Our long-term goal is to establish a cell coculture model with a defined microenvironment to systematically study the electromechanical coupling of adult stem cells with cardiac myocytes at the single-cell level. The objective for this project is to understand how bone marrow stem cells electrically couple with cardiac myocytes and how stem cell differentiation will affect this coupling. We will investigate the electrical coupling of bone marrow stem cells in an engineered cardiac myocyte-coculture model. In this model, identical cell-culture microwells will be fabricated to allow creation of a defined stem cell-myocyte interface in each well through application of a laser beam.
To test the hypothesis that the electrical coupling between stem cells and myocytes will be regulated by the spatial arrangements of cells and the temporal stages of stem cell differentiation, the following specific aims will be addressed:
Heart disease is America's leading cause of death for both men and women, accounting for nearly 40% of all annual deaths. By adding to the current knowledge of electrical coupling between bone marrow stem cells and heart muscle cells, our research will contribute to the recent effort in regenerative medicine to restore the function of a damaged heart using the patient's own cells. The significance of this research is that it provides an experimental model by which various stem cells are subjected to a highly controlled microenvironment during their functional differentiation. With application of the laser technique in this model, exact temporal and spatial constraints on electrical coupling and integration between stem cells and myocytes can be investigated. The results of this research will significantly advance our fundamental knowledge of the functional integration between stem cells and myocytes.
In addition to 50% release time, Clemson will provide more than 2,500 sq ft of lab space and unlimited access to all Core facilities, which are staffed and provide with state-of-the-art equipment.
