Hatzopoulos Lab


The Hatzopoulos lab focuses on Molecular and Cellular mechanisms of cardiac repair and regeneration, emphasizing the role of wnt and BMP signaling pathways in angiogenesis and fibrosis after ischemic injury.  We also explore the potential of induced pluripotent (iPS) cells to differentiate to cardiomyocytes as a future strategy for cardiac tissue regeneration.
