Fig. 2. (A) Temporal expression analysis of xArnt during Xenopus embryogenesis analyzed by RT-PCR. Stages of RNA preparations (Nieuwkoop and Faber, 1967) are indicated above each column. Expression is compared with the one of ODC gene. (B) Spatial expression of xArnt analyzed by whole mount and sections in situ hybridization. (a, b) Lateral views of stages 3 and 7 embryos, vegetal pole is at the bottom. A stage 9 embryo (c, d), animal (c), and vegetal views (d). (e, f) Stage 10. Animal (e) and dorso-vegetal (f) views. Stage 28 (g) and stage 35 (h) tail bud embryos, lateral views, anterior to the right. (i) Stage 3, meridian section. (j) Stage 6, meridian section. (k) Stage 12, sagittal section. (l) Stage 14, transversal section. (m–p) Stage 35, transversal sections: optical vesicle (n), otical vesicle (o), and pronephritic duct (m, p). (p) is a high magnification of (m). bdl, blastopore dorsal lip. |
