OBJECTIVE     This research was to induce dendritic cells (DCs) from mice embryonic stem cells and bone marrow mononuclear cells in vitro , and then compare the biologic  characteristics of  them.
METHODS    Embryonic stem cells (ESCs) suspending cultured in petri dishes were induced to generate embryonic bodies (EBs). Fourteen-day well-developed EBs were transferred to histological culture with the same medium and supplemented 25 ng/ml GM-CSF and 25 ng/ml IL-3. In the next 2 weeks, there were numerous immature DCs outgrown. Meantime, mononuclear cells isolated from mice bone marrow were induced to derive dendritic cells by supplementing 25 ng/ml GM-CSF and 25 ng/ml IL-4, and then the morphology, phenotype and function of both dendritic cells rom different origins were examined.
RESULTS    Growing mature through exposure to lipopolysaccharide (LPS), both ESC-DCs and BM-DCs exhibited dramatic veils of cytoplasm and extensive dendrites on their surfaces, highly expressed CD11c, MHC-II and CD86 with strong capacity to stimulate primary T cell responses in mixed leukocyte reaction (MLR) .
CONCLUSION    ESC-DC has the same biologic characteristics as BM-DC, and it provides a new, reliable source for the functional research of DC and next produce corresponding anti-tumor vaccine.
