Fig. 7. Ectopic expression of foxi1. Anterior is to the left. (A,B) Dorsal views of control embryos labeled with phox2a and ngn antisense RNA probes, respectively. (C-F) 24 hpf foxi1-injected embryos, labeled with (C) phox2a, showing ectopic phox2a⁺ cells on the yolk surface (arrows); (D) ngn, showing ectopic ngn⁺ cells on the yolk surface (arrow); (E) foxi1 (red) and phox2a (purple), showing that phox2a⁺ cells do express ectopic foxi1; (F) foxi1 (red) and ngn (purple), showing that ngn⁺ cells do express ectopic foxi1. Scale bar, 100 µm.
