Background: Vascular endothelial cadherin (VE-cadherin/cadherin-5) has previously been described as playing a specific role in angiogenesis due to its localisation at areas of intercellular contact, where it functions in maintenance of tubular architecture. Matrix-bound fibroblasts have been show to produce a number of factors that are important in inducing angiogenesis and to promote tubule-formation by human endothelial cells, an indicator of angiogenic potential.
Results: Tubule formation stimulated by fibroblast-derived growth factors can be prevented by the addition of monoclonal antibody to VE-cadherin. In addition, fibroblasts-derived growth factors are able to modulate the expression and hence the regulation of this endothelial cell specific cadherin.
Conclusions: The change in VE-cadherin expression of human endothelial cells by fibroblast-derived growth factors may contribute to the regulation of angiogenesis.
