Stimulating Factor

Colony stimulating factor-1 (CSF-1) regulates the survival, proliferation and differentiation of mononuclear phagocytes. The osteopetrotic (op/op) mutant mouse is devoid of CSF-1 due to an inactivating mutation in the CSF-1 gene and is deficient in several mononuclear phagocyte subpopulations. To analyze more fully the requirement for CSF-1 in the establishment and maintenance of mononuclear phagocytes, the postnatal development of cells bearing the macrophage marker antigens F4/80 and MOMA-1, in op/op mice and their normal (+/op or +/+) littermates, were studied during the first three months of life. In normal mice, maximum expression of tissue F4/80+ cells was generally correlated with the period of maximum organogenesis and/or cell turnover. Depending on the tissue, the F4/80+ cell density either decreased, transiently increased or gradually increased with age. In op/op mice, tissues that normally contain F4/80+ cells could be classified into those in which F4/80+ cells were absent and those in which the F4/80+ cell densities were either reduced, normal or initially normal then subsequently reduced. To assess which F4/80+ populations were regulated by circulating CSF-1 in normal mice, op/op mice in which the circulating CSF-1 concentration was restored to above normal levels by daily subcutaneous injection of human recombinant CSF-1 from day 3 were analyzed. These studies suggest that circulating CSF-1 exclusively regulates both the F4/80+ cells in the liver, spleen and kidney and the MOMA-1+ metallophilic macrophages in the spleen. Macrophages of the dermis, bladder, bone marrow and salivary gland, together with a subpopulation in the gut, were partially restored by circulating CSF-1, whereas macrophages of the muscle, tendon, periosteum, synovial membrane, adrenals and the macrophages intimately associated with the epithelia of the digestive tract, were not corrected by restoration of circulating CSF-1, suggesting that they are exclusively locally regulated by this growth factor. Langerhans cells, bone marrow monocytes and macrophages of the thymus and lymph nodes were not significantly affected by circulating CSF-1 nor decreased in op/op mice, consistent with their regulation by other growth factors. These results indicate that important differences exist among mononuclear phagocytes in their dependency on CSF-1 and the way in which CSF-1 is presented to them. They also suggest that the prevalent role of CSF-1 is to influence organogenesis and tissue turnover by stimulating the production of tissue macrophages with local trophic and/or scavenger (physiological) functions. Macrophages involved in inflammatory and immune (pathological) responses appear to be dependent on other factors for their ontogenesis and function.(ABSTRACT TRUNCATED AT 400 WORDS)

We have studied the production of plasminogen activator (PA) by mononuclear phagocytes derived from mouse bone marrow precursor cells (CFU-C) in culture. Bone marrow-derived macrophages (BMDM) obtained after 6-8-d cultivation in a liquid medium containing L-cell-conditioned medium (LCM), a source of colony stimulating factor (CSF), showed a high level of fibrinolytic activity comparable to that of thioglycollate medium-induced peritoneal macrophages (TPM) and at least 20-fold higher than that of resident peritoneal macrophages (RPM). Fibrinolysis was a result of active secretion of PA into the culture medium and plaques of caseinolysis could be detected by an overlay assay over all macrophage colonies formed after cloning of bone marrow cells in culture. When the fibrinolytic activity of BMDM harvested at different times was investigated, it was found that the level of PA activity of a given BMDM population correlated well with the incidence of cells (5-15 percent) able to proliferate and form colonies in agar after 7-14 d, somewhat more slowly than CFU-C. This correlation between the level of PA secretion and the incidence of agar colony-forming cells was also found with other mononuclear phagocyte populations. Active fibrinolysis and slow growing colony-forming cells were observed at the same time as adherent macrophages appeared, 2-3 d after the start of bone marrow culture, they persisted for 10 d before declining. Some of the factors which influenced PA production by BMDM were examined. Fibrinolysis could be enhanced two- to fourfold by exposing the cells for 4 h to concanavalin A (Con A), to medium conditioned by Con A-stimulated spleen cells and to LCM, but not by phagocytosis of latex particles. The substance in LCM that stimulated PA production appeared to be identical to CSF. Mononuclear phagocyte targets differed in their response to LCM, which stimulated fibrinolysis readily in BMDM, to a lesser extent in TPM and not at all in RPM. We conclude that CSF stimulates both proliferation and fibrinolytic activity in BMDM and that the level of macrophage activation, as defined by PA production, can be further enhanced by lymphokines. Induction of PA in BMDM provides a rapid and sensitive assay for measuring the activity of CSF and defining its role in macrophage activation.

