From: The recombination activation gene 1 (Rag1) is expressed in a subset of zebrafish olfactory neurons but is not essential for axon targeting or amino acid detection

Figure 3

Expression of G alpha subunits in larval olfactory neurons.(A-C) Gαo (red fluorescence, C) is present in a subset of Rag1-expressing cells (green fluorescence, B; arrowheads) isolated from the olfactory epithelium of a Rag1:GFP zebrafish. A cell with bright GFP (arrow), however, does not contain Gαo. (D) Gαq-positive neurons (arrows) do not express GFP, and vice-versa. Axons are strongly labelled (arrowhead). (E) A crypt cell (arrowhead), with Gαq label in the dendrites, lacks GFP. Two cells with bright GFP (arrows), in contrast, lack Gαq label. (F) Gαolf label, seen here in axons and some cell bodies (arrowheads), was not detected in cells strongly expressing GFP (arrows). Bar = 5 μm (A-E); 10 μm (F).
