Abstract We have recently shown that nerve growth factor (NGF) promotes human granulopoiesis, specifically augmenting basophilic cell differentiation observed in methylcellulose hematopoietic colony assays of human peripheral blood. Because the NGF effect was seen in the presence of conditioned medium derived from a human T-cell line (Mo-CM) containing granulocyte-macrophage colony-stimulating factor (GM-CSF), we examined interactions of purified NGF and recombinant human GM-CSF (rhGM-CSF) on granulocyte growth and differentiation. rhGM-CSF stimulated a dose- dependent increase in methylcellulose colony growth at concentrations between 0.1 U/mL and 10 U/mL, and in the presence of NGF at 500 ng/mL this effect was enhanced. The number of basophilic cell colony-forming units (CFU-Baso) and histamine-positive colonies increased synergistically when NGF was added to rhGM-CSF. Furthermore, because Mo- CM acts with sodium butyrate to promote basophilic differentiation of alkaline-passaged myeloid leukemia cells, HL-60, we also examined the interaction of NGF and Mo-CM or rhGM-CSF using this assay. In the presence of NGF, Mo-CM at concentrations of 0.5% to 20% vol/vol, and rhGM-CSF at concentrations of 0.1 U/mL to 100 U/mL synergistically increased histamine production by butyrate-induced, alkaline-passaged HL-60 cells; this was associated with the appearance of metachromatic, tryptase-negative, IgE receptor-positive cells. The effects of rhGM-CSF or Mo-CM were completely abrogated by a specific anti-rhGM-CSF neutralizing antibody in methylcellulose, with or without NGF; the NGF synergy with rhGM-CSF in the HL-60 assay was also inhibited by either anti-rhGM-CSF or anti-NGF antibody. These studies support the notion that differentiation in the basophilic lineage may be enhanced by NGF acting to increase the number of GM-CSF-responsive basophilic cell progenitors.

Heparin-binding epidermal growth factor–like growth factor (HB-EGF) is a widely expressed EGF superfamily member that induces mitogenic and/or chemotactic activities toward different cell types through binding to EGF receptors 1 or 4. Membrane-bound HB-EGF exerts growth activity and adhesion capabilities and possesses the unique property of being the receptor for diphtheria toxin (DT). Using molecular and functional techniques, we show that human polymorphonuclear granulocytes (PMN), which did not express HB-EGF in resting conditions, expressed it at mRNA and protein level, following incubation with granulocyte-macrophage colony-stimulating factor (GM-CSF). Other classic agonists for PMN (including lipopolysaccharide, phagocytable particles, tumor necrosis factor-, or G-CSF) failed to induce HB-EGF. The effects of GM-CSF on HB-EGF mRNA levels were concentration-dependent, reached a plateau after 1 to 2 hours of stimulation, and did not require protein synthesis. After GM-CSF treatment, membrane-bound HB-EGF was detected by flow cytometry. At the same time, PMN acquired sensitivity to the apoptosis-promoting effect of DT, which, moreover, specifically suppressed the GM-CSF–induced priming of formyl-methionyl-leucyl-phenylalanine–stimulated superoxide anion release. Finally, soluble HB-EGF was detected in the PMN culture medium by a specific enzyme-linked immunosorbent assay. Thus, we provide evidence that HB-EGF is specifically inducible by GM-CSF in PMN and represents a novel peptide to be included in the repertoire of PMN-derived cytokines.

Abstract The UT-7 cell line was established from a patient with a megakaryoblastic leukemia (Komatsu et al, Cancer Res 51: 341, 1991). Its proliferation is strictly dependent on the presence of hematopoietic growth factors including erythropoietin (Epo), granulocyte-macrophage colony-stimulating factor (GM-CSF), and interleukin-3 (IL-3). We investigated the differentiation capacities of this cell line under the action of several growth factors, using immunomarkers, flow cytometry, and ultrastructural techniques. In the presence of GM-CSF and IL-3, eosinophil and basophil promyelocytes were detected, as well as a few cells with erythroid and megakaryocytic (MK) differentiation features. In contrast, Epo induced a marked erythroid differentiation with an increase of glycophorin A expression, accompanied by a few hemoglobinized cells. Differentiation induced by the growth factors took 24 to 48 hours to begin, and increased with cell passages to a plateau at 2 weeks of culture. However, this was not only due to a cell selection because the differential effects of Epo and GM-CSF were observed from a single cell clone and the phenotype could be reversed by opposite growth factors, even after a long period of culture. We subsequently investigated the phenotype of UT-7 in the presence of combinations of Epo, IL-3, and GM-CSF, and showed that GM-CSF and IL-3 act predominantly over Epo. This effect was mediated by a rapid downmodulation of Epo receptors by GM-CSF at messenger RNA and binding sites levels, without a change in receptor affinities. On the other hand, Epo had no effect on number and affinity of GM-CSF receptors. This study shows that UT-7 is a growth factor-dependent pluripotent cell line in which commitment may be directed by a hierarchical action of growth factors through an early and rapid transmodulation of growth factor receptors.

Juvenile chronic myelogenous leukemia (JCML) is a good model for the study of myeloproliferation because JCML hematopoietic progenitor cells grow in vitro at very low cell densities without the addition of exogenous stimulus. Previous studies have demonstrated that this proliferation is dependent on granulocyte-macrophage colony-stimulating factor (GM-CSF), and that removal of monocytes from the cell population before culture eliminates this “spontaneous” myeloproliferation, suggesting a paracrine role of monocyte stimulation. However, subsequent studies have shown that increased GM-CSF production from the JCML monocytes is not a consistent finding and therefore not a plausible sole mechanism. In examining hematopoietic growth factor dose- response curves, both JCML GM and erythroid nonadherent progenitor cell populations displayed a marked and selective hypersensitivity to GM- CSF. Responses to interleukin-3 and G-CSF were identical to control dose-response curves. This is the first demonstration of a myeloid leukemia in which hypersensitivity to a specific growth factor appears to be involved in the pathogenesis of the disease.

These studies support the notion that differentiation in the basophilic lineage may be enhanced by NGF acting to increase the number of GM-CSF-responsive basophilic cell progenitors.
