Research interests

We pursue to unravel some molecular aspects of early mammalian cardiomyogenesis.We are interested in signaling and genetic regulation of commitment and differentiation of cardiac stem cells and the transcriptional balancing of self-renewal and differentiation in adult cardiac stem cells.
