Background-subtracted colour-coded CEU images reflecting retention fraction of αVβ3-targeted microbubbles in ischaemic proximal hindlimb adductor muscles from control untreated and FGF-
2-treated rats immediately after ligation (day 0) and at day 4 post-iliac artery ligation.

Schematic diagram of potential strategies for CEU-targeted imaging of stem/progenitor cells, such as EPCs. One strategy involves manipulation/transfection of EPCs to express a specific
marker protein on their surface.
