  Fig. 1. Placodal gene expression patterns in neural plate stage Xenopus embryos (stages 13–14) in dorsal view (anterior is to the left, all embryos are equally oriented). To facilitate comparison of the placodal expression domains of different genes, color-coded arrows and arrowheads corresponding to different placodal expression domains of Pax genes are used for the identification of comparable regions of gene expression (for more detailed labeling, see Fig. 12). Colors are explained in the schematic drawing, which depicts the approximate relative position of some gene expression domains and lists the placodes to which they will give rise subsequently. Green arrowheads identify placodal gene expression immediately rostral to the anterior neural plate border (prospective adenohypophysial placode medially and prospective olfactory placodes laterally), whereas green arrows identify placodal gene expression rostrolateral to the anterior neural plate (prospective lens and trigeminal placodes). Black arrows in D indicate the border of Dlx3 expression in superficial ectoderm, which extends further medial than its border of expression in the deep ectodermal layer (colored arrows). Black arrowheads in E indicate Msx1 expression in anterior neural plate. White asterisks in E and L indicate expression of Msx1 and Pax3, respectively, in a region encompassing neural crest and lateralmost neural plate. For detailed description, see text. Abbreviations: Ad/Ol, anterior placodal area, from which adenohypophysial (Ad) and olfactory (Ol) placodes develop; anp, anterior neural plate; cg, cement gland; L, lens placode; LL/Ot/EB, posterior placodal area, from which lateral line (LL), otic (Ot), and epibranchial (EB) placodes develop; np, neural plate; PN, pronephros; Pr, profundal placode; pnp, posterior neural plate; V, trigeminal placode.
