Fig. 6. Whole-mount in situ hybridization showing the endogenous localization of Xhl mRNA during gastrulation and neurulation, respectively. (A)
Dorsal-posterior view of an embryo at late gastrula stage 12. Xhl mRNA is predominantly located to the midline of the neural plate. (B) Dorsal view of
a stage 13 early neurula embryo showing the localization of Xhl mRNA in the midline of the neural plate. Anterior to the top. (C) Same view of a midneurula
stage 15 embryo as in (A) demonstrating that Xhl mRNA is localized in the neural groove of the up-folding neural plate. Space bars are
