    Collapse Overview 
    Collapse overview
    The ultimate goal in our lab is to develop a tissue-engineered heart to treat patients of end-stage heart failure by replacing the diseased heart. As one of required steps, we are currently focusing on developing a tissue-engineered cardiac patch to promote in-situ myocardial regeneration and functional restoration.
