Adipose stroma cell-derived IL-6, oncostatin M (OSM), and C-C motif chemokine ligand 2 (CCL2) have been shown to promote breast cancer cell proliferation, migration and invasion (Walter et al., 2009; Arendt et al., 2013; Lapeire et al., 2014). The gene discussed is CCL2; the disease is breast carcinoma.
