Summary:Described herein is a process for producing dendritic cells from peripheral blood precursor cells. The invention relates to methods by which such precursor cells are isolated and the CD34 antigen-expressing cells contained therein are enriched and expanded ex vivo in the presence of cytokines and hematopoietic growth factors such as erythropoietin, various interleukins and a granulocyte macrophage colony stimulating factor. Further disclosed are properties of antigen-presenting dendritic cells which arise after 10 to 20 days from the expanded precursor cells, and which may be purified further if necessary. Therapeutic applications in immunotherapy are included.
Abstract:Dendritic cells are of interest therapeutically as antigen-presenting cells. A process is disclosed in which peripheral blood cells are first isolated and the CD 34 antigen-expressing blood progenitor cells which they contain are then enriched. These enriched cells are expanded ex-vivo using a combination of haematopoietic growth factors and cytokines. Over a period of 10-20 days, they give rise, in particular to dendritic cells which, where appropriate, can be purified still further. These cells are functionally active with regard to the ability to present antigen.
