ig. 7. Fate map of Xenopus dorsal cranial non-neural ectoderm at the end of neurulation (stage 19/20). Each symbol represents one dye injection, which contributes to precursors of a single placode or epidermis (circle) or to multiple placodes and/or epidermis (square). Black outlined circles and squares represent injections shown in frontal as well as in lateral views. Frontal views are shown in A and C, lateral views in B and D. A, B: Positions of placodal precursors (red symbols) within the non-neural ectoderm in relation to epidermal (light gray symbols) or stomodeal precursors (black symbols). C, D: Positions of precursors for different types of placodes (color coded as indicated). Overlap and co-labeling between anterior placodes has decreased but is still extensive for posterior placodes. Abbreviation: cg: cement gland. For detailed explanation see text.
