Abstract

Investigations carried out over the past 3 years have implicated a key role for sphingosine 1-phosphate (SPP) in angiogenesis and blood vessel maturation. SPP is capable of inducing almost every aspect of angiogenesis and vessel maturation in vitro, including endothelial cell chemotaxis, survival, proliferation, capillary morphogenesis and adherence antigen deployment, as well as stabilizing developing endothelial cell monolayers and recruitment of smooth muscle cells to maturing vessels. Acting in conjunction with protein angiogenic factors, SPP induces prolific vascular development in many established models of angiogenesis in vivo. Thus, SPP is a unique, potent and multifaceted angiogenic agent. While SPP induces angiogenic effects by ligating members of the endothelial differentiation gene (EDG) G-protein-coupled family of receptors, recent studies suggest that endogenously produced SPP may also account for the ability of tyrosine kinase receptors to induce cell migration. Thus, SPP provides a clear link between tyrosine kinase and G-protein-coupled receptor agonists involved in the angiogenic response. However, the mechanisms by which SPP exerts its effects on vascular cells remain unclear, conflicting and controversial. Precise definition of the signalling pathways by which SPP induces specific aspects of the angiogenic response promises to lead to new and effective therapeutic approaches to regulate angiogenesis at sites of tissue damage, neoplastic transformation and inflammation. This review will trace the discovery of SPP as a novel angiogenic factor as it outlines present information on the signalling pathways by which SPP induces its effects on cells of the developing vascular bed.
