Dendritic cells are potent antigen-presenting cells derived from CD34+ haemopoietic stem cells. Dendritic cells have been reported to be generated from cells in granulocytic lineage as well as monocytes, blood dendritic cell precursors and lymphoid progenitors. In order to explore the differentiation pathway of dendritic cells from granulocytic cells and the applicability of leukaemia-derived dendritic cells for anti-leukaemic immunotherapy in acute leukaemia of granulocytic origin, we tried to generate dendritic cells from leukaemia cells of a patient with acute promyelocytic leukaemia (APL). Leukaemia cells were cultured with GM-CSF, IL-4 and TNF-alpha for 10 days. Azurophilic granule-containing cells with marked cytoplasmic projections were generated in the culture. FACS analysis of these cultured cells revealed the generation of CD1a+, CD83+, CD80+, CD86+, CD40+ and HLA-DR+ cells. The leukaemic origin of these dendritic-like cells was demonstrated by in situ hybridization of magnetic-bead-sorted CD1a+ dendritic cells using the DNA probes of t(15;17). Cells generated by culturing leukaemia cells were demonstrated to have a potent antigen-presenting function in allogeneic mixed leucocyte cultures. These findings show the plausibility of the previously reported pathway of dendritic cell maturation through granulocytic cells and suggest the possibility of anti-leukaemic immunotherapy using leukaemia-derived dendritic cells even in patients with acute promyelocytic leukaemia.

UI MeSH Term Description Entries
D007959 Lymphocyte Culture Test, Mixed Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.

D002454 Cell Differentiation Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs. Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D002884 Chromosomes, Human, Pair 15 A specific pair of GROUP D CHROMOSOMES of the human chromosome classification. Chromosome 15
D002886 Chromosomes, Human, Pair 17 A specific pair of GROUP E CHROMOSOMES of the human chromosome classification. Chromosome 17
D003713 Dendritic Cells Specialized cells of the hematopoietic system that have branch-like extensions. They are found throughout the lymphatic system, and in non-lymphoid tissues such as SKIN and the epithelia of the intestinal, respiratory, and reproductive tracts. They trap and process ANTIGENS, and present them to T-CELLS, thereby stimulating CELL-MEDIATED IMMUNITY. They are different from the non-hematopoietic FOLLICULAR DENDRITIC CELLS, which have a similar morphology and immune system function, but with respect to humoral immunity (ANTIBODY PRODUCTION).

D005260 Female Females
D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
