We describe here that lineage phenotype- negative (Lin)−c-kit+ hematopoietic progenitor cells (HPCs) from day 13 postcoitus (dpc) murine fetal liver (FL) can generate dendritic cell (DC) precursors when cultured in vitro in the presence of PA6 stromal cells plus granulocyte/macrophage colony-stimulating factor (GM-CSF) + stem cell factor (SCF) + Flt3 ligand (Flt3L) for 12 to 14 days, and develop into mature DCs when stimulated with GM-CSF plus mouse tumor necrosis factor  (mTNF) for an additional 3 to 5 days. A transwell culture system showed that the generation of DC precursors depended on the support of PA6 cell-secreted soluble factor(s). The mature DCs derived from 13 dpc FL Lin−c-kit+ HPCs showed characteristic morphology and function of DCs and expressed high levels of Ia, CD86, and CD40 molecules, low levels of DEC205, E-cadherin, and F4/80 molecules, but barely detectable CD11c antigen. Once FL-derived HPCs were cultured without GM-CSF, NK1.1+ cells developed in the presence of PA6 cells + SCF + Flt3L. These NK1.1+ cells could develop into DC precursors at an earlier stage of differentiation by reculturing with PA6 cells + SCF + Flt3L + GM-CSF, but they would be irreversibly committed to NK cell precursors without GM-CSF after 3 days, suggesting that GM-CSF plays a critical role in controlling the transition of DC and NK cell precursors from 13 dpc FL-derived Lin−c-kit+ HPCs. This study represents the first success in generating mature DCs in vitro from murine FL HPCs. (Blood. 2000;95:138-146)

Abstract Dendritic cells (DCs) comprise heterogenous and functionally diverse populations of antigen presenting cells. Their developmental pathways remain largely unknown. Using a transcriptional profiling approach, we identified Gfi1 as a novel critical transcription factor in GM-CSF-dependent DC differentiation. Gfi1 is expressed in precursor and mature DCs, as seen in Gfi+/GFP mice, in which one Gfi1 allele is replaced by the GFP cDNA. Gfi1−/ − mice showed a global reduction of myeloid and lymphoid DCs in all lymphoid organs whereas epidermal Langerhans cells were enhanced in number. Gfi1−/ − DCs showed marked phenotypic and functional alterations, as exemplified by decreased MHC class II expression, absent upregulation of costimulatory molecules upon stimulation and reduced ability to stimulate specific T-cell responses. In contrast, Gfi1−/ − DCs exhibited an increased activation profile as assessed by enhanced secretion of IL12. In vitro, Gfi1−/ − hematopoietic progenitor cells were unable to develop into DCs in the presence of GM-CSF or Flt3L. Instead, they differentiated into macrophages, as evidenced by morphology, expression of cell surface markers, and functional properties. These findings suggest that Gfi1 is a critical modulator of DC versus macrophage development. Analysis of hematopoietic chimeras upon transplantation into congenic recipient mice established a cell-autonomous and non-redundant role for Gfi1 in DC development. Furthermore, upon retroviral gene transfer into Gfi1−/ − progenitor cells, the developmental defect could be reconstituted in vitro and in vivo. The inability of Gfi1−/ − hematopoietic progenitor cells to develop into DCs was associated with decreased STAT3 activation, as shown by Western blot and EMSA assays. In conclusion, we have identified Gfi1 as a critical transcription factor that controls DC versus macrophage development and dissociates DC maturation and -activation.

Abstract The Notch signaling system regulates proliferation and differentiation in many tissues. Notch is a transmembrane receptor activated by ligands expressed on adjacent cells. Hematopoietic stem cells and early progenitors express Notch, making the stromal cells which form cell-cell contacts with progenitor cells candidate ligand-presenting cells in the hematopoietic microenvironment. Therefore, we examined primary stromal cell cultures for expression of Notch ligands. Using reverse transcription-polymerase chain reaction, in situ hybridization, immunohistochemistry, and Western blotting, we demonstrate expression of Jagged 1 in primary stromal cultures. To investigate if the stromal expression of Jagged 1 has functional effects on hematopoietic progenitors, we cultured CD34+, c-kit+ hematopoietic progenitor cells derived from the aorto gonadal mesonephros region of day 11 mouse embryos on the Jagged 1− stromal cell line S17 and on S17 cells engineered to express Jagged 1. The presence of Jagged 1 increased the number of colonies formed in subsequent methylcellulose culture fourfold. Larger increases in colony numbers were observed under the same culture conditions with CD34+, c-kit+ hematopoietic progenitor cells derived from d11 fetal liver. These results obtained in vitro table Jagged 1 as a candidate regulator of stem cell fate in the context of stromal microenvironments in vivo. © 1998 by The American Society of Hematology.

