Fig. 3From: Efficient differentiation of human embryonic stem cells to arterial and venous endothelial cells under feeder- and serum-free conditionsFlow cytometry analysis of induction of H1-hESCs towards endothelial lineage. Representative flow cytometry overlays display the kinetics of co-expression of vascular endothelial growth factor receptor-2 (VEGFR2) and CD34 (a), and CD31 and CD34 (b) upon induction of H1-hESCs with BMP4 (Gi.F.B), VEGF (Gi.F.V) and BMP4 + VEGF (Gi.F.BV) over a differentiation period of 5 daysBack to article page
