The chemosensitivity ofXenopusmuscle cells grown in culture to iontophoretically applied acetylcholine (ACh) in the presence or absence of neurons was examined. Muscle cells grown without nerve cells are sensitive to ACh over their entire surface (2.4 mV/pC) with occasional spots of high chemosensitivity (“hot spots”). In cultures containing neural tube cells, the ACh sensitivity of muscle cells increased by approximately 50% regardless of the presence of nerve contacts or functional synapses. A similar increase in the ACh sensitivity was observed in muscle cells cultured in medium conditioned by neural tube cells. The ACh sensitivity of the extrajunctional region in functionally innervated muscle cells was not different from that of noninnervated cells growing in the same cultures. However, the chemosensitivity at the junctional region was about fivefold higher than that of the extrajunctional area. This increase in junctional chemosensitivity may well account for the increase in miniature endplate potential amplitude which has previously been reported to occur during nerve-induced ACh receptor accumulation.
