Expert Details

Building Vascular Networks, Vascular Tumors, Endothelial Plasticity in Heart Valves

ID: 730062 Massachusetts, USA

Request Expert

Expert's expertise is centered on angiogenesis and endothelial cells – the cells that comprise the endothelium of blood vessels and the heart, and how these cells become disrupted in disease. Her laboratory is also investigating how to use normal healthy endothelial and mesenchymal cells to build new vascular networks for regenerative medicine and tissue engineering. Specific areas described below:

Area I: Cellular and molecular basis of hemangioma – a vascular tumor of infancy and other types of vascular anomalies.

Hemangioma is a tumor of endothelial cells that occurs in infants. These tumors can grow rapidly, cause organ damage and disfigurement and even threaten life. Expert's laboratory is elucidating the cellular and molecular mechanisms that drive this uncontrolled growth. She has identified a hemangioma stem cell that forms all of the major cellular constituents of this vascular tumor – endothelial cells, pericytes and adipocytes. Her ultimate goal is to translate our basic research on hemangioma-derived stem cells and endothelial cells to develop safe fast-acting therapies that will stop hemangiomas from growing to a life-threatening or endangering size.

Area II: Using Blood-derived Endothelial Progenitors for Tissue Vascularization

Expert's goal is to build new vascular networks from human endothelial and mesenchymal progenitor cells to re-build damaged tissues and organs. She has shown that such cells can be obtained from human peripheral blood or bone marrow, expanded in the laboratory without difficulty, and used to build functional blood vessels in vivo in murine models. In the future, she envisions the use of a patient’s own endothelial and mesenchymal progenitor cells to build vascular networks for tissue-engineering applications and for in situ regeneration of vascular networks in ischemic tissue.

Area III: Plasticity of Cardiac Valvular Endothelium

Expert's laboratory has studied growth and differentiation of normal cardiac valvular endothelial cells for several years. Their studies have shown that valvular endothelial cells from adult valve cusps or leaflets can recapitulate processes that occur during valve development. These pathways involve transforming growth factor-ß and vascular endothelial growth factor (VEGF) signaling. Their recently published study indicates that the valvular endothelium harbors progenitor cells with endothelial/mesenchymal plasticity. They are studying this role of this inherent plasticity in the context of heart valve disease.
