| Outline of Final Research Achievements |
Very recently, we identified circulating mesoangioblasts (cMABs), a subset of mesenchymal stem cells that co-express cardiac mesodermal markers from the patients undergoing cardiac catheterization. Here, we explored #1: where cMABs come from and #2: how we can induce cardiac differentiation of cMAB efficiently.
#1. Fist, we examined patients undergoing cardiac catheterization. We simultaneously obtained blood samples from aortic sinus (Ao), coronary sinus (CS: drain of the blood perfusing heart) and right atrium (RA) and compared the number of obtained cMAB colonies among those three different points. We confirmed that the heart is predominant niche of human cMABs. For further confirmation, we planed 2 clinical and 1 experimental studies. However, these studies were stopped by unexpected situations. #2. We tested several medium and matrix. Finally cells (MABs) were quite similar to iPSCs after induction of cardiac differentiation, however we could not see beating MABs.
