Fig. 6. Spatial expression pattern of xtTAZ during the early development of Xeno- pus tropicalis. (A-N) Spatial expression of xtTAZ was analyzed by whole-mount in situ hybridization. Late neurula stage in (A) dor- sal view and (B) anterior view, (C) early tailbud stage, (E) tailbud stage, (F) late tailbud stage, and (G) tadpole stage in lat- eral view. (D) Transverse section of (A). (H, J, K) Transverse section of (E). (I, M) Trans- verse section of (F). The line position is indicated in (E-G). (L) Higher magnification of (K). (N) Higher magnification of (M). The box position is indicated in (K,M). Scale bars, 50 m. Abbreviations: ba, branchial arch; fm, facial musculature; hb, hindbrain; ht, heart; hm, hypaxial myoblasts; mh, mid- brain-hindbrain boundary; nt, notochord; pm, paraxial mesoderm; ps, presomitic meso- derm; sc, spinal cord; so, somite. |
