Abstract

The invention provides a method for separating, purifying and culturing human blood and marrow dendritic cells, which includes the following steps that: hydroxyethyl starch and meglumine diatrizoate are used for preparing human blood and marrow dendritic cell-separating solution; sodium carbonate, sodium bicarbonate and CD123 antibody are used for producing a human blood and marrow dendritic cell culture flask; L-proline, insulin, vitamin C, L-glutamine, human umbilical cord blood plasm, recombinant human fibroblast growth factor and DMEM / F12 basic medium are used for preparing human blood and marrow dendritic cell culture solution; and human blood and marrow dendritic cells are separated, purified and cultured. The method for separating, purifying and culturing human blood and marrow dendritic cells can effectively prepare a large quantity of human blood and marrow dendritic cells, and is divided into four parts, and compared with the conventional method, the method has the advantages of simple and clear operation process and shorter operation time.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a method for separating, purifying and culturing human blood and bone marrow dendritic cells. Background technique [0002] Dendritic cells (dendritic cells; DC) are one of the antigen-presenting cells (APCs) present in peripheral blood, skin, lymphoid organs and thymus, and are enriched in lymphoid and non-lymphoid tissues. Dendritic cells have a strong ability to present antigens, which can express antigenic peptides to class I and class II dendritic cells, and activate CD4 and CD8 T cells, respectively, thereby inducing in vivo response to specific antigens (pathogenic microbial antigens) , tumor antigen, transplant antigen, etc.) immune response. The powerful immune-inducing function of DC is very suitable for immunotherapy (DC treatment) of various tumors. Previous reports have shown that DCs stimulated with Sendai virus (SeV) have strong anti-tumor effects in mouse ex...
