Abstract

Cells developing dendritic morphology were detected in cultures of highly purified human B cells incubated with 4β-phorbol 12-myristate 13-acetate (PMA). After 72 hr of culture, 2 to 7% of the cells had assumed a dendritic shape provided that contact with a plastic or glass surface also occurred. Dendritic cells developed in cultures of B cells prepared by positively selecting cells that stained with the B cell-specific monoclonal antibody B1 with the fluorescence-activated cell sorter. By contrast, dendritic cells could not be detected in cultures of cells obtained from patients with Bruton's type agammaglobulinemia that lacked B cells. Cells with dendritic morphology were nonspecific esterase negative and not phagocytic. They expressed HLA-DR, DQ, and DP antigens, receptors for interleukin 2 and transferrin, and were stained by B1 and 60.3, an antibody that identifies the β-chain common to lymphocyte function associated antigen-1, complement receptor 3, and the p150,95 antigen, but not by monoclonal antibodies to monocytes, complement receptors 2 or 3, NK cells, T cells, or Langerhans' cells. Formation of dendritic cells was inhibited by microtubule poisons (vinblastine, colchicine), a microtubule inhibitor (cytochalasin B), and the 60.3 monoclonal antibody, but not by inhibition of DNA synthesis. These data indicate that a subset of B cells is capable of assuming dendritic morphology after stimulation with phorbol esters and attachment to a surface. These dendritic cells exhibit characteristics that are quite similar to the interdigitating cells found in T cell-dependent areas of lymph nodes.
