Figure 5


Fig. 5. The effects of FoxF:WRPW on GATA-a and NK-4 expression are variable. Embryos electroporated with Mesp>lacZ and the indicated constructs (left) were stained for ß-galactosidase (red) and either GATA-a (A,C,E) or NK-4 (B,D,F) mRNAs (green). (A,B) Wild-type embryos. (C-F) Embryos electroporated with Mesp>FoxF:WRPW. GATA-a and NK-4 expression persists (C,D) or is abolished (E,F) in non-migrating trunk ventral cells (TVCs). Arrowheads indicate anterior B7.5 cells.
