Human Periodontal Ligament Stem Cell-Derived Exosomes Promote Bone Regeneration by Altering MicroRNA Profiles

<div>Internalization of exosomes by rBMSCs. PKH-26-labeled exosomes (red) were accumulated in the cytoplasm of rBMSCs after 6 h coincubation. The nuclei of rBMSCs were stained with DAPI (blue). The cytoplasm of rBMSCs was stained with CFDA-SE (green). Scale bar: 200 <i>μ</i>m.</div>
