Research Description
My laboratory studies molecular and cellular mechanisms of cardiac tissue repair after myocardial infarction and in diabetic cardiomyopathy. At the cellular level, we investigate the role of endothelial and cardiovascular stem cells in tissue repair and regeneration. At the molecular level, we focus on the role of BMP signaling in inflammation after injury and in the growth and differentiation of various adult stem cell populations.
Research Keywords
Tissue repair and regeneration, pluripotent stem cells, heart, myocardial infarction, diabetic cardiomyopathy, BMP signaling, endothelial cells, genomics, mouse
