Figure 3. EC network formation in the EC and EC+EPC models.

Figure 3

After 5 days in culture, bright-field images indicate EC network formation in the EC (A) and EC+EPC models (D) with 10 ng/mL bFGF. Using these images, EC networks were marked in red (B, E) and skeletonized (C, F), and the length and number of the EC networks were measured. The EC+EPC model significantly increased both the length (G) and number (H) of EC networks compared to the EC model at days 3–5. Data are presented as the means ± SD (n = 27–51; *p < 0.05 vs. EC model). Scale bar, 300 μm.
