FIG. 6.

(a) Mean nucleus thickness of HUVECs under indicated culture conditions: datasets for conditions (i) and (ii) are not statistically different (**, $p>0.05$), while datasets for conditions (iii) and (iv) exhibit a statistically significant increase compared to condition (i) (*, $p<0.05$). (b) 3D reconstructions of the bottom part of a channel showing cells lying in the corners under 0.4 Pa (top image), while they tend to detach from corners and round up the effective lumen under 0.08 Pa (bottom image). The lateral channel size is $30\mu \mathrm{m}$.
