Distal axotomy often leads to formation of two axons in Class I ddaE neurons. a An axon bundle including the ddaE axon was axotomized at least 20 μm from the cell body (orange arrow). b The same neuron was imaged 96 h after injury. One of the dendrites of the Class I ddaE neuron converted to an axon as indicated by arrows, in addition to re-growth from the axon stump. c Out of 14 axotomized ddaE neurons, 6 grew from the stump and dendrite, 4 grew from the stump only and 4 grew from the dendrite only
