MDSC activity in cancer promotion. Different subsets of MDSCs are recruited to the tumour microenvironment and promote tumour progression in several ways: (1) they sustain tumour cell stemness by acting directly on tumour cells (upper panel on the right); (2) they promote blood vessel formation through the secretion of pro‐angiogenetic factors (central panel on the right); (3) they support EMT to enhance metastatic potential (lower panel on the right). HCF, hepatocyte growth factor; MET, epithelial‐mesenchymal transition.
