Fig. 3. Anti-acetylated tubulin immunoreactivity within Rohon-Beard peripheral processes differs between touch-insensitive mao mutant and sibling embryos at late but not early times. The peripheral processes of sibling control (A) and mao mutant (C) embryos displayed similar patterns of aat immunoreactivity (arrows) at the initial stages of touch sensitivity (compare with Fig. 1A,B). However, at 48 hpf, the pattern of aat immunoreactivity of mao mutants (D) differed from that of sibling controls (B) and resembles that observed at earlier stages in either sibling, mutant or wild-type embryos (Fig. 3A,C, 1A,B). In all examples, images were taken from skin regions at caudal levels of the spinal cord. Scale bar: 20 µm.
