Current Perspectives on In Vivo Noninvasive Tracking of Extracellular Vesicles with Molecular Imaging

Figure 3

In vivo noninvasive visualization of fluorescent dye labeled EVs in nude mice. Representative in vivo fluorescent imaging of EV-DiR or PBS (control) was administered via the tail vein in nude mice. Images were acquired at 30, 60, and 120 min after injection. EV, extracellular vesicle.
