This review describes the current knowledge about cell subsets involved in
vasculogenesis (i.e., differentiation of endothelial cells from mesodermal
precursors) and angiogenesis (i.e., blood vessel generation from pre-existi
ng vessels), together with recent findings about angiogenesis and antiangio
genic therapies in hematopoietic malignancies such as leukemia, lymphoma, m
yeloma, and myelodysplastic syndromes. (C) 2000 International Society for E
