FIG. 7.

Endothelial barrier function assay. (A–C) Representative images of lumens within control constructs at days 8 (A) and 11 (B), and constructs exposed to low flow for 3 days (from day 8 to 11; C). Scale bar=10 μm. (D–F) Enlarged portions of the lumens showing in (A–C), for easier visualization of the gold nanoparticles (GNP). (G) Quantification of the GNP present within the lumens (mean±SEM); low levels of GNP within lumens of constructs exposed to low flow indicated strong EC barrier function. *p<0.05.
