Engineering the Heart in a Dish

Our research involves the study of functional properties of engineered networks of living cardiac cells at varying structural levels that include single cells, cell strands, 2D sheets, and 3D tissue. We culture neonatal rat ventricular cells, human embyonic stem cell-derived cardiomyocytes and human induced pluripotent stem cell-derived cardiomyocytes as multicellular networks to investigate fundamental properties of action potential propagation and arrhythmias. The use of voltage-sensitive dyes and optical mapping allows us to follow the temporal and spatial patterns of electrical activity.

Our work is currently directed within the following areas:

  • Functional properties of cardiomyocytes derived from human pluripotent stem cells
  • Engineered cardiac tissues
  • High frequency alternating current for cardiac therapy
  • Myofibroblast-cardiomyocyte interactions More details are available on our lab website.
