Retrograde transport of horseradish peroxidase by regenerating preganglionic axons in the cat's cervical sympathetic trunk.
Horseradish peroxidase (HRP) was applied to the proximal stumps of regenerating (7 days postsectioned) and freshly cut cervical sympathetic trunks of cats. Counts of HRP-labeled neurons in the spinal cord showed that regenerating sympathetic axons were just as capable, if not better able, of taking up and retrogradely transporting HRP, as freshly cut normal sympathetic axons.
