FIG. 4. Analysis of Xwnt-SA expression in the developing auditory system. Embryos at several stages of development were hybridized with an Xwnt-3A antisense probe and processed as described in Fig. 3. (A) Transverse section through a stage 19 embryo. Hybridization signal is localized to the sensorial neural ectoderm (arrows; SN). (B) Transverse section through the otic placode of a stage 22 embryo. Xwnt-3A expression is localized to the dorsal most portion of the placode in close proximity to the developing rhombencephalon (arrow; R). (C and D) Transverse sections through stage 31 and 46 embryos, respectively. Xwnt-3A expression is localized to the dorsal most portion of the otic vesicle (arrows). Abbreviations: N, notochord; NT, neural tube; OP, otic placode; OV, otic vesicle; R, rhombencephalon; S, somite; SM, somitic mesoderm; SN, sensorial neurectoderm. Bar = 50 ~m.
