ABSTRACT The proliferation of neutrophil granulocyte lineage is driven largely by granulocyte colony-stimulating factor (G-CSF) acting via the G-CSF receptors. In this study, we show that mice lacking cyclin D3, a component of the core cell cycle machinery, are refractory to stimulation by the G-CSF. Consequently, cyclin D3-null mice display deficient maturation of granulocytes in the bone marrow and have reduced levels of neutrophil granulocytes in their peripheral blood. The mutant mice are unable to mount a normal response to bacterial challenge and succumb to microbial infections. In contrast, the expansion of hematopoietic stem cells and lineage-committed myeloid progenitors proceeds relatively normally in mice lacking cyclin D3, revealing that the requirement for cyclin D3 function operates at later stages of neutrophil development. Importantly, we verified that this requirement is specific to cyclin D3, as mice lacking other G1 cyclins (D1, D2, E1, or E2) display normal granulocyte counts. Our analyses revealed that in the bone marrow cells of wild-type mice, activation of the G-CSF receptor leads to upregulation of cyclin D3. Collectively, these results demonstrate that cyclin D3 is an essential cell cycle recipient of G-CSF signaling, and they provide a molecular link of how G-CSF-dependent signaling triggers cell proliferation.

Abstract Cytokine-mobilized peripheral blood hematopoietic stem cells (MPB HSC) are widely used for transplantation in the treatment of malignancies, but the mechanism of HSC mobilization is unclear. Although many HSC in bone marrow (BM) cycle rapidly and expand their numbers in response to cytoreductive agents, such as cyclophosphamide (CY), and cytokines, such as granulocyte colony-stimulating factor (G-CSF), MPB HSC are almost all in the G0 or G1phase of the cell cycle. This has raised the question of whether a subset of noncycling BM HSC is selectively released, or whether cycling BM HSC are mobilized after M phase, but before the next S phase of the cell cycle. To distinguish between these possibilities, mice were treated with one dose of CY followed by daily doses of G-CSF, and dividing cells were marked by administration of bromodeoxyuridine (BrdU) during the interval that BM HSC are expanding. After CY and 4 days of G-CSF, 98.5% of the 2n DNA content long-term repopulating MPB (LT)-HSC stained positively for BrdU, and therefore derived from cells that divided during the treatment interval. Next, LT-HSC from mice previously treated with a single dose of CY, which kills cycling cells, and 3 daily doses of G-CSF, were nearly all killed by a second dose of CY, suggesting that CY/G-CSF causes virtually all LT-HSC to cycle. Analysis of cyclin D2 messenger RNA (mRNA) expression and total RNA content of MPB HSC suggests that these cells are mostly in G1 phase. After CY/G-CSF treatment, virtually all BM LT-HSC enter the cell cycle; some of these HSC then migrate into the blood, specifically after M phase, and are rapidly recruited to particular hematopoietic organs.

Intervertebral disc (IVD) degeneration is a multifactorial process that is influenced by contributions from genetic predisposition, the aging phenomenon, lifestyle conditions, biomechanical loading and activities, and other health factors (such as diabetes). Attempts to decelerate disc degeneration using various techniques have been reported. However, to date, there has been no proven technique effective for broad clinical application. Granulocyte colony-stimulating factor (GCSF) is a growth factor cytokine that has been shown to enhance the availability of circulating hematopoietic stem cells to the brain and heart as well as their capacity for mobilization of mesenchymal bone marrow stem cells. GCSF also exerts significant increases in circulating neutrophils as well as potent anti-inflammatory effects. In our study, we hypothesize that GCSF can induce bone marrow stem cells differentiation and mobilization to regenerate the degenerated IVD. We found that GCSF had no contribution in disc regeneration or maintenance; however, there were cell proliferation within end plates. The effects of GCSF treatment on end plates might deserve further investigation.

