Fig. 2. Spatial expression of X.tropicalis HNF6. Neural expression of HNF6 (A-G) and endoderm expression (H,J). Embryos at st. 17 (A,B), st. 22 (C), st. 24 (D,E), st. 25 (F,H,I,J), st. 32 (G) are shown. The embryo in (A) was bisected along the midline, the anterior region is identified by the presence the pigmented cement gland (Ce). The region highlighted by the rectangular box is shown at higher magnification in (B). (C,F,G) Expression in the cranial region. (D,E) Coronal sections. (H) St. 25 embryo, solid line showing the plane of section of wax section (I) and bisected embryo (J). Abbreviations: A, anterior; AD, anterodorsal lateral line placode; AVE, anterior ventral endoderm; Ce, cement gland; D, dorsal; E, eye; F, foregut; M, middle lateral line placode; N, notochord; NT, neural tube; P, posterior; PV, trigeminal placode; Po, posterior lateral line placode; SP, sensory placodes; V, ventral. |
