      Abstract:

      Complete profiling would substantially facilitate the fundamental   understanding of tumor angiogenesis and of possible   anti-angiogenesis cancer treatments. We developed an integrated   synchrotron-based methodology with excellent performances:   detection of very small vessels by high spatial resolution (~ 1   μm) and nanoparticle contrast enhancement, in vivo dynamics   investigations with high temporal resolution (~ 1 ms), and   three-dimensional quantitative morphology parametrization by   computer tracing. The smallest (3-10 μm) microvessels were found   to constitute > 80% of the tumor vasculature and exhibit many   structural anomalies. Practical applications are presented,   including vessel microanalysis in xenografted tumors, monitoring   the effects of anti-angiogenetic agents and in vivo detection of   tumor vascular rheological properties.
