Abstract We recently demonstrated that GM-CSF, TGFβ1, and Notch ligand Delta-1, all of which are synthesized in the milieu of the skin, instruct human blood monocytes to differentiate into Langerhans cells (LCs) that are characterized by the expression of CD1a, Langerin, CLA, CCR6, and E-cadherin and the presence of Birbeck granules. Previous studies have shown similar biologic activities of GM-CSF and IL-3 on human blood monocytes. In the present study, we investigated whether GM-CSF and IL-3 have a similar action on blood monocytes with respect to their differentiation into LCs. In contrast to CD14+ monocytes cultured for 7 days in the presence of GM-CSF, TGF-β1, and Delta-1, the cells obtained from culture with IL-3, TGF-β1, and Delta-1 were negative for CLA, CCR6, Langerin, and E-cadherin. These cells expressed HLA-ABC, HLA-DR, CD80, CD86, CD40, CD54, and CD11c but not DC-SIGN. The expression level of CD1a declined, while CD14 was upregulated. The difference between cells cultured with GM-CSF, TGF-β1, and Delta-1 and those with IL-3, TGF-β1, and Delta-1 was corroborated by microarray analysis of the gene expression profiles. Thus, GM-CSF and IL-3 exert distinct effects on human blood monocytes in the presence of TGF-β1 and Delta-1. When GM-CSF was added to cultures containing IL-3, TGF-β1, and Delta-1, the phenotype of cultured cells closely resembled that observed with GM-CSF, TGF-β1, and Delta-1. As GM-CSF and IL-3 share common receptor β subunits, the signals mediated through GM-CSF receptor α subunits appear to be required for the development of LCs from monocytes. We also compared the action of GM-CSF with that of IL-3 in terms of the differentiation of monocytes into macrophages and dendritic cells (DCs). When CD14+ monocytes were cultured in the presence of GM-CSF or IL-3 for 7 days, the resulting macrophages obtained from both cultures were phenotypically indistinguishable. Next, we examined whether IL-3 as well as GM-CSF induces CD14+ monocytes to differentiate into DCs in the presence of IL-4. The phenotypic profiles in cells cultured with IL-3 plus IL-4 were parallel to those seen with DCs cultured in the presence of GM-CSF plus IL-4. These data suggest that although IL-3 can substitute for GM-CSF in the differentiation pathway of CD14+ monocytes toward macrophages or DCs, GM-CSF is indispensable for their LC development.

Abstract We previously demonstrated that Notch ligand Delta-1 in concert with GM-CSF and TGF-β1 promotes the differentiation of human blood monocytes into Langerhans cells that are characterized by the expression of CD1a, Langerhans-associated granules Langerin, cutaneous lymphocyte-associated antigen (CLA), CC chemokine receptor 6 (CCR6), and E-cadherin. These data extended the functional scope of Notch ligand Delta-1 in human adult hematopoiesis. HES-1 is known to be the target gene by Notch signaling. We examined the effect of Delta-1 on the expression of HES-1 mRNA in CD14+ blood monocytes in the presence of GM-CSF and TGF-β1, using real-time RT-PCR. When CD14+ blood monocytes were cultured with Delta-1, GM-CSF, and TGF-β1, the expression level of HES-1 mRNA increased approximately 10-fold at 24 hours of incubation, compared with the expression level in freshly isolated CD14+ monocytes. However, the expression level of HES-1 mRNA declined at 48 hours of incubation. This finding suggests that Delta-1 may operate at the early stage of the differentiation pathway from CD14+ monocytes to Langerhans cells. To explore this issue more precisely, we cultured CD14+ monocytes in the presence of Delta-1, GM-CSF, and TGF-β1 for 2 days, and subsequently replated the cells into the cultures without Delta-1. At day 7 of culture, cultured cells were harvested and characterized by phenotypic analysis. This initial 2-day exposure of CD14+ monocytes to Delta-1 gave rise to Langerhans cells, similar to the observation obtained with the supplementation of Delta-1 throughout 7-day culture. In turn, when Delta-1 was added at day 2 of culture, Langerhans cells were not induced, but instead the resulting cells exhibited the features of macrophages. Our results indicate that in response to Delta-1, human blood monocytes appear to initiate the differentiation program toward Langerhans cells, while they are incapable of differentiating into Langerhans cells after their commitment to macrophages.

