| Outline of Final Research Achievements |
Recently, it was found that cells release various types of cell-derived particles such as vesicles known as exosomes. In this study, cell-derived particles with long retention time in blood was explored by evaluating blood circulation half-life of cell-derived particle samples prepared by separation using various methods. As a result, cell-derived particles with long retention time in blood was found.
