Abstract
Nerve regeneration in the central nervous system has been studied by grafting various tissues and cells. Choroid plexus epithelial cells represent a continuation of ventricular ependymal cells and have the same origin as regarded as modified ependymal cells. To study the use of choroid plexus ependymal cell grafting for nerve regeneration in the spinal cord, the choroid plexus was excised from the lateral and fourth ventricles of adult Sprague-Dawley rats, minced into small fragments, and grafted at the T9 level in adult rat spinal cord transected or contused. In this study, transplants of choroid plexus ependymal cells were successfully used to promote functional and structural recovery after spinal cord transection and contusion. The area of damaged spinal cord was diminished after choroid plexus ependymal cells transplantation. Nearly normal anterior horn cells were observed immediately distal to the transected region. Tyrosine hydroxylase immunoreactive descending fibers were observed in the distal region beyond transected area. These findings indicate that choroid plexus ependymal cells have the ability to facilitate axonal growth, suggesting that they may be a promising candidate as graft for the promotion of nerve regeneration in the spinal cord.