Colony-stimulating factor-1 (CSF-1), the primary regulator of mononuclear phagocyte (M▹) production, exists as either a circulating or cell surface, membrane-spanning molecule. To establish transplacental transfer of maternal CSF-1, gestational day-17 mothers were injected intravenously with 125I-mouse CSF-1 or human rCSF-1, and the 125I-cpm or human CSF-1 concentrations were measured in fetal tissue, placenta, and fetal/maternal sera. Biologically active CSF-1 crossed the placenta and peaked in fetal tissue, placenta, and serum 10 minutes after injection. The role of CSF-1 in perinatal M▹ development was examined by studying the CSF-1–deficient osteopetrotic (csfmop/csfmop) mouse. Fetal/neonatal mice, derived from matings of either +/csfmopfemales with csfmop/csfmop males or the reciprocal pairings, were genotyped and tissue M▹ identified and quantified. In the presence of circulating maternal CSF-1 (+/csfmop mother), M▹ development incsfmop/csfmop liver was essentially complete at birth relative to +/csfmoplittermates, but significantly reduced in spleen, kidney, and lung. In the absence of circulating maternal CSF-1 (csfmop/csfmop mother), M▹ numbers at birth were reduced in csfmop/csfmopliver relative to the offspring of +/csfmopmothers, but were similar in spleen, kidney, and lung. We conclude that CSF-1 is required for the perinatal development of most M▹ in these tissues. Compensation for total absence of local CSF-1 production by circulating, maternal CSF-1 is tissue-specific and most prominent in liver, the first fetal organ perfused by placental blood. However, because some M▹ developed in the complete absence of CSF-1, other factors must also be involved in the regulation of macrophage development.

We have recently realized megakaryocyte (MK) colony formation in culture from blood and bone marrow progenitors using the plasma clot technique. In this study, the MK stimulating factor was an erythropoietin (Epo) either a poorly purified one(step III from anaemic sheep serum, a crude serum from anaemic mice, an urinary human Epo) or a highly purified one (GOLDWASSER). Similar results were obtained with all these Epo. A linear relationship was found between the number of colonies and seeded cells. However with less than 5.105 plated cells from the blood, no MK colonies were obtained, although erythroid colonies could be grown. In contrast, without Epo, spontaneous colonies could be observed which represented 1/5 th of the maximum plating efficiency , in these eases no erythroid colonies were present. These data suggest that Epo itself acts an a MK colony stimulating factor; but is not the only factor involved in the formation of MK colonies. This in vitro technique will be useful of in determining the factors regulating megakaryocytopoiesis.

Intestinal segmented filamentous bacteria (SFB) protect from ameba infection, and protection is transferable with bone marrow dendritic cells (BMDCs). SFB cause an increase in serum amyloid A (SAA), suggesting that SAA might mediate SFB's effects on BMDCs. Here we further explored the role of bone marrow in SFB-mediated protection. Transient gut colonization with SFB or SAA administration alone transiently increased the H3K27 histone demethylase Jmjd3, persistently increased bone marrowCsf2raexpression and granulocyte monocyte precursors (GMPs), and protected from ameba infection. Pharmacologic inhibition of Jmjd3 H3K27 demethylase activity during SAA treatment or blockade of granulocyte-macrophage colony-stimulating factor (GM-CSF) signaling in SFB-colonized mice prevented GMP expansion, decreased gut neutrophils, and blocked protection from ameba infection. These results indicate that alteration of the microbiota and systemic exposure to SAA can influence myelopoiesis and susceptibility to amebiasis via epigenetic mechanisms. Gut microbiota-marrow communication is a previously unrecognized mechanism of innate protection from infection.

The effects of colony-stimulating factor 1 (CSF-1), the primary regulator of mononuclear phagocyte production, are thought to be mediated by the CSF-1 receptor (CSF-1R), encoded by the c-fms proto-oncogene. To investigate the in vivo specificity of CSF-1 for the CSF-1R, the mouse Csf1r gene was inactivated. The phenotype ofCsf1−/Csf1r− mice closely resembled the phenotype of CSF-1-nullizygous(Csf1op/Csf1op) mice, including the osteopetrotic, hematopoietic, tissue macrophage, and reproductive phenotypes. Compared with their wild-type littermates, splenic erythroid burst-forming unit and high-proliferative potential colony-forming cell levels in bothCsf1op/Csf1op andCsf1−/Csf1r− mice were significantly elevated, consistent with a negative regulatory role of CSF-1 in erythropoiesis and the maintenance of primitive hematopoietic progenitor cells. The circulating CSF-1 concentration inCsf1r−/Csf1r− mice was elevated 20-fold, in agreement with the previously reported clearance of circulating CSF-1 by CSF-1R–mediated endocytosis and intracellular destruction. Despite their overall similarity, several phenotypic characteristics of theCsf1r−/Csf1r− mice were more severe than those of theCsf1op/Csf1op mice. The results indicate that all of the effects of CSF-1 are mediated via the CSF-1R, but that subtle effects of the CSF-1R could result from its CSF-1–independent activation.
