Magnetically labeled mesenchymal stem cells after autologous transplantation into acutely injured liver

Figure 1 Characterization of labeled mesenchymal stem cells. A: Almost 100% of labeled mesenchymal stem cells (MSCs) were positive for Prussian blue staining (magnification 100 ×); B: No blue particles were observed in unlabeled group (magnification 100 ×); C-E: Prussian blue staining for liver tissue slicing displayed several blue-positive cells scattering in and around sinusoids on day 3 and 7, and the experimental group at the endpoint of the experiment (magnification 100 ×). Arrows indicate Prussian blue positive MSCs.
