Dr. Fishman's laboratory is interested in understanding the development, function and pathophysiology of the heart's specialized conduction system (CCS).  Toward that end, using transcriptional profiling we have recently identified a novel cell surface protein that appears to be uniquely expressed by cells contributing to the CCS network. The transcriptional circuitry that regulates the specification of these cells and mechanisms that regulate their organization into a functional network are being explored.  In a related series of studies, we have established murine embryonic stem cells that harbor an alternative CCS-specific marker.  We are using these cells to characterize the differentiation of ES cells into functional conduction system cells. Together, these approaches may provide additional insight into CCS biology and novel therapies for conduction system and arrhythmic diseases.