Representing the most potent antigen-presenting cells, dendritic cells (DC) can now be generated from human blood monocytes. We recently presented a novel protocol employing GM-CSF, IL-4, and IFN-γto differentiate monocyte-derived DCin vitro. Here, such cells are characterized in detail. Cells in culture exhibited both dendritic and veiled morphologies, the former being adherent and the latter suspended. Phenotypically, they were CD1a-/dim, CD11a+, CD11b++, CD11c+, CD14dim/-, CD16a-/dim, CD18+, CD32dim/-, CD33+, CD40+, CD45R0+, CD50+, CD54+, CD64-/dim, CD68+, CD71+, CD80dim, CD86+/++, MHC class I++/+++HLA-DR++/+++HLA-DP+, and HLA-DQ+. The DC stimulated a strong allogeneic T-cell response, and further evidence for their autologous antigen-specific stimulation is discussed. Although resembling a mature CD 11c+CD45R0+blood DC subset identified earlier, their differentiation in the presence of the Thl and Th2 cytokines IFN-γand IL-4 indicates that these DC may conform to mature mucosal DC.

We have recently demonstrated that CD11b−/dullCD11c+ and CD11b+hiCD11c+ dendritic cell (DC) precursor subsets represent two distinct DC differentiation pathways from murine bone marrow lineage-phenotype negative (Lin−)c-kit+ hematopoietic progenitor cells (HPCs) stimulated with granulocyte-macrophage colony-stimulating factor (GM-CSF) + stem cell factor (SCF) + tumor necrosis factor  (TNF). We show here that transforming growth factor-β1 (TGF-β1) significantly inhibits the generation of these CD11b−/dullCD11c+ and CD11b+hiCD11c+ DC precursors. Phenotypically, this inhibitory effect was accompanied by markedly suppressed expression of Ia and CD86 antigens as well as major histocompatibility complex (MHC) class II transactivator (CIITA) and CC-chemokine receptor 7 (CCR7) mRNAs in Lin−c-kit+ HPC cultures stimulated with GM-CSF + SCF + TNF at day 6. TGF-β1 could also suppress mature DC differentiation from CD11b+hiCD11c+ DC precursors, but not the differentiation from CD11b−/dullCD11c+ DC precursors. In the absence of TNF, TGF-β1 markedly suppressed the expression of CIITA and CCR7 mRNAs in GM-CSF + SCF-stimulated Lin−c-kit+ HPCs at either day 6 or day 12 and induced the differentiation solely into monocytes/macrophages as evident in morphology, active phagocytic, and endocytic activities. These cells expressed high levels of F4/80 and E-cadherin antigens, but low or undetectable levels of Ia, CD86, and CD40 molecules. However, upon the stimulation with TNF + GM-CSF, these cells could further differentiate into mature DCs expressing high levels of Ia and E-cadherin, characteristics for Langerhans cells (LCs), and gained the capacity of enhancing allogenic MLR. Taken together, all of these findings suggest that TGF-β1 polarizes murine HPCs to generate LC-like DCs through a monocyte/macrophage differentiation pathway.

Human dendritic cells (DC) can now be generated in vitro in large numbers by culturing CD34+ hematopoietic progenitors in presence of GM-CSF+TNF alpha for 12 d. The present study demonstrates that cord blood CD34+ HPC indeed differentiate along two independent DC pathways. At early time points (day 5-7) during the culture, two subsets of DC precursors identified by the exclusive expression of CD1a and CD14 emerge independently. Both precursor subsets mature at day 12-14 into DC with typical morphology and phenotype (CD80, CD83, CD86, CD58, high HLA class II). CD1a+ precursors give rise to cells characterized by the expression of Birbeck granules, the Lag antigen and E-cadherin, three markers specifically expressed on Langerhans cells in the epidermis. In contrast, the CD14+ progenitors mature into CD1a+ DC lacking Birbeck granules, E-cadherin, and Lag antigen but expressing CD2, CD9, CD68, and the coagulation factor XIIIa described in dermal dendritic cells. The two mature DC were equally potent in stimulating allogeneic CD45RA+ naive T cells. Interestingly, the CD14+ precursors, but not the CD1a+ precursors, represent bipotent cells that can be induced to differentiate, in response to M-CSF, into macrophage-like cells, lacking accessory function for T cells. Altogether, these results demonstrate that different pathways of DC development exist: the Langerhans cells and the CD14(+)-derived DC related to dermal DC or circulating blood DC. The physiological relevance of these two pathways of DC development is discussed with regard to their potential in vivo counterparts.
