Fig. 8.

AnkB, α2- and β2-spectrin are not restricted to the distal part of motor axons. Immunolabeling of AnkG (with rabbit anti-AnkG) (a1–f1), AnkB (a2–b2), α2-spectrin (c2–d2) and β2-spectrin (e2–f2) in the spinal cord (delimited by dashed lines). At E10.5, AnkG (a1, c1 and e1), AnkB (a2), α2-spectrin (c2) and β2-spectrin (e2) were expressed in the ventral root (arrowheads). At E13.5, AnkB (b2), α2-spectrin (d2) and β2-spectrin (f2) were expressed both along the ventral root and in some AnkG⁺ segments in the spinal cord (arrows). The asterisk in a3 indicates the dorsal root. Scale bar represent 25 μm
