Fig. 2 The HuC promoter drives the expression of mem-TdTomato in the afferent neurons.
Maximal projections of HGn39D fish injected with HuC:mem-TdTomato are depicted. (A) HuC promoter drives the expression of mem-TdTomato in the soma of the afferent neurons (HB: hinbrain, gP: Posterior lateral-line ganglion). (B–C) mem-TdTomato is expressed in GFP-positive neurons of HGn39D fish at the level of the defasciculated fibers (B) and of the dendrites beneath the neuromast (C). (D) mem-TdTomato is expressed in a single neurons. (E–G) Injection of HuC:mem-TdTomato allows the mosaic expression of red neurons. A single red neuron (E) can be observed in HGn39D (F). (G) Overlay of HGn39D GFP and mem-TdTomato. Scale bars: 50 μm (A) and 10 μm (B–G).
