|Fig. 1. pqbp1 and wbp11 genes are similarly expressed in mesoderm and neural tissues during Xenopus development. (A) WISH detection of pqbp1 and wbp11 transcripts in 64-cell blastula, neurula and tailbud tadpole; lateral views except anterior (ant) view of neurula. (B-E) WISH on intact (C,E) or longitudinally bisected (B,D) embryos with probes indicated. Asterisks mark the dorsal blastopore lip. (B) pqbp1 transcripts are present in the animal pole ectoderm and marginal zone in early gastrula (stage 10.5), upper panel; sense probe, lower panel. (C) Expression of pqbp1 and chordin in gastrulae, stage 11.5. (D) Expression of pqbp1, wbp11, chordin and sox2 in late gastrulae, dorsal-posterior views. Expression of pqbp1 overlaps with chordin in dorsal/axial mesoderm (arrows) and with sox2 in anterior neurectoderm. (E) Expression of pqbp1 and ncam mRNA in the neural plate of early neurula embryos. Note pqbp1 expression is in a broader region than ncam. an, anterior neurectoderm; chd, chordin; S, pqbp1 sense probe.|
