Endothelial cell density on UniChip, BiChip or in static culture. HUVECs were seeded onto cell inserts at a same density for all groups. UniChips and BiChips were assembled 24 h later and operated for 5 days. Cells from 10 representative views (567μm × 567μm) for each group were then counted based on nuclear staining. Cells in all groups were confluent, yet those on UniChips showed significantly lower density than cells on BiChips or in static culture. Data are presented as mean ± SD. Significance by one-way ANOVA with Tukey's multiple comparisons test; **** p <0.0001; ns, not significant.
