Z-stack movie showing a whole-mount view of the eye region of a 3-dpf Tg(crestin:creERT2);Tg(-3.5ubi:loxP-GFP-loxP-mCherry) embryo, immunostained for serotonin and mCherry. Serotonergic cells are scattered in the epidermis over the eye, as reported (Coccimiglio and Jonz, 2012), but none is mCherry-positive, i.e., neural crest-derived. Video 2 shows a higher-power movie. A three-dimensional rendering for the eye is shown in Figure 2—figure supplement 1.
