Normalizing the tumor microenvironment Normalizing the tumor microenvironment Excess angiogenic molecules produced by cancer or stromal cells cause abnormal tumor vasculature. ECM-normalizing drugs can decompress the blood vessels, and anti-angiogenesis therapies can reverse many of the TME abnormalities, resulting in improved perfusion and immune cell infiltration and creation of an immunostimulatory microenvironment.