Abstract Abstract 4815 Background and Aims: We reported that acute myelogenous leukemia blasts and chronic myelogenous leukemia cells converted to stromal myofibroblasts to create an environment for the proliferation of leukemic cells in vitro and also in a non-obese diabetes/ severe combined immunodeficiency (NOD/SCID) murine bone-marrow in vivo. In normal hematopoiesis, hematopoietic stem cell (HSC) and stromal immature mesenchymal stem cell (MSC) are speculated to have a cross-talk, and some reports indicate that the HSC generates MSC, and also a specific fraction of MSC shares similar molecular expressions to that of HSC. We made a hypothesis that HSC might be generated from MSC. To make clear this issue, expression cloning was performed to isolate a molecule that stimulated bone-marrow stromal myofibroblasts to express hematopoietic stem cell marker, CD34. And, we also observed the effect of the isolated molecule to an adult human dermal fibroblast (HDF). Materials and Methods: cDNA-expression library was constructed using PHA-P-stimulated normal human blood lymphocytes, and the prepared plasmids were transfected to COS7 cells. After 3 days of culture, supernatants were added to the normal human bone-marrow-derived myofibroblasts (final 10%), and cells were further cultured for one week. RNA was extracted from the cultured myofibroblasts, and cDNA was synthesized. Positive clones were selected on CD34-expression with reverse transcription-polymerase chain reaction, and a single clone was isolated. The purified protein from the isolated single clone was added to HDF-culture, and the morphological changes and the expression of specific hematopoiesis-related proteins were analyzed. Results and Discussion: Isolated single clone was human interleukin 1β (IL-1β). When the purified IL-1β protein was added to the bone-marrow-derived myofibroblast cultures, cell growth was increased, and up-regulation of the expression of several hematopoietic specific proteins, including cytokine receptors and transcription factor SCL, was observed. Based on these observations, we determined the effect of IL-1β to HDF. When HDFs were cultured with human IL-1β for 3 weeks, the expression of granulocyte colony-stimulating factor (G-CSF)-receptor, and SCL was increased. When these IL-1β-stimulated cells were cultured in a non-coated dish, cells were floating, and budding of the cells was also observed. When HDF were cultured with IL-1β for 3 weeks, and then G-CSF and erythropoietin were added to the cultures, expression of transcription factor GATA-1 and CEBPA was significantly increased after one week. These observations indicate that IL-1β can stimulate to induce HDF toward hematopoietic cells. Now we determine the precise actions of human IL-1β to HDF using NOD/SCID transplantation model in vivo. Disclosures: No relevant conflicts of interest to declare.

Abstract Many mutant mice deficient in leukocyte adhesion molecules display altered hematopoiesis and neutrophilia. This study investigated whether peripheral blood neutrophil concentrations in these mice are elevated as a result of accumulation of neutrophils in the circulation or altered hematopoiesis mediated by a disrupted regulatory feedback loop. Chimeric mice were generated by transplanting various ratios of CD18+/+ and CD18−/− unfractionated bone marrow cells into lethally irradiated wild-type mice, resulting in approximately 0%, 10%, 50%, 90%, or 100% CD18 null neutrophils in the blood. The presence of only 10% CD18+/+ neutrophils was sufficient to prevent the severe neutrophilia seen in mice reconstituted with CD18−/− bone marrow cells. These data show that the neutrophilia in CD18−/− mice is not caused by enhanced neutrophil survival or the inability of neutrophils to leave the vascular compartment. In CD18−/−, CD18−/−E−/−, CD18−/−P−/−, EP−/−, and EPI−/− mice, levels of granulocyte colony-stimulating factor (G-CSF) and interleukin-17 (IL-17) were elevated in proportion to the neutrophilia seen in these mice, regardless of the underlying mutation. Antibiotic treatment or the propensity to develop skin lesions did not correlate with neutrophil counts. Blocking IL-17 or G-CSF function in vivo significantly reduced neutrophil counts in severely neutrophilic mice by approximately 50% (P < .05) or 70% (P < .01), respectively. These data show that peripheral blood neutrophil numbers are regulated by a feedback loop involving G-CSF and IL-17 and that this feedback loop is disrupted when neutrophils cannot migrate into peripheral tissues.
