Fig. 5
Regeneration after extended nerve ablation. (A) In nbt-dsred; Sox10-gfp fishes, Schwann cells (arrowheads) extend over the ablated region (double-headed arrow) along the massively defasciculated regenerated axons. (B and C) Nerve ablation over 2?3 somites (double-headed arrows) does not prevent axonal regeneration but results in many axons following alternative courses over the ablated stretches (arrowheads). (Scale bars, 200 μm.)
