Advances in Molecular Imaging Strategies for In Vivo Tracking of Immune Cells

Figure 3

In vivo tracking of peritoneal macrophage migration toward CG-induced inflammatory lesion by MRI. Peritoneal macrophages were isolated from C57BL/6 mice at day 4 after injection with 3% thioglycollate medium and then labeled with magnetic nanoparticles. MRI was obtained before or after injection of 1% carrageenan by 4.7T MRI. Arrow indicates hypointense signal of migrated peritoneal macrophages.
