Figure EV3. Proliferation of IAHCs and endothelial cells is not changed upon αDll4 treatment.

BrdU incorporation assay upon IgG or αDll4 treatment in Kit⁺ (A, B) and CD31⁺ endothelial cells (C, D).

• A, C
  Representative confocal images of transversal sections in the AGM region. Autofluorescent circulating cells are signed by asterisks. Scale bar: 30 μm.
• B, D
  Bars represent the percentage of Kit⁺ or CD31⁺ cells that incorporated BrdU. Mean ± SE (n = 3).
