| Outline of Final Research Achievements |
In recent years, it has been pointed out the possibility of “aging” in elderly patients-derived cardiac stem cells, leading to take measures against stem cell therapy for elderly patients with severe heart failure. In this study, we aimed to clarify the correlation of stem cell aging with patient’s age and to develop novel strategies to induce rejuvenation of “aged” cardiac stem cells using 26 patients-derived cardiac stem cells isolated from 2-83 years old. As a result, however, “aging” in elderly patients-derived cardiac stem cells was quite limited, meaning that it is not necessary to induce rejuvenation of elderly patient-derived cardiac stem cells. This encouraged us to use elderly patient-derived cardiac stem cells in cell-based therapy for elderly patients with severe heart failure.
