Fig. 5. Tail regionalization. Whole-mount in situ hybridizations were carried out on tailbud embryos. The tail region in lateral view and vibratome sections thereof are shown. (A) Show selected marker gene expression, (N and O) show diagrams summarizing the identified domains in mid-sagittal and frontal view, respectively. Where indicated, frontal (f, posterior to the right), sagittal (s, posterior to the right), or transverse (t, dorsal to the top) vibratome sections are shown. Abbreviations: acnh, anterior chordoneural hinge; cnh, chordoneural hinge; end, endoderm; fs, forming somites; if, inner fin; mcnh, mid chordoneural hinge; of, outer fin; nec, neurenteric canal; pag, post-anal gut; pcnh, posterior chordoneural hinge; psm, presomitic mesoderm; pnc, posterior notochord; pw, posterior wall; scf, spinal cord floor; scr, spinal cord roof; so, somites; tpw, tip of posterior wall; vpw, ventral posterior wall.
