Reinnervation of original synaptic sites on muscle fiber basement membrane after disruption of the muscle cells.

Abstract

Regenerating axons form new synapses precisely at sites of original synapses in denervated skeletal muscle. To determine what role the muscle cell plays in this phenomenon, we studied reinnervation of frog muscle at intervals after crushing the nerve and damaging the muscle fibers. Damaged muscle fibers degenerate and are phagocytized, but their basement… (More)
