| Outline of Final Research Achievements |
Mesenchymal stem cells (MSCs) can differentiate into various cells and have the potential of therapeutic agents. Exosomes are nano-sized vesicles released from cells and play an important role in cellular communication. Recent studies showed that exosomes from MSCs are considered as a substitution of cell-based therapy. In this study, we collected exosomes from MSCs or osteogenic MSCs and compared their functions. In addition, exosome-like vesicles known as matrix vesicles, released by osteoblasts to induce mineralization, were isolated from osteogenic MSCs. We found the different biological functions between exosomes and matrix vesicles, and glycan profiles of exosomes reflect the biogenesis and cell differentiation.
