The tumor microenvironment plays an important role in several of the phenotypic traits of cancer. Hypoxia, in particular, leads to drug resistance, radiation resistance, and the selection of a more aggressive phenotype. The relationship between hypoxia, and the transport of macromolecules through the interstitial matrix in vivo is largely unexplored. The purpose of these studies was to determine if hypoxia alters the interstitial fluid transport of macromolecules by altering collagen fiber patterns.
