Evaluating tumor angiogenesis.
The evaluation of tumor angiogenesis in pancreatic cancers involves determining the status of tumor vasculature and hypoxia in the tumor. Describing the nature and extent of tumor angiogenesis involves evaluating the expression of endothelial and perivascular cells within the tumor, and the expression of angiogenesis-related genes in tumor vasculature. Here we describe the methodology for assessment of tumor vasculature in murine mouse models of cancer. Specifically, we provide methodology for the evaluation of tumor hypoxia, tumor vessel perfusion, and chromogenic and fluorescent immunohistochemistry applied to tumor vascular analysis.
