Papers from an April 2002 workshop address new developments in angiogenesis research, looking at current priorities in the research of circulating pre-endothelial cells, cross talk between hematopoiesis and angiogenesis, and the contribution of adult hematopoiesis stem cells to retinal neovascularization. Other topics include phenotypic overlap between monocytes and vascular endothelial cells, circulating endothelial cells as a novel marker of angiogenesis, and tissular insemination of progenitor endothelial cells.
