For example, lymphoma-associated MSCs can trigger the recruitment of neutrophils, monocytes, and macrophages to the TME through the release of high amounts of chemokine (C-C motif) ligand-2 (CCL2), CCL7, and CCL12, all of which are ligands of the CCR2 receptor that mediates chemotaxis and migration processes. Here, CCL2 is linked to lymphoma.
