Public Abstract: 

For the millions of Americans who are born with or develop heart disease, stem cell research offers the first hope of reversing or repairing heart muscle damage. Thus, early reports suggesting heart regeneration after transplantation of adult bone marrow-derived stem cells were met with great excitement in both the scientific and lay community. However, although adult stem cell transplantation was shown to be safe, results from over a dozen clinical trials concluded that the benefits were modest at best and whether any true regeneration is occurring was questionable. The basis for these disappointing results may be related to poorly characterized cell types used that have little capacity for true regeneration and an inadequate understanding the factors necessary for survival and differentiation of transplanted stem cells. In this application, we are proposing to develop a cardiac cell therapy using cardiac progenitor cell, which is isolated from human induced pluripotent cells that can differentiate into cardiac muscle cells, smooth muscle cells and endothelial cells. We will develop the techniques and models that will allow the preclinical testing of this progenitor cell, which is required by the FDA to move to clinical trials. This knowledge will be applied to future clinical trials of cardiovascular cell therapy that allow truly regenerative therapy.

Statement of Benefit to California: 

Heart disease, stroke and other cardiovascular diseases are the #1 killer in California. Despite medical advances, heart disease remains a leading cause of disability and death. Recent estimates of its cost to the U.S. healthcare system amounts to almost $300 billion dollars. Although current therapies slow the progression of heart disease, there are few, if any options, to reverse or repair damage. Thus, regenerative therapies that restore normal heart function would have an enormous societal and financial impact not only on Californians, but the U.S. more generally. The research that is proposed in this application could lead to new therapies that would restore heart function after and heart attack and prevent the development of heart failure and death. We will develop the techniques and models that will allow the testing of this progenitor cell as required by the FDA to move to clinical trials.
