title: Blood and lymph vessels in embryonic tumors.
abstract: Formation of embryonic blood and lymph vessels is mediated by different steps of vasculogenesis and angiogenesis. The vascular endothelial growth factor family (VEGF) as well as the VEGF-receptors on the surface of blood endothelial cells and lymph endothelial cells are responsible for both processes. In addition to the embryonic development of the vessel systems, the interactions of angiogenesis factors and receptors are also present in solid tumors. Embryonic tumors in children offer an interesting target for new substances developed for anti-angiogenesis. Some data on the role of blood vessels and anti-blood-angiogenesis are available on embryonic tumors. However, studies of lymph-angiogenesis are not found and anti-lymph-angiogenesis is not at all examined in embryonic tumors. This review gives an overview of the challenging field of angiogenesis and anti-angiogenesis of both blood and lymph vessels with a focus on embryonic tumors.
