The concept that cell signalling is topologically restricted and vectorially orientated has stimulated much work. Restriction has been explained by the identification of signalling protein complexes in membrane microdomains (rafts and caveolae). The participation of endothelial cell caveolae to angiogenesis has been well reported and a distinction between normal and tumour-induced angiogenesis has been clearly documented. These advancements in the comprehension of signal transduction events preceding or concomitant to the angiogenic process required dramatic advancements in the methodology employed. We will describe the main techniques employed to evaluate the connection of endothelial cell signal transduction to angiogenesis, focusing on their strength and limitations.