We studied the effects of a series of well-characterized clones of human natural killer (NK) cells on the proliferation of highly purified normal marrow hematopoietic progenitor cells. Individual NK clones suppressed granulocyte, monocyte, erythroid, or mixed colony formation in a heterogeneous but clonally stable manner. Inhibition of colony growth required a period of close cell contact between NK cell and progenitor cell with maximum inhibition occurring after 8 to 18 hours of preincubation time. The mechanism of killing was at least partially humoral, however, as cell-free supernatants generated by NK clones “activated” by contact with a target cell also inhibited progenitor cell growth. One of the possible humoral mediators was identified as gamma-interferon by studies with specific neutralizing monoclonal antibodies. These results show that clonal NK lines can be further activated by coming in contact with hematopoietic progenitor cells, resulting in substantial inhibition of colony formation in vitro.

To test the hypothesis that the c-kit ligand plays an important role in the regulation of early events occurring during human hematopoiesis, we determined the effect of a recombinant form of c-kit ligand, termed mast cell growth factor (MGF), on the high-proliferative potential colony-forming cell (HPP-CFC) and the cell responsible for initiating long-term hematopoiesis in vitro (LTBMIC). MGF alone did not promote HPP-CFC colony formation by CD34+ DR- CD15- marrow cells, but synergistically augmented the ability of a combination of granulocyte- monocyte colony-stimulating factor (GM-CSF) interleukin (IL)-3 and a recombinant GM-CSF/IL-3 fusion protein (FP) to promote the formation of HPP-CFC-derived colonies. MGF had a similarly profound effect on in vitro long-term hematopoiesis. Repeated additions of IL-3, GM-CSF, or FP alone to CD34+ DR- CD15- marrow cells in a stromal cell-free culture system increased cell numbers 10(3)-fold by day 56 of long-term bone marrow culture (LTBMC), while combinations of MGF with IL-3 or FP yielded 10(4)- and 10(5)-fold expansion of cell numbers. Expansion of the number of assayable colony-forming unit-granulocyte-monocyte (CFU- GM) generated during LTBMC was also markedly enhanced when MGF was added in combination with IL-3 or FP. In addition, MGF, IL-3, and FP individually led to a twofold to threefold increase in HPP-CFC numbers after 14 to 21 days of LTBMC. Furthermore, the effects of these cytokines on HPP-CFC expansion during LTBMC were additive. Throughout the LTBMC, cells receiving MGF possessed a higher cloning efficiency than those receiving IL-3, GM-CSF, or FP alone. These data indicate that the c-kit ligand synergistically interacts with a number of cytokines to directly augment the proliferative capacity of primitive human hematopoietic progenitor cells.

Abstract CCAAT enhancer binding protein-α (C/EBPα) inhibits proliferation in multiple cell types; therefore, we evaluated whether C/EBPα-deficient hematopoietic progenitor cells (HPCs) have an increased proliferative potential in vitro and in vivo. In this study we demonstrate that C/EBPα-/- fetal liver (FL) progenitors are hyperproliferative, show decreased differentiation potential, and show increased self-renewal capacity in response to hematopoietic growth factors (HGFs). There are fewer committed bipotential progenitors in C/EBPα-/- FL, whereas multipotential progenitors are unaffected. HGF-dependent progenitor cell lines can be derived by directly culturing C/EBPα-/- FL cells in vitro Hyperproliferative spleen colonies and myelodysplastic syndrome (MDS) are observed in mice reconstituted with C/EBPα-/- FL cells, indicating progenitor hyperproliferation in vitro and in vivo. C/EBPα-/- FL lacked macrophage progenitors in vitro and had impaired ability to generate macrophages in vivo. These findings show that C/EBPα deficiency results in hyperproliferation of HPCs and a block in the ability of multipotential progenitors to differentiate into bipotential granulocyte/macrophage progenitors and their progeny.

Abstract The anatomic site of hematopoiesis changes during fetal development from the yolk sac to the liver and finally to the marrow. Factors controlling this switch in the site of hematopoiesis are unknown. We assayed erythroid colony (CFU-E) and erythroid burst (BFU-E) formation in fetal, newborn, and adult baboon liver and marrow to determine the growth requirements of primate hematopoietic progenitor cells from different anatomic sites and developmental stages. We cocultured fetal, newborn, and adult liver and marrow nonadherent cells with adherent cells from these organs to assess the role adherent cells may play in determining the site of hematopoiesis. Fetal liver, fetal marrow, newborn marrow, and adult marrow cultures formed CFU-E and BFU-E colonies in vitro. In contrast, newborn and adult liver cell cultures very rarely formed colonies. However, when newborn or adult liver nonadherent cells were cocultured with marrow adherent cells, CFU-E and BFU-E colonies were detected. The colonies that formed in the newborn and adult liver cultures were derived from the liver and not from the marrow cells or peripheral blood trapped in the liver. These data suggest that in contrast to fetal liver, newborn and adult liver may not be hematopoietic organs in normal primates in vivo because of changes in the growth requirements of hematopoietic progenitor cells present in these organs.
