Fig. S9 The Arterial ProGramme is Unaffected by Targeted Knockdown of bmp4

a, b) gata1 expression in uninjected 10 somite stage embryos was normal within the posterior lateral mesoderm (PLM) (a), whereas bmp4 morphants demonstrate ectopic gata1 expression in the PLM, posterior to the tailbud (b) (red arrowhead). c-f) Expression of tbx20 within the DA was unaffected in control embryos or bmp4 morphants (red arrowhead). Ventral expression of tbx20 under the yolk cell extension was not lost in bmp4 morphants, presumably because other Bmp family members are important in its maintenance. g-j) Pan-arterial expression of deltaC was unaffected in control embryos or bmp4 morphants (red arrowhead).
