Fig. 3. Fate map of Xenopus non-neural ectoderm at neural plate stages using tissue grafts. A: Example of pigmented graft transplanted into albino host at stage 14 (left panel) and then followed throughout development until mid-tailbud stage (right panel). B: Example of tailbud stage embryo that had received a Hoechst labeled graft at the neural plate stage. C: Changes of shapes of three grafts (blue, yellow, red) between stage 14 (left), stage 22 (middle) and stage 24 (right) projected onto outlines of Xenopus embryos (Nieuwkoop and Faber, 1967). Note the wedge shaped expansion of the anterior graft. D: Summary of placodal fates adopted at tailbud stages (stage 39) by grafts from the indicated positions at neural plate stages. Data are compiled from pigmented and Hoechst-labeled grafts as indicated. Due to the close apposition of some placodes or their derivatives at tailbud stages – viz. the trigeminal and profundal placodes, the anterodorsal and anteroventral lateral line placodes, and the facial and glossopharyngeal epibranchial placodes – it was often not possible to determine whether one or both of these placodes were labeled by a graft and we, therefore, only noted whether any of them were labeled.
