Fig. 4

Projection of the lateral line nerve to the opercular neuromasts. HGn39D embryos at 3 dpf (A) and 4 dpf (B). Arrows indicate the sensory axon(s) extending to OP2 (nOP2); arrowheads indicate the point where nOP2 leaves the nAVop. (C) isl1:gfp and atoh1a:dtomato double-transgenic embryo at 4 dpf. (D, E) DiI injection in OP1, in HGn39D (D) and isl1:gfp (E) embryos at 4 dpf, reveals only efferent axons to OP2. Asterisks indicate the sites of DiI injection. Panels A to E are confocal images. (F, G) OP2 injected with DiI at 4 dpf (F) and 5 dpf (G). The position of OP1 is indicated by a dotted line in F. Several neuromasts (OP1, M2, and IO3) are labeled at 5 dpf (G). Inset in G indicates an octavolateralis efferent (Ole) neuron in the hindbrain. (H) Schematic drawing of the opercular lateral line projection. gAV, anteroventral lateral line ganglion. (I, J) Neuromast budding occurs normally in ngn1-MO injected embryos (J) as compared with control embryos (I). Insets show images of the same embryos stained with DiAsp before they were subjected to the immunohistochemistry. Scale bars: 50 μm.
