Influence of nerve on the formation and survival of acetylcholine receptor and cholinesterase patches on embryonic Xenopus muscle cells in culture.


Embryonic Xenopus muscle cells grown in culture develop discrete patches of high acetylcholine receptor (AChR) density. By following identified muscle cells after staining with fluorescent alpha-bungarotoxin, we have found that many of these AChR patches survive in a fixed position for several days. For AChR patches on the lower surface of the cell (the… (More)
