Recombinant GM-CSF Induces in Vitro Differentiation of Dendritic Cells from Mouse Bone Marrow
1993
The unprecedented functional capacity of dendritic cells (DC) in sensitizing resting T cells and their role in triggering T dependent immune responses attract increasing interest in this unique accessory cell population. Like macrophages (Mph) DC have been described to originate in the bone marrow (BM) (1). While the cytokine-promoted in vitro differentiation of Mph from BM-cells is well established, a convincing in vitro culture system for propagating mouse DC from BM-cells has not yet been reported. This work demonstrates the differentiation of DC from mouse bone marrow cells by a short term in vitro culture system supplemented with rGM-CSF.
Uptake of microparticle-adsorbed protein antigen by bone marrow-derived dendritic cells results in up-regulation of interleukin-1α and interleukin-12…

Dendritic cells synthesize and express major histocompatibility complex (MHC) class II peptide-binding elements constitutively and, therefore, belong to the category of professional antigen-presenting cells. Unlike other cells that show constitutive class II expression, such as B cells and certain T cell clones, dendritic cells possess the unique capacity to activate naive T cells. Using dendritic cells generated in vitro by culture of mouse bone marrow in the presence of low doses of recombinant mouse granulocyte/macrophage colony-stimulating factor, we found that discrete maturation stages of these cells can be distinguished which were correlated with defined functional capabilities. The …
Development of Rat DC by in Vitro Culture of Bone Marrow Cells
1995
Dendritic cells (DC) represent a subpopulation of leukocytes of bone marrow (BM) origin, involved in crucial immunological reactions. DC play a fundamental role in the primary immune response by stimulating quiescent T cells. In this study we describe an in vitro culture system to raise DC from unfractionated bone marrow (BM) cells of LEWIS rats in the presence of low doses of mouse recombinant GM-CSF, that was successfully used in previous work to culture mouse DC1,2,3.
Full length cDNA of rat RT1.DMa and RT1.DMb and expression of RT1.DM genes in dendritic and Langerhans cells.
1997
MHC encoded DM heterodimers and classical MHC class II complexes meet in an endosomal/lysosomal compartment where DM heterodimers support peptide loading of MHC class II. Studies on peptide loading of rat class II and on peptide persistence in cells of the dendritic lineage prompted us to establish full length cDNA clones coding for the subunits alpha and beta of rat DM molecules as well as a mAb directed against the luminal moiety of the beta subunit. Here we describe the establishment of the first full length cDNA clones of rat RT1.DMa and RT1.DMb. The mode of expression of RT1.DM at the transcript level in bone marrow culture-derived dendritic cells, in Langerhans cells and in a number o…
Uptake of Bead-Adsorbed Versus Soluble Antigen by Bone Marrow Derived Dendritic Cells Triggers Their Activation and Increases Their Antigen Presentat…
1995
The property to internalize particles has for long time been ascribed primarily to macrophages. DC in contrast were considered generally as phagocytosis negative. Fully mature DC which can be isolated from various tissues of the body do indeed not take up particulate material; however immature DC which arise in differentiating bone marrow cultures do exhibit phagocytic capacity1. Consistent with their immature phenotype epidermal Langerhans cells were also described to possess phagocytic potential2.
