To further analyze the cytokine profiles in the hUC-MSCs pre-treated with IL-6, the luminex analysis system was used to determine the content of several inflammation- and cancer-related cytokines in the cell culture supernatant, which included G-SCF, IL-10, PDGF-BB, IL-6, IL-8, MCP-1, TNFα and VEGF. This evidence concerns the gene TNF and cancer.
