  Fig. 3. Spatial expression profiles of polypyrimidine tract binding protein (PTB) genes during early Xenopus development. Whole-mount in situ hybridization was performed to study the spatial expression of ptbp1, ptbp2 and ptbp3 at different developmental stages.

  Fig. 4. Spatial expression profiles of polypyrimidine tract binding protein (PTB) genes in late tailbud embryos. Whole-mount in situ hybridization followed by longitudinal and transverse sections were performed to examine the spatial expression of ptbp1, ptbp2 and ptbp3 in late tailbud embryos. (A) ptbp1 (a) lateral view of a stage 34 embryo, the white lines indicate the level of transverse and longitudinal sections shown in panels b-i, (b-d) longitudinal sections of the head along the dorso to ventral axis, (c longitudinal section of the trunk realized at the same level as panel c, (e-i) transverse sections along the anterior to posterior axis, (i higher magnification view of panel i. Black arrowheads point to the CMZ of the retina (B) ptbp2 (a) lateral view of a stage 34 embryo, the white lines indicate the level of transverse and longitudinal sections shown in panels b-g, (b-d) longitudinal sections of the head at the level of the brain, (d longitudinal section of the trunk realized in the same plan as panel d, (e-g) transverse sections of head and trunk. Black arrowheads point to the neuronal retina. (C) ptbp3 (a) lateral view of a stage 34 embryo, the white lines indicate the level of transverse and longitudinal sections shown in panels b-j, (b-d) longitudinal sections of the head along the dorso to ventral axis, (c longitudinal section of the trunk realized at the same level as panel c, (e,f) transverse sections of the head at the level of the diencephal. (g,h) higher magnification views of transverse sections of the head at the level of the rhombocephal, (i,j) transverse sections of the trunk, (j higher magnification view of panel j. Black arrowheads and arrows point respectively to the posterior lens and the hypothalamic labeling. Abbreviations used are: da, dorsal aorta; di, diencephal; dm, dermatome; h, heart; im, intermediate mesoderm; m, myotome, nc, notochord, ov, otic vesicle; rb, rhombocephal; sc, spinal cord; va, ventral aorta.
