Cardiovascular Development and Disease


Fluid forces and ligand-receptor interactions regulate the development of the heart, blood, and lymphatic vessels and its function after development.

We have studied the role of flow-responsive signals KLF2 and KLF4 in heart development (Dev Cell 2015 and 2017) in addition to the secreted ligands ADAMTS3 and CCBE1 in VEGF-C/VEGFR3 signaling (Blood 2013) during lymphatic development and hematopoiesis. Recent work aims to integrate the role of blood flow and KLF2/4 in postnatal heart disease and the role of VEGF-C/VEGFR3 signaling in the growth of other vascular beds in the context of developmental hematopoiesis.
