Fig. 2From: Single- and double-walled carbon nanotubes enhance atherosclerogenesis by promoting monocyte adhesion to endothelial cells and endothelial progenitor cell dysfunctionEffects of SWCNTs and DWCNTs on cell viability. Cell viability was measured by cell viability assay kit. HAECs were exposed to CNTs at concentrations ranging from 0.1 to 20 μg/ml for 16 h. Data are mean ± SD. (n = 8, *p < 0.05 vs. control; CTL) HAEC: normal human aortic endothelial cell, SWCNT: single-walled carbon nanotube, DWCNT: double-walled carbon nanotubeBack to article page
