Vascular Biology & Cancer Microenvironment

We study the role of blood vessels, and of endothelial cells, in regulating normal organ function and in disease. In detail, we study cancer (solid and hematologic) as a systemic disease that involves (and requires) blood vessels for its onset and progression. In addition to the role of blood vessels, we also study the involvement of bone marrow-derived cells and of metabolic systemic signals in cancer onset and progression.
