Ret loss-of-function alters pioneer axon growth cone morphology and protrusion.

(A,B) Lateral view, live image of collective pioneer axon terminals of wild-type siblings (A) and rethu2846 mutants (B) labeled by neurod:EGFP transgene at 30 hpf. (A’,B’) Individual pioneer axons labeled by mosaic expression of neurod5kb:mCherry plasmid (Arrowheads = examples of counted filopodia). (C,D) Quantification of distal collective axon terminal volume (C) or individual pioneer growth cone volume (D). rethu2846 mutants have significantly reduced collective axonal and individual growth cone volume. (E,F) Quantification of number (E) and length (F, n = filopodia counted) of filopodia (≥1 μm) per individual pioneer axon. Note that rethu2846 mutants have significantly reduced number of filopodia but not length. Error bars represent S.E.M.,**=p < 0.01, ***=p < 0.001, N.S. = not significant.
