Exosomes Derived from Magnetically Actuated Bone Mesenchymal Stem Cells Promote Tendon-Bone Healing through the miR-21-5p/SMAD7 Pathway

Investigators isolated and characterized the two types of exosomes, conducted in vitro experiments to measure their effects on fibroblasts (NIH3T3), and performed in vivo experiments to compare the effects on tendon-to-bone integration.
