Abstract:
An objective of the present invention is to provide methods for producing dendritic cells (DCs), which comprise the step of culturing DC precursor cells in the presence of a plurality of cytokines, produced dendritic cells, and uses thereof.The present inventors discovered that dendritic cells with a high IL-12 productivity can be obtained by culturing DC precursor cells in the presence of a plurality of cytokines, followed by about one week of culture in the presence of GM-CSF and IL-4. The present invention enables preparation of a large amount of DCs with a high IL-12 productivity from a small number of DC precursor cells, and therefore makes it easier to increase the number of DCs for administration in DC-based anti-tumor immune therapy, treatment of infections, etc. Thus, the effect of DC vaccines is expected to be enhanced.
