      Mechanical stress regulates tissue oxygenation, cancer cell proliferation and drug delivery during progression of solid tumors 

      Mpekris, F.; Angeli, S.; Pirentis, A. P.; Stylianopoulos, T. (Springer Verlag, 2016)
      Oxygen supply plays a central role in cancer cell proliferation. While vascular density increases at the early stages of carcinogenesis, mechanical solid stresses developed during growth compress tumor blood vessels and, ...
