Anti-pJNK antibody immunostaining of pioneer growth cones.
(A,B) Immunostaining for phosphorylated JNK in pioneer axons in wild type (A) and rethu2846 mutants (B) at 30 hpf. pJNK signal in extending pioneer growth cones looks similar between siblings (A’) and mutants (B’). (C) Mean fluorescence intensity measured for the most distal pLLG growth cones (visualized by neurod:EGFP transgene) was compared between sibling (306 ± 26, n = 14) and rethu2846 mutants (290 ± 51, n = 6) at 30 hpf, as not significantly different (p=0.78 by Mann-Whitney U test). Error bars represent S.E.M.
