The tumor microenvironment is a complex system of various tumor cells, stromal cells, and immune cells. [1] The tumor microenvironment is a complex ecosystem surrounding a tumor, composed of cancer cells, stromal tissue (including blood vessels, immune cells, fibroblasts and signaling molecules) and the extracellular matrix.
