1. Whole-mount in situ hybridization analysis of pdzrn3 during Xenopus laevis development. Nieuwkoop-Faber stages (st) of embryogenesis are indicated at the bottom right corner of each panel. The analysed genes are indicated at the top right corner of each panel. Abbreviations: branchial arches (ba), cement gland (ce), central nervous system (CNS), cloaca (cl), cranial ganglia (cg), eye vesicle (e), heart (h), otic vesicle (ov), pronephric anlagen (p), pronephric duct (pd), pronephric proximal tubules (pt), somites (s), spinal cord (sc), trigeminal anlagen (tr). (A,D) Dorsal views of pdzrn3 hybridized embryos during neurulation; black arrows indicate the specific pdzrn3 signal. (E-E’’) Comparison of embryos hybridized with pdzrn3, hnf1b and pax8 (lateral views, anterior left); black arrowhead in (E) underlines the pdzrn3 signal below the somites; black arrow indicates the specific pdzrn3 signal in the ventral region. (F,F’) Comparison of embryos hybridized with pdzrn3 and hnf1b. Somites numbers 2, 3, 4 are indicated and the ventral region is pointed by the arrow. (G-G’’) Ventral views of embryos hybridized with pdzrn3, hnf1b and Nkx2.5. In (G) the white bracket indicates the ventral region and white arrowheads point to a region below the ce gland. The ce is dashed in (G’). (H) Lateral view, anterior to the left and (I) ventral view (head to the top) showing the strong signal in the ventral region of embryos (white bracket); open arrowheads point to specific regions of the CNS. (J,K) Lateral views of the developing pronephros at st. 33-34 and 37-38. The dashed box in (K) corresponds to the enlarged view in panel (N). (L) Complete view of the embryo at st. 37-38. (M-Q) Details of specific domains of expression. White brackets in (L), (M) and (M’) indicate the liver anlagen. (N) Enlargement of (K) dashed box. (O) Particular of the embryo head; open arrowheads: the regions of the CNS already detectable at st. 28. (P) Particular of the dorsal fin cells are highlighted in dashed box. (R) Transversal section of embryo, showing specific pdzrn3 signal in glomus (red arrows) and tubules (blue arrows). (S) Schematic representation adapted from Vize et al., (1997). Scale bars: A-E’, 150 mm; F-G’’,R, 250 mm; I,M,M’, 300 mm; H,J,K,L,O-Q, 500 mm. |
