Fig. S4 Identity of FoxA2–FoxA3 morphant cells located in the ventral neural tube. Dorsal marginal cells labeled with GFP and depleted of FoxA2 and FoxA3 activities give rise to cells located in the ventral neural tube at 24 hpf in a FoxA2–FoxA3 morphant (A–D) and in a wild-type embryo (E–H). Identity of labeled cells determined by double labeling of GFP (B and F) with the floor plate markers spondin1a (C) or foxA2 (G). GFP-labeled cells never express the floor plate markers (D and H). Squares in A and E indicate the region magnified in B–D and F–H, respectively. Lateral views, anterior to the left.
