regeneration through 10, 20 and 30 mm autografts. Changing the number of Schwann cell tubes available to regenerating myelinated axons also had no detectable effect on the success of regeneration.
