Figure 8

Confocal images of beads accumulated on the HUVEC layers. (A) Accumulated beads (green) on the normal HUVEC layer (non-treatment group). (B) Accumulated beads (green) on the abnormal HUVEC layer (treatment group). The images were captured after 1 min under a flow rate of 1 mL/h (shear stress: 23.96 mPa). White arrows indicate the direction of medium flow, and red arrows in (B) denote the bead clusters accumulated near the HUVEC clusters. The cross-sectional profiles are displayed along the yellow lines in the right ends and bottom parts. Scale bar = 100 μm.
