tissue-specific differentiation of pluripotent stem cells , functional engraftment in regenerative cell replacement


My laboratory is broadly interested in cardiac development and stem cell biology. To study cardiomyocytes in health and disease, we generate stem cell models or transgenic mice by introducing reporter genes or mutations into the DNA of pluripotent stem cells. Using these models, we optimize the properties of cardiomyocytes derived from pluripotent stem cells for their useful application in pharmacological, personalized medicine and regenerative medicine approaches. In more detail, my research interests are

1) to advance methods to specifically generate cardiomyocyte subtypes,

2) to improve the electro-mechanical maturity of in vitro differentiated cardiomyocytes, and

3) to use stem cell-derived cardiomyocytes to investigate the pathogenesis and progression of cardiovascular disease.
