摘要：Clusters of membrane particle aggregates were found in the cultures of Xenopus embryonic muscle cells. In innervated cultures, the aggregates were usually found in the vicinity of the nerve. In terms of particle density and morphology, they resembled the postsynaptic particle aggregates of adult skeletal muscle fibers, suggesting that they may be related to acetylcholine receptors. Similar particle aggregates were also found in noninnervated cultures. They may correspond to extrajunctional clusters of acetylcholine receptors or "hot spots."
