materials into the lumbar epidural space were not autografts, but were allografts resected
from another Sprague-Dawley rat. The reasons for using allografts in this study are 1) it is
necessary to prevent lumbar kyphotic deformity after resection of the lumbar intervertebral
discs, and 2) it is difficult to harvest sufficient intervertebral disc tissue from three levels in
the lumbar spine of the same experimental rat. Rats in the fat group showed evidence of …
