Extended Data Figure 7. Low-power electron micrograph images of LDL-gold and immunogold-labeled SR-B1 in aortic endothelial cells in vivo.
Following intravascular administration in wild-type mice, gold-labeled LDL particles and SR-B1 were localized in aortic endothelial cells by electron microscopy. a and b display images for two different endothelial cells, each bordered by the lumen and elastic lamina. Shown are the locations of the high-power fields provided in Figure 1n, with LDL-gold (large particles) highlighted by yellow arrows and immunogold-labeled SR-B1 (small particles) highlighted by red arrows.
