Nanoparticle Labeling of Bone Marrow-Derived Rat Mesenchymal Stem Cells: Their Use in Differentiation and Tracking

Figure 4

In vivo tracking of CPN-MSCs. Paraffin embedded liver tissues obtained from rats that were injected with either CPN-labeled ((a)–(f)) or nonlabeled MSCs ((g)–(i)) from tail vein followed by PH ((a)–(c) and (g)–(i)) and SH ((d)–(f)). White arrows denote injected CPN-labelled MSCs under FITC filter. Magnification bar: 10 μm.
