Obtained DC from PBMC recovered from one time used no leukocytes transfusion apparatus / 中国免疫学杂志

Objective:Got high purity dendritic cells from PBMC recovered from one time used no leukocytes transfusion apparatus.Methods:Rinsed PBMC with natural salt water from one time used no leukocytes transfusion apparatus and induced PBMC with GM-CSF and IL-4.Results:Got 5.1?10 7 PBMC from every one time used no leukocytes transfusion apparatus and 4.7?10 6 DCs with a purity of 96.9% were obtained.These DCs express CD86(96.1%)?CD40(88.9%)?CD83(91.6%)?HLA-DR(92.9%)?HLA-ABC(99%)?CD54(97.5%) highly and a few number of these DCs could stimulate proliferation of allogeneic mixed leukocyte reactions strongly.Conclusion:The results of this research supplied basic data for further research of DC and its clinical application.
