Fig. 6. Transgenic overexpression of dnPlexinA4-GFP in the Rohon-Beard neurons
caused reduction in the number of branching of the peripheral axons of
Rohon-Beard neurons. Anti-acetylated
-tubulin antibody staining of 26
hpf embryos of the transgenic zebrafish (B), which expresses dnPlexinA4-GFP
fusion protein in the Rohon-Beard neurons (black circles), showed significant
reduction in the number of branching points of the peripheral axons compared
with that in the normal 26 hpf embryo (A,C), especially in the D2 region (D).
