Bead accumulation on HUVECs cultured on the two collagen films. Fluorescent images of accumulated beads (green) on the normal (A and B) and abnormal HUVEC (red) layers (C and D). The images were captured after 1 min under a flow rate of 1 mL/h (shear stress: 23.96 mPa). The images in the yellow dotted box were magnified two times (B and D). Scale bar: 100 μm. (E and F) Temporal variations in the number of clusters (E) and sum of cluster areas (F).
