Fig. 9

foxc1 acts upstream of acta2 in vSMC differentiation. A-D) Ablation of foxc1b and acta2 positive cells using Metronidazole (MTZ) from 3 to 4 dpf. Embryos are heterozygous for foxc1b- or acta2:Gal4 and UAS:NTR-mCherry. Ventral views show smooth muscle coverage along the ventral aorta in controls (A and C), but largely absent in MTZ treated embryos (B, D). E-F) Ventral views of mural cell marker mRNA (acta2 and pdgfrβ) in foxc1b:Gal4; UAS:NTR-mCherry embryos show a reduction in acta2 and increase in pdgfrβ in MTZ treated embryos (F) versus controls (E). G-H) Expression of acta2 is reduced in MTZ treated acta2:Gal4; UAS:NTR-mCherryembryos versus controls, while pdgfrβ expression is unchanged. I-L) Expression of foxc1b mRNA is reduced in MTZ treated foxc1b:Gal4; UAS:NTR-mCherry embryos compared to controls, while foxc1bmRNA is unchanged in controls and MTZ treated acta2:Gal4; UAS:NTR-mCherry embryos. Green hearts in A-H are due to the transgenesis marker (myl7:EGFP). Scale bar represents 50 μm.
