| Outline of Final Research Achievements |
We investigated the effect of cardiac stem cell (Cardiosphere-derived cells: CDCs) sheet using the hypoxic preconditioning (HPC) on the mouse old myocardial infarction model. The CDCs sheet was suggested to have a paracrine effect via the production of growth factors including VEGF. The paracrine effect resulted in an increase in angiogenesis in the border area of myocardial infarction.This effect also show the improvement of the wall motion of the mice hearts in echocardiography, and the reduction effect of the infarct region.
The effect of CDCs sheet treatment was enhanced by HPC. The HPC can easily activate the CDCs sheet function, suggesting the possibility that CDCs sheet treatment with HPC may be effective for ischemic heart disease.
