Abstract:
Dendritic cells (DC) are antigen presenting cells (APC) that play critical roles in the initiation of T cell response and development of T cell-dependent antibodies in vivo. CD34_+ hematopoietic progenitor cells of bone marrow and peripheral blood can differentiate into DC when cultured with GM-CSF and TNF-? in vitro. In the present study, we cultured monocytes isolated from human peripheral blood with 100ng/ml hGM-CSF and 500U/ml hIL-4 for one week, and then found that a large number of DC with high purity were gengerated. DC expressed MHC I , MHC II and costimuladng moleculers highly on cell surface and cound stimulate proliferation of allogeneic T lymphocytes. Self serum or fetal calf serum are best for generation of DC. When hGM-CSF was used alone, the monocytes differentiated into macrophages but not to DC. TNF-? could induce further maturation of DC when added in late period of the culture. Generation of DC from human peripheral blood may facilitate further studies on DC and their clinical applications.
