Fig. 1 . Induction of ectodermal markers at neural plate boundaries. Ectodermal marker expression in tailbud stage embryos (albino) that had received neural plate grafts (pigmented and/or mycGFP-labeled) into belly ectoderm at stage 13. (A-F′′) Grafts (arrows, outlined) are shown in overviews (A-F) and transverse sections in brightfield (A′-F′), green fluorescent channel (A′-F′), and overlay (A′′-F′′). Sox3 (A-A′′), Sox11 (B-B′′), Zic1 (C-C′′; inset shows higher magnification of expression in graft) and FoxD3 (D-D′′) are maintained or induced (asterisks) in graft. Six1 (F-F′′) is induced in host ectoderm (arrowheads), whereas Sox9 (E-E′′) is induced in the graft (asterisk) and sometimes in host ectoderm (arrowhead). |
