Conclusion
The CSCB has an evident therapeutic effect by facilitating peripheral nerve infiltrating following the severe spinal cord injury in canine animals.
Methods
A total of 24 adult female beagle dogs received a complete spinal cord transection at the T12 level in three groups, including SHAM group (n=8), CTL group (complete spinal cord transection without any treatment, n=8) and CSCB group (complete spinal cord transection with CSCB, n=8).
Results
CSCB therapeutic group showed markedly functional recovery by Olby score and spinal somatosensory evoked responses (SSERs) assay at 12 weeks after complete spinal cord transection. Furthermore, numerous peripheral myelinated axons aligned parallel to the long axis of the spinal cord were detected in CSCB group dogs. In stark contrast, the injured site was dominated by fibrous and only scattered axons were detected in the edge of spinal cord in CTL group dogs.
