A simple in vitro method for evaluating dendritic cell-based vaccinations.

ABSTRACT:

Background

Dendritic cell (DC) therapy is a promising therapy for cancer-targeting treatments. Recently, DCs have been used for treatment of some cancers. We aimed to develop an in vitro assay to evaluate DC therapy in cancer treatment using a breast cancer model.

Methods

DCs were induced from murine bone marrow mononuclear cells in Roswell Park Memorial Institute (RPMI) 1640 medium supplemented with GM-CSF (20 ng/mL) and IL-4 (20 ng/mL). Immature DCs were primed with breast cancer stem cell (BCSC)-derived antigens. BCSCs were sorted from 4T1 cell lines based on aldehyde dehydrogenase expression. A mixture of DCs and cytotoxic T lymphocytes (CTLs) were used to evaluate the inhibitory effect of antigen-primed DCs on BCSCs. BCSC proliferation and doubling time were recorded ba
