Fig. 5. XHes6 is expressed in the presomitic mesoderm and somitic chevrons. Embryos were analysed by whole-mount in situ hybridisation at early gastrula stage (stage 10.5) (A,C) and tailbud stage (stage 22) (B,D) for expression of MyoD (A,B) and Hes6 (C,D). Both MyoD and Hes6 are found in a ring of prospective mesoderm around the dorsal pore at stage 10.5 (A,C, respectively). At stage 22, MyoD is restricted to myotome but is expressed uniformly throughout (B). Hes6 is found in the eye, brain (asterisk), neural tube, tailbud domain (TBD) and in two to three chevrons anterior to the TBD (arrows, D).
