| Research Abstract |
Exosomes are membrane vesicles which contain protein, lipids, mRNA, and miRNA. It has been reported that exosomes are secreted from stem cells. However, the role of exosomes in tissue regeneration is not elucidated.
In this study we found that exosomes derived from mesenchymal stem cells (MSC-exo) being taken in by cells, and promoted angiogenesis and cell differentiation, and also that periodontal regeneration caused by the MSC culture supernatant was depend on MSC-exo. Although regenerative therapy using stem cells has been considerable promise in preclinical studies, there are several issues to be solved such as tumorigenesis of transplanted stem cells. Our findings indicate the possibility of novel regenerative therapy without cell transplantation.
