Additional file 3. St. 22 Hex-expressing anterior ventral endoderm is fated to give rise to liver precursors. A: st. 22 embryo, hybridised with Hex probe, is aligned along a graticule. B: strategy used for fate mapping the st. 224 Hex expressing ventral endoderm domain. In brief, embryos were aligned along the graticule using the pharyngeal arches, cement gland and a ventral protrusion as landmarks. The embryo was bisected caudal to the pharyngeal arches and the ventral protrusion and a small spot of DiI (Sigma) injected onto the exposed ventral endoderm. Bisected embryos were then grown until they reached st. 35. In situ hybridisation was performed to ascertain whether the position of the DiI corresponded to the position of Hexexpression. C, D: visible and fluorescent light views of st.35 half-embryos. E: merged images C, D. F: in s Image published in: Haworth KE et al.
