Figure 5. IONPs internalization by CMI is applicable to hMSCs.
(A) Optical microscopy images of hMSCs cells after Prussian blue staining following IONPs internalization (50–75 μg/ml) by CMI at 1000 rpm and different CF-application time (1, 5, 10 and 15 minutes); (B) Labelling efficiency of hMSCs with IONPs internalized by CMI in all different sceneries. Scale bar: 40 μm, in the main images, and 10 μm, in the inserts.
