The rescue of ephrinb2a but not runx1 or c-myb expression by scl-α in etsrp morphants is abolished by SU5416 treatment. (A-L) runx1, c-myb, and ephrinb2a expression in control (0.2% DMSO; A,E,I), etsrp MO (0.2% DMSO; B,F,J), etsrp MO + scl-α mRNA (0.2% DMSO; C,G,K), and etsrp MO + scl-α mRNA (2μM SU5416; D,H,L). (A-D) runx1 expression in the ventral wall of the DA (arrowheads) at 30 hpf. (E-H) c-myb expression in the ventral wall of the DA (arrowheads) at 40 hpf. (I-L) ephrinb2a expression in the DA (arrowheads) at 30 hpf.
