ABSTRACT
Experiments in rats, introducing the proximal and distal stumps of tibial and sural
nerves into a vein graft, showed by acetylcholinesterase and toluidine blue staining
that sensory and motor fibers mix inside the vein graft, but that nevertheless they
are able to select their distal targets correctly. The authors' hypothesis is that
surface membrane antigens of Schwann cells might be responsible for this chemotactic
phenomenon.
