Abstract Cytokine-mobilized peripheral blood cells have been shown to participate in hematopoietic recovery after bone marrow (BM) transplantation, and are proposed to be useful targets for retrovirus- mediated gene transfer protocols. We treated mice with granulocyte colony-stimulating factor (G-CSF) and stem cell factor (SCF) to mobilize hematopoietic progenitor cells into the peripheral blood. These cells were analyzed for the number and frequency of pluripotent hematopoietic stem cells (PHSC). We found that splenectomized animals treated for 5 days with G-CSF and SCF showed a threefold increase in the absolute number of PHSC over normal mice. The number of peripheral- blood PHSC increased 250-fold from 29 per untreated mouse to 7,200 in peripheral-blood PHSC in splenectomized animals treated for 5 days with G-CSF and SCF. Peripheral blood PHSC mobilized by treatment with G-CSF and SCF were analyzed for their ability to be transduced by retroviral vectors. Peripheral-blood PHSC from splenectomized animals G-CSF and SCF were transduced with a recombinant retrovirus containing the human MDR-1 gene. The frequency of gene transfer into peripheral blood PHSC from animals treated for 5 and 7 days was two-fold and threefold higher than gene transfer into PHSC from the BM of 5-fluorouracil-treated mice (P < .01). We conclude that peripheral blood stem cells mobilized by treatment with G-CSF and SCF are excellent targets for retrovirus- mediated gene transfer.

Abstract We have previously shown that FLT-3 ligand (FL) mobilizes murine hematopoietic primitive and committed progenitor cells into blood dose-dependently. Whether FL also acts synergistically with granulocyte colony-stimulating factor (G-CSF ) to induce such mobilization has now been investigated. Five- to 6-week-old C57BL/6J mice were injected subcutaneously with recombinant human G-CSF (250 μg/kg), Chinese hamster ovarian cell-derived FL (20 μg/kg), or both cytokines daily for 5 days. The number of colony-forming cells (CFCs) in peripheral blood increased approximately 2-, 21-, or 480-fold after administration of FL, G-CSF, or the two cytokines together, respectively, for 5 days. The number of CFCs in bone marrow decreased after 3 days but was increased approximately twofold after 5 days of treatment with G-CSF. The number of CFCs in the bone marrow of mice treated with both FL and G-CSF showed a 3.4-fold increase after 3 days and subsequently decreased to below control values. The number of CFCs in spleen was increased 24.2- and 93.7-fold after 5 days of treatment with G-CSF alone or in combination with FL, respectively. The number of colony-forming unit-spleen (CFU-S) (day 12) in peripheral blood was increased 13.2-fold by G-CSF alone and 182-fold by G-CSF and FL used together after 5 days of treatment. Finally, the number of preCFU-S mobilized into peripheral blood was also increased by the administration of FL and G-CSF. These observations show that FL synergistically enhances the G-CSF–induced mobilization of hematopoietic stem cells and progenitor cells into blood in mice, and that this combination of growth factors may prove useful for obtaining such cells in humans for transplantation.

