Fig. 10. Comparison of Pax gene expression in Xenopus with placodal fate maps (lateral views). The expression pattern of Pax genes as revealed by in situ hybridization (A–H) were measured at neural plate stages (shown for Pax6 and Pax8: A, E), at the end of neurulation (shown for Pax6 and Pax8: B, F) and in early tail bud stage embryos (shown for Pax6, Pax3, Pax8 and Pax2, C, D, G, H) and compared to fate maps (green encircled areas in A′–H′). A–C and A′–C′: Pax6 expression encompasses precursors for the olfactory, lens, and trigeminal placodes. D and D′: Pax3 expression is restricted to precursors of the profundal placode (placodal expression domain encircled by hatched green line in D). E–G and E′–G′: Pax8 expression is found in precursors of otic, lateral line and epibranchial placodes, but excludes precursors of the vagal epibranchial and posterior lateral line placode. H and H′: Pax2 expression in early tailbud stage embryos is distributed similar to Pax8. Abbreviation: cg: cement gland. For detailed explanation of fate maps, see Figs. 6–8.
