Figure 2

Visualization of m/z 409.3 (LPA 16:0) in aortic roots of ldlr–/– mice and apoe–/– mice in negative ion mode. On the left, the MALDI mass spectrometry imaging visualization of LPA 16:0 is shown for 55 different tissue sections of 11 ldlr–/– mice, and on the right for 20 different tissue sections of 4 apoe–/– mice, showing specific plaque localization in all aortas. Magnifications of two representative tissue sections are depicted on the lower right together with their coregistered, hematoxylin and eosin (H&E)-stained images (plaque circumferences are indicated in yellow).
