Abstract
Severed adult rat dorsal roots were apposed to an intraspinal transplant of fetal spinal cord (FSC) tissue co-grafted with nerve growth factor (NGF)-treated nitrocellulose strips. Axonal regrowth from the injured roots was assessed by calcitonin gene-related peptide immunoreactivity (CGRP-IR). Dense fascicles of regenerating CGRP-IR axons lined the entire length of NGF-treated nitrocellulose, with many crossing the graft host interface ventrally to extend into the host neuropil. In contrast, CGRP-IR axon regrowth was not promoted by untreated nitrocellulose implants. These results indicate that substrate bound NGF can promote and direct the intraspinal regeneration of a specific population of dorsal root axons.
