Spineless expression in the embryonic PNS. (A) Expression of Ss protein in stage 16 (16–18 h AEL) embryo. Ss is expressed in all sensory neurons in the dorsal (d), lateral (l), ventral prime (v′), and ventral (v) clusters. (B,C) Ss expression is absent in homozygous ss134 (B) and ssD115.7 (C) mutants. (D) Schematic depiction of sensory neurons in the dorsal cluster. Black diamonds represent da neurons, gray circles represent es organs, and white triangles represent bd neurons. (E) All multidendritic (md) neurons in the dorsal cluster in a stage 16 embryo labeled by the E7-2-36 lacZ enhancer trap line as revealed by staining with β-gal. (F) Expression of Ss in the dorsal cluster. (G) Merged image of E and F showing expression of Ss in the da neurons. (H) Quantification of Spineless immunoreactivity (measured as mean pixel intensity) in dorsal da neurons.
