A Tender Reduced-Intensity Conditioning for the Unfit: A Novel 4 Gy Total Body Irradiation-Based Conditioning Followed by Two-Step Haploidentical Stem Cell Transplant, Results of a Prospective Trial. Transplant Cell Ther 2024:S2666-6367(24)00551-7. [PMID: 39084263 DOI: 10.1016/j.jtct.2024.07.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 07/24/2024] [Accepted: 07/26/2024] [Indexed: 08/02/2024]
Abstract
Allogeneic hematopoietic stem cell transplant (HSCT) remains the only potentially curative treatment for many hematologic malignancies (HM). We previously developed a two-step approach that separates the lymphoid and myeloid portions of the graft, allowing a consistent T cell dosing and sparing the stem cells from the effect of post-transplant cyclophosphamide (CY). The two-step approach demonstrated safety and efficacy in patients treated with myeloablative and reduced-intensity conditioning. Here, we extended our two-step platform to older and less fit patients and explored the effects of using a high dose of T cells on disease relapse and transplant outcomes. Thirty-four patients with HM were treated. Median age was 68 years old and included a minority population constituting 32%. Eighty-two percent had a hematopoietic cell transplantation comorbidity index score ≥3. Ninety-one percent were haploidentical, and the rest were matched-related donor HSCT. Following administration of fludarabine and 2 Gy total body irradiation (TBI) (13 patients) or 4 Gy TBI (21 patients) conditioning regimen, a fixed dose of 2 × 108/kg CD3+ T cells was given, followed 2 days later by CY, then infusion of CD34-selected stem cells. Overall survival (OS) was 70% at 1 year and 48% at 3 years. The cumulative incidence (CI) of non-relapse mortality (NRM) and relapse were 22% and 33% at 3 years. However, the CI of relapse was much lower for patients treated with 4 Gy TBI versus those treated with 2 Gy TBI (11% versus 54%, P = .045), while NRM was similar (23% versus 15%, P = .399). This contributed to a high OS of 64% in patients who received 4 Gy TBI-based conditioning at 3 years, with median OS not reached, although this was not statistically significant (P = .68). The median time to neutrophil and platelet recovery was 12 and 17 days, respectively. The CI of grade II acute graft-versus-host-disease (aGVHD) was 22% and 26% at 100 days and 6 months, respectively. The CI of chronic GVHD (cGVHD) was 7.5% at 3 years. There was no grade III or IV aGVHD, no severe cGVHD, and no deaths attributable to GVHD. In conclusion, the two-step approach HSCT demonstrated a low disease relapse rate and high survival in patients treated with 4 Gy TBI-based conditioning, despite a generally older and more medically compromised patient population.

Abstract
Background In response to the replace mammal research models with insects in preliminary immunological studies, interest has grown in invertebrate defense systems. The immunological response is regulated by cytokines; however, while their role in mammals is well understood, little is known of their function in insects. A suitable target for studies into insect immunology is Galleria mellonella (Lepidoptera), the wax moth: a common host for human fungal and bacterial pathogens. G. mellonella is also a perfect subject for studies into the presence of cytokine-like proteins. Specific objectives The main goal of present research was detection in insect immunocompetent cells the 18 mammalian cytokines (IL-1α, IL-1β, IL-2, IL-3, IL-6, IL-7, IL-8, IL-12, IL-13, IL-15, IL-17, IL-19, IFN-γ, TNF-α, TNF-β, GM-CSF, M-CSF, G-CSF), which play important role in immunological response and indication how their level change after fungal infection. Methodology The changes of cytokine-like proteins level were detected in hemocytes taken from G. mellonella larvae infected with entomopathogenic fungus, C. coronatus. The presence of cytokine-proteins was confirmed with using fluorescence microscopy (in cultured hemocytes) and flow cytometry (in freshly collected hemolymph). The ELISA test was used to detect changes in concentration of examined cytokine-like proteins. Results Our findings indicated the presence of eighteen cytokine-like molecules in G. mellonella hemocytes during infection with C. coronatus. The hemocytes taken from infected larvae demonstrated higher fluorescence intensity for six cytokine-like proteins (GM-CSF, M-CSF, IL-3, IL-15, IL-1β and IL-19) compared to untreated controls. ELISA test indicated significantly higher IL-3 and IL-15. M-CSF, IL-1α and IL-19 concentration in the hemolymph after fungal infection, and significantly lower TNF-β and G-CSF. Conclusions Our findings confirm that the selected cytokine-like molecules are present in insect hemocytes and that their concentrations change after fungal infection, which might suggest that they play a role in the anti-fungal immunological response.

