Exosomes Derived from Stem Cells from the Apical Papilla Promote Dentine-Pulp Complex Regeneration by Inducing Specific Dentinogenesis

Figure 3

Exosomes from the stem cells of the apical papilla (SCAP-Exo) were endocytosed by bone marrow mesenchymal stem cells (BMMSCs). PKH-26-labelled SCAP-Exo (red) was internalised into the cytoplasm of DAPI-labelled BMMSCs (blue). In the negative control group of BMMSCs without exosomes, only the nuclei of BMMSCs were stained with DAPI (blue).
