Figure 4. Stability of labeling and impact on pluripotency.

Figure 4

Differentiation (A–C) of labeled hMSCs and (D–F) unlabeled hMSCs. Images were obtained 3 weeks after particle labeling. Oil-Red-O staining for adipocytes (B, E) and von-Kossa staining for osteocytes (C, F). As shown in arrows in A and B, PB-PLL nanocomplexes were retained in the labeled cells even after 3 weeks of incubation. Scale bar is 100 µm.
