Effectiveness evaluation of dendritic cell immunotherapy for osteosarcoma on survival rate and in vitro immune response

The aim of this study was to investigate the effects of dendritic cell (DC) therapy in osteosarcoma. Bone marrow DCs from Wistar (allograft group) and Sprague Dawley (SD) (homograft group) rats were electrically fused with the SD-derived osteosarcoma cell line UMR106 to generate a DC-osteosarcoma fusion (DOF) tumor vaccine, which was co-incubated with SD T lymphocytes to stimulate T cell proliferation. CD8+ and CD4+ cell percentages were measured by flow cytometry; tumor-cytotoxic effects of cytotoxic T lymphocytes (CTLs) were measured by the MTT assay.

Biological activity of cytotoxic dendritic cells cocultured with cytokine-induced killer cells and their effect on acute leukemia cells

X. Y. Cheng and Li, J. L., “Biological activity of cytotoxic dendritic cells cocultured with cytokine-induced killer cells and their effect on acute leukemia cells”, vol. 14, pp. 13208-13214, 2015.

We cocultured cytokine-induced killer (CIK) cells with dendritic cells (DCs) in vitro and investigated their proliferation, immunophenotype changes, secretory cytokine levels, and their antitumor effects on acute myeloid leukemia (AML) cells. DCs and CIK cells were acquired from healthy human peripheral blood mononuclear cells and cocultured as an experimental group, while CIK cells were cultured alone as a control group.
