On the other hand, it has previously been demonstrated that IL-8 is also linked to the mitosis and angiogenesis of cells [40–42] and that IL-8, GRO, and MCP-1 are produced by carcinoma cells in order to enhance the migratory functions of bone marrow-derived MSCs as a way in which cancer cells are able to support the chemotactic capacity of MSCs [43]. The gene discussed is CXCL8; the disease is cancer.
