In this study, we enhanced the maturity of myofibril organization in stem cell-differentiated cardiomyocytes with microfabrication approaches and investigated the mechanisms that drive structural maturation.

Here we found that epicardial cells contain a potent cardiogenic activity identified as follistatin-like 1 (Fstl1). Application of the human Fstl1 protein via an epicardial patch stimulates cell cycle entry and division of pre-existing cardiomyocytes, improving cardiac function and survival in mouse and swine models of myocardial infarction.

Published in Cell Stem Cell: 17, 89–100


This is the first study that systematically characterized β-adrenergic signaling maturation in iPSC-CMs, which has set a baseline for all the studies focusing on beta signaling mechanism and beta-blocker drug screening in iPSC-CM models.  In this paper, we have identified the up-regulation of key molecular events during the pathogenesis of familial DCM, subtype-specific blockade.

Published in J Am Coll Cardiol. 2016;67(14)


In this paper, we investigated the prognostic value of the residual angiographic coronary artery stenoses after FFR-guided "functionally" complete revascularization.  We found that after "functionally" complete revascularization with FFR guidance, the residual angiographic lesions do not reflect residual ischemia or predict a worse outcome.
