Another group analyzed the effects of human adipocyte stem cells (hASC), mature and immature adipocytes co-cultured with BC cells, and reported an increase in the release of proinflammatory cytokines IL6, IL8, IFNγ-IP10, C-C Motif Chemokine Ligand 2 (CCL2) and CCL5 by BC cells, especially after interaction with immature adipocytes. The gene discussed is CCL5; the disease is breast cancer.
