This study evaluated the role of exosomes isolated from mesenchymal stem cell (MSC)‐conditioned medium (CM) in the fracture‐healing process of CD9 −/− mice, which produce reduced levels of exosomes. Retardation of fracture healing in CD9 −/− mice was rescued by the injection of MSC exosomes, but not exosome‐free CM, showing that MSC exosomes are a novel factor of MSC paracrine signaling, with an important role in the tissue repair process.
