Figure 5From: Angiogenic potential of endothelial progenitor cells and embryonic stem cellsCharacterization of differentiating ESCs at D7. Tubule formation as (A) node number ± SEM (n = 3) and (B) tubule branch length ± SEM (n = 3; *P < 0.05, **P < 0.01 vs. 2 h). (C) VEGFR2, (D) VE-cadherin and (E) CD31 mean expression in D7 ESCs (n = 3) relative to 60% confluent ECs; *P < 0.05, **P < 0.01 vs. 0 h. Dotted line indicates expression in 60% confluent EPCs.Back to article page
