Indeed, conditioned media from mesenchymal‐like breast cancer cell lines activate macrophages into a TAM‐like phenotype, including high expression of CD206 (a scavenger receptor also known as macrophage mannose receptor or MMR) and high secretion of CCL17, CCL18, CCL22, and IL‐10 (Su et al., 2014). Here, CCL18 is linked to breast cancer.
