Fig. 4

Pectoral fin muscles are predisposed to form large AChR clusters. (A) Motoneuron cell bodies from spinal cord (SC) segments 3-5 were laser ablated at 2 and 3 dpf to prevent motor axon innervation of the dorsal pectoral fin. (B) Pectoral fins from control Tg(mnx1:GFP) larvae stained with α-Btx to label AChRs. (C) Pectoral fins from Tg(mnx1:GFP) WT larvae after motoneuron ablation at 120 hpf (5 dpf). The ventral fin is innervated (white-dashed region) with input from unablated nerve 4 (segment 6). The non-innervated dorsal region of the fin has enlarged AChR clusters.
