title: BDCM: a novel B-cell line with genetic and functional similarity to dendritic cells.
abstract: We describe a B-cell line, BDCM, which arose spontaneously from culture of a pheresis product from a patient with M5a myeloid leukaemia. Cell growth was associated with autocrine activation of the signal transducer and activator of transcription 1 (Stat-1) transcription factor. Although the cells expressed several B-cell surface markers and had a rearranged immunoglobin J region, they also exhibited several characteristics associated with dendritic cells. These included extensive surface projections, cross-priming ability and strong T cell-stimulating capability. In addition, the cytokine production profile of BDCM cells was nearly identical to that of mature monocyte-derived dendritic cells.
