Abstract
Angiogenesis is a complex sequential process involving endothelial activation, basement membrane degradation, endothelial sprouting from the parent vessel, invasion of the extracellular matrix, endothelial proliferation, vessel elongation, branching, anastomosis, increases in vessel diameter, basement membrane formation, pericyte acquisition, and remodelling. Most in vitro angiogenesis assays are two-dimensional and measure only one facet of this process, generally endothelial proliferation, migration, or tube formation. The two-dimensional nature of the assays also ignores the differences in endothelial phenotype seen in three-dimensional models and in vivo. The in vitro serum-free three-dimensional rat aortic model closely approximates the complexities of angiogenesis in vivo, from endothelial activation to pericyte acquisition and remodelling, and most of these can be quantified by image analysis, immunohistochemistry, and biochemical analysis. It is easily manipulated using molecular biological intervention or exogenous inhibitors and activators in a relatively controlled system.
