Wenqing Cai is focusing on natural inducers of heart differentiation in embryonic stem cells. Heart attacks and congestive heart failure remain among most prominent health challenges in the world. However, despite successful approaches to prevent or limit cardiovascular disease, the restoration of function to the damaged heart remains a formidable challenge. Stem cell biology represents a new approach of regenerative medicine, and Wenqing is working toward using embryonic stem cells to replace damaged cardiomyocytes and restore cardiac function.
