Figure 2. Localization of matrix metalloproteinase activity in three carotid specimens.

Figure 2

Samples 1 and 2 were incubated in MMPsense™ 680, a fluorescent probe activated by matrix metalloproteinase, while sample 3 (control) was incubated in PBS. (A–C) Imaging results from intact plaques made with MSOT. Cross-sectional multispectral reconstruction, revealing the location of MMPSense680 activity in the slice, is shown by the bright signal (green color online) that is superimposed onto the morphological single-wavelength (635 nm) optoacoustic images. (D–F) The corresponding epifluorescence images from dissected plaque (in green online) superimposed onto the color images of cryosections from the three carotid plaque specimens.