Abstract Abstract 4444 Background: According to published data mobilization of sufficient number of CD 34+ cells with cytokines alone or with chemo-mobilization fails in 5–30% of patients. Plerixafor is a novel chemokine receptor 4 antagonist (CXCR4) that reversibly inhibits the interaction with its ligand SDF-1 (Stromal Derived Factor 1). Phase III studies have demonstrated that plerixafor combined with granulocyte-colony stimulating factor (GCSF) improves CD 34+ cell collection in patients with Multiple Myeloma (MM) or Non Hodgkin Lymphoma (NHL). It has been shown to be efficacious in combination with GCSF to mobilize adequate number of CD 34+ cells in patients proven to be poor mobilizers yielding a success rate of 60–100% in several reports. Plerixafor is currently approved for administration in combination with GCSF to enhance mobilization of hematopoietic stem cells in patients with lymphoma and MM whose cells mobilize poorly. Patients/methods: We administered plerixafor in combination with GCSF in 14 patients (in 4/14 as part of compassionate use protocol) and 2 sibling donors after an informed consent was obtained. Individuals were defined as poor mobilizers either due to unsuccessful collection of CD34+ >2×106/kg or due to peripheral blood CD34+ peak <20/μ l in spite of adequate mobilization treatment. Data of the individuals were collected retrospectively. Eight patients suffered from MM, 3 of NHL, 3 of H°dgkin Lymphoma (HL). Marrow involvement was present in 1 patient suffering from MM. The median number of previous chemotherapy regimens was 4(1-8). Two patients had a history of previous autologous hematopoietic cell transplantation (autoHCT) and 4 patients had received multiple radiotherapy courses. Patients had a median of 2 (1-3) previous unsuccessful attempts of mobilization before plerixafor plus GCSF administration. Nine patients had received GCSF alone and 5 patients chemotherapy plus GCSF. Patients received GCSF for 4 consecutive days and plerixafor was administered at the evening of the forth day, 10–11 hours before the scheduled aphaeresis procedure. In case of not sufficient or suboptimal number of CD34+ cells collection the procedure was repeated for maximum of 3 days plerixafor administration (7 days of GCSF). Results: Mobilization with plerixafor plus GCSF and collection of adequate number of CD 34+ cells was successful in 12/14 patients. The median number of CD 34+ cells collected was 2.5×106/kg in a median of 2 (1-4) apheresis days. Two of 14 patients proceeded to a second mobilization with plerixafor plus GCSF, eventually succeeding a sufficient cell dose graft collection. In 2 sibling female donors, aged 47 and 54 years, after administration of GCSF 10μ g/kg/day for 5 consecutive days mobilization was poor and collection of a graft with an acceptable CD 34+ cell dose was not possible. Administration of plerixafor improved mobilization and eventually grafts consisting of 2.55 ×106 and 5.34×106 CD34+/kg were collected by apheresis. Patients reported a grade ≤ II according to WHO scale toxicity following plerixafor administration. Most common side effects were hyperhidrosis, facial numbness and abdominal pain. None of the two healthy donors reported any adverse side effect. Engraftment was uneventfully in predictive time according to our historical data. Discussion: In our experience mobilization with either cytokines alone or cytokines following chemotherapy fails in a number of otherwise eligible for transplantation patients, mostly heavily pretreated or with advanced disease. In addition a small minority of healthy donors with no identifiable risk factors for poor mobilization, also fail mobilization with GCSF. The combination of plerixafor and GCSF seems to augment peripheral blood stem cells mobilization in poor mobilizers and offers a new treatment to collect sufficient CD 34+ cells and benefit from the transplantation procedure Disclosures: Off Label Use: Plerixafor was used for the mobilization of two healthy sibling donors after a signed concept was optained, due to poor mobilization with GCSF and failure of addequate graft collection.

Abstract We have previously identified a cellular population in murine bone marrow that facilitates engraftment of highly purified hematopoietic stem cells (HSC) across major histocompatibility complex (MHC) barriers without causing graft-versus-host disease. Here we investigated the effect of flt3 ligand (FL) and granulocyte colony-stimulating factor (G-CSF) on the mobilization of facilitating cells (FC) and HSC into peripheral blood (PB). Mice were injected with FL alone (day 1 to 10), G-CSF alone (day 4 to 10), or both in combination. The number of FC (CD8+/βTCR−/γδTCR−) and HSC (lineage−/Sca-1+/c-kit+) was assessed daily by flow cytometry. Lethally irradiated allogeneic mice were reconstituted with PB mononuclear cells (PBMC). FL and G-CSF showed a highly significant synergy on the mobilization of FC and HSC. The peak efficiency for mobilization of FC (21-fold increase) and HSC (200-fold increase) was reached on day 10. Our data further suggest that the proliferation of FC and HSC induced by FL in addition to the mobilizing effect mediated by G-CSF might be responsible for the observed synergy of both growth factors. Finally, the engraftment potential of PBMC mobilized with FL and G-CSF or FL alone was superior to PBMC obtained from animals treated with G-CSF alone. Experiments comparing the engraftment potential of day 7 and day 10 mobilized PBMC indicate that day 10, during which both FC and HSC reached their maximum, might be the ideal time point for the collection of both populations. © 1998 by The American Society of Hematology.
