Axonal regeneration proceeds through specific axonal fusion in transected C. elegans neurons



A C. elegans mechanosensory neuron expressing GFP undergoes regenerative growth following laserinduced injury. A growth cone, sprouting from the proximal side of the axon, extends towards the separated distal fragment in an attempt to reconnect and fuse. The fluorescent image was digitally duplicated twice and re-colored (Graphic designer: Dee McGrath). From Neumann et al., Developmental Dynamics 240:1365–1372, 2011
