S100 chemokines mediate bookmarking of premetastatic niches

Primary tumours release soluble factors, including VEGF-A, TGFbeta and TNFalpha, which induce expression of the chemokines S100A8 and S100A9 in the myeloid and endothelial cells within the lung before tumour metastasis. These chemokine-activated premetastatic niches support adhesion and invasion of disseminating malignant cells, thereby establishing a fertile habitat for metastatic tumours.
