Promoting Osteogenic Differentiation of Human Adipose-Derived Stem Cells by Altering the Expression of Exosomal miRNA

Figure 3

Internalization of exosomes by ADSCs. ADSCs can ingest a large number of exosomes at only 6 h postincubation. The results shown in Figure S1 further confirmed that exosomes can be internalized by ADSCs. Exosomes were labeled with Dil (red), and the nuclei were stained with Hoechst33258 (blue). Scale bar: 100 μm.
