Abstract Human multilineage colony-stimulating factor (multi-CSF)/interleukin-3 (IL-3) induces colony formation from CFU-GEMM, BFU-E, and CFU-Eo when applied to in vitro cultures of highly enriched hematopoietic progenitor cells. No granulocytic colonies are formed in response to IL- 3. However, with appropriate assays, we demonstrate that IL-3 increases the size of G-CSF-induced granulocytic colonies; these colonies contain greater proportions of immature cells as compared with colonies stimulated by G-CSF alone. Furthermore, IL-3 promotes the survival of CFU-G in vitro, whereas in cultures not supplemented with IL-3, CFU-G extinguish within seven days. We conclude that IL-3, although it does not stimulate granulocytic colony formation by itself, regulates the survival and proliferative rate of granulocytic progenitors.

Receptors for murine leukemia inhibitory factor (LIF) were demonstrated on immature and mature murine megakaryocytes. LIF alone had no effects in culture on the survival or proliferation of normal murine megakaryocytes or their precursors. However, combination of LIF with multipotential-colony-stimulating factor (Multi-CSF) (interleukin-3) enhanced the megakaryocyte colony formation able to be stimulated by Multi-CSF; the enhancement involved all types of megakaryocyte colony and resulted in the formation of increased numbers of megakaryocytes. These observations provide a possible basis for the observation that, when LIF is injected in vivo, elevations are observed in megakaryocyte numbers and platelet levels.

Abstract CD34+ cells isolated from bone marrow or umbilical cord blood from healthy donors were studied for proliferation and differentiation in liquid cultures in the presence of recombinant human granulocyte- monocyte colony-stimulating factor (GM-CSF), granulocyte CSF (G-CSF), monocyte CSF (M-CSF), and interleukin-3 (IL-3), followed by immunophenotyping for myeloid and myeloid-associated cell surface markers. IL-3, either alone or together with GM-CSF, G-CSF, or M-CSF, induced, on average, 50-fold cell multiplication, GM-CSF five fold to 10-fold, and G-CSF and M-CSF less than fivefold. Cells from cultures stimulated with GM-CSF, G-CSF, or M-CSF alone contained cells with a “broad” myeloid profile, “broader” than observed in cultures with IL-3. However, since IL-3 induced rapid cell multiplication, high numbers of cells expressing early (CD13, CD33) and late myeloid markers (CD14, CD15) were recovered. The presence of other CSFs together with IL-3 did not alter the IL-3-induced effect on the cells. When 5,000 CD34+ cells were cultured with IL-3 alone, the cultures still contained 2,000 to 5,000 CD34+ cells after 14 days of culture, while cells cultured with GM-CSF, G-CSF, or M-CSF contained less than 1,000 CD34+ cells. Furthermore, 1,000 to 3,000 cells were positive for the megakaryocytic lineage marker CD41b after cultures with GM-CSF or IL-3, while cultures with G-CSF or M-CSF did not contain detectable numbers of CD41b+ cells. Finally, erythroid cells could also be generated from purified CD34+ cells. The results show that IL-3 and GM-CSF can induce rapid proliferation of purified CD34+ cells in vitro with differentiation to multiple myeloid lineages, while certain subsets maintain expression of CD34.

Abstract Pure murine colony-stimulating factor-1 (CSF-1) was assessed for its effects in vivo in mice pretreated seven days earlier with a sublethal dosage of cyclophosphamide. The multipotential (CFU-GEMM), erythroid (BFU-E), and granulocyte-macrophage (CFU-GM) progenitor cells in these mice were in a slowly cycling or noncycling state. Intravenous administration of 20,000 units of CSF-1 to these mice stimulated the hematopoietic progenitors into a rapidly cycling state in the marrow and spleen within three hours. Significant increases in absolute numbers of marrow and spleen CFU-GM and spleen BFU-E and CFU-GEMM were also detected. No endotoxin was detected in the CSF-1 preparation by Limulus lysate assay, and treatment of CSF-1 at 100 degrees C for 20 to 30 minutes completely inactivated the in vitro and in vivo stimulating effects. The effects of CSF-1 were not mimicked by the in vivo administration of 0.1 to 10 ng Escherichia coli lipopolysaccharide. These results suggest that the effects of CSF-1 in vivo were not due to contaminating endotoxin or to a nonspecific protein effect. CSF-1 did not enhance colony formation by BFU-E or stimulate colony formation by CFU-GEMM in vitro, thus suggesting that at least some of the effects of CSF-1 noted in vivo are probably indirect and mediated by accessory cells.

Abstract To study the relationship between hematopoietic factors and their responsive hematopoietic progenitors in the differentiation process, both purified factors and enriched progenitors are required. We isolated total CD34+ cells, CD34+,CD33+ cells, and CD34+,CD33- cells individually from normal human bone marrow cells by fluorescence- activated cell sorter (FACS), and examined the effects of granulocyte colony-stimulating factor (G-CSF), interleukin-3 (IL-3), and IL-5 on in vitro colony formation of these cells. CD34+,CD33+ cells formed granulocyte colonies in the presence of G-CSF. Both CD34+,CD33+ cells and CD34+,CD33- cells formed granulocyte/macrophage colonies in the presence of IL-3. Eosinophil (Eo) colonies were only formed by CD34+,CD33- cells in response to IL-3, but scarcely formed by CD34+ cells in the presence of IL-5. We performed the two-step cultures consisting of the primary liquid culture for 6 days and the secondary methylcellulose culture, and serially examined changes in phenotypes of ,he cells cultured in the primary culture. CD34-,CD33+ cells derived from CD34+,CD33+ cells by preincubation with G-CSF or IL-3 formed Eo colonies in the presence of IL-5 but not IL-3. CD34-,CD33+ cells derived from CD34+,CD33- cells by preincubation with IL-3 also formed Eo colonies by support of IL-5 as well as IL-3. Both CD34+ cells gradually lost the CD34 antigen by day 6 of incubation with G-CSF or IL- 3. Loss of this antigen was well-correlated with acquisition of susceptibility to IL-5. It was concluded that G-CSF supported the neutrophil differentiation of committed colony-forming cells, IL-3 supported that of both committed and multipotent colony-forming cells. G-CSF and IL-3 also supported the early stage of E. differentiation; IL- 5 supported the late stage of that.

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.
