CCL3 and neoplasm: Multiplex analysis of murine cytokines and growth factors revealed an increased level of murine angiogenic factors VEGF, bFGF, as well as MIP-1α and MCP-1 in CSCs-derived tumors in comparison to parental H460 tumors growing in SCID mice, indicating that CSCs more efficiently stimulate murine proangiogenic factors and blood vessel formation to support the growth of xenografted human tumor.
