The "Angiogenesis Analyzer"  allows analysis of cellular networks. Typically, it can detect and analyze the pseudo vascular organization of endothelial cells cultured in gel medium
Among the tools used to evaluate the anti-angiogenesis properties of drugs, the most used is the in vitro differentiation of primary endothelial cells culture in gel (Endothelial Tube Formation Assay (ETFA)) . In suitable culture conditions these cells form structures that can branch and mimic a pseudo capillary in vitro formation. At later stage this differentiation can lead to a meshed network from different mesh sizes. Although widely used, the interpretation of this assay still remains a problem, especially to obtain a quantitative evaluation of the vessels-like net organization. The Angiogenesis Analyzer is a simple tool to quantify the ETFA experiment images by extracting characteristic information of the network.
