Abstract
Targeting neoangiogenesis is a wellβestablished anticancer strategy, however, one of the major problems in angiogenesis research, both at the basic and applied levels, remains the development of suitable in vivo methods for assessing and quantifying the systemic angiogenic response. Therefore, there is an urgent need to adopt technically simple and reproducible methodologies which allow to easily quantify neoangiogenesis independently of morphological parameters. Recently, a reproducible and quantitative method was developed, the directed in vivo angiogenesis assay (DIVAA) consisting of the subcutaneous implantation of surgical grade silicone cylinders closed at one end, called angioreactors, into the dorsal flanks of nude mice. In the past few years, DIVAA has been successfully used in evaluating the inhibition and or enhancement of systemic perturbation of angiogenesis by several molecules. Thus, DIVAA studies systemic angiogenesis and its therapeutic modulation associated to cancer progression and metastasis.

We describe a quantitative assay for assessing tumor angiogenesis in vivo using basement membrane extracts (Matrigel). Nude mice were injected S.C. with liquid Matrigel mixed with HT I080 human fibrosarcoma cells. Since Matrigel rapidly forms a solid gel at body temperature, the gel containing tumor
