Supplementary Methods. Table S1: Primer/morpholino sequences used in this study. Figure S1: Knockdown efficiency and specificity of nr2f1b morpholinos. Figure S2: An increase in non-specific cell death after morpholino injection is not the cause of the observed vascular phenotype. Figure S3. Loss of nr2f1b results in pericardial edema, absent parachordal vessels, subintestinal vessels (SIV) mispattern and circulation defects. (DOC 2967 kb