Abstract
Objectives Recombinant granulocyte colony-stimulating factor (G-CSF) is frequently administered to patients with cancer to enhance granulocyte recovery post-chemotherapy. Clinical trials have also used G-CSF to modulate myeloid cell function in pregnancy and inflammatory diseases. Although the contribution of G-CSF to expanding normal granulocytes is well known, the effect of this cytokine on the phenotype and function of immunosuppressive granulocytic cells remains unclear. Here, we investigate the impact of physiological and iatrogenic G-CSF on an as yet undescribed granulocyte phenotype and ensuing outcome on T cells in the settings of cancer and pregnancy. Methods Granulocytes from patients treated with recombinant G-CSF, patients with late-stage cancer and women enrolled on a trial of recombinant G-CSF were phenotyped by flow cytometry. The ability and mechanism of polarised granulocytes to suppress T-cell proliferation were assessed by cell proliferation assays, flow cytometry and ELISA. Results We observed that G-CSF leads to a significant upregulation of CD14 expression on CD15+ granulocytes. These CD15+CD14+ cells are identified in the blood of patients with patients undergoing neutrophil mobilisation with recombinant G-CSF, and physiologically in women early in pregnancy or in those treated as a part of a clinical trial. Immunohistochemistry of tumor tissue or placental tissue identified the expression of G-CSF. The G-CSF upregulates the release of reactive oxygen species (ROS) in CD15+CD14+ cells leading to the suppression of T-cell proliferation. Conclusions G-CSF induces a population of ROS+ immunosuppressive CD15+CD14+ granulocytes. Strategies for how recombinant G-CSF can be scheduled to reduce effects on T-cell therapies should be developed in future clinical studies.

Abstract
Stem cell-based therapies raise hope for cell replacement and provide opportunity for cardiac regenerative medicine and tumor therapy. Extracellular vesicles are a membrane-enclosed intercellular delivery system with the potential to improve the therapeutic efficacy of the treatment of a variety of disorders. As the incidence of breast cancer continues to rise, radiotherapy has emerged as a leading treatment modality. Radiotherapy also increases the risk of coronary heart disease and cardiac mortality. In a chest-irradiated mouse model of cardiac injury, we investigated the effects of local irradiation. We found an increased lethality after 16 Gy irradiation. Importantly, radio-detoxified LPS (RD-LPS) treatment prolonged the survival significantly. By flow cytometry, we demonstrated that upon administration of RD-LPS, the number of bone marrow-derived endothelial progenitor cells increased in the bone marrow and, in particular, in the circulation. Furthermore, mass spectrometry analysis showed that RD-LPS altered the proteomic composition of bone marrow cell-derived small extracellular vesicles (sEVs). RD-LPS treatment increased interferon-induced transmembrane protein-3 (IFITM3) expression markedly both in bone marrow cells and in bone marrow cell-derived small extracellular vesicles. This is the first study to demonstrate that radio-detoxified LPS treatment induces an increase of circulating endothelial progenitor cells (EPCs) in parallel with a reduced radiotherapy-related mortality. While the total number of bone marrow-derived extracellular vesicles was significantly increased 24 h after treatment in the RD-LPS groups, the number of endothelial progenitor cells was reduced in animals injected with GW4896 (a chemical inhibitor of exosome biogenesis) as compared with controls. In contrast to these in vivo results, in vitro experiments did not support the effect of sEVs on EPCs. Our data raise the intriguing possibility that IFITM3 may serve as a marker of the radio-detoxified LPS treatment.

Abstract
Objective: To observe the efficacy and safety between Pegfilgrastim (PEG-rhG-CSF) and Recombinant human granulocyte colony stimulating factor (rhG-CSF) in hematological malignancy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: 157 patients after allo-HSCT were enrolled in this study from June 2015 to November 2016. Two agents of G-CSF were used to stimulate hematopoietic recovery after transplantation. There were 65 cases in PEG-rhG-CSF and 92 cases in rhG-CSF groups. Patients in PEG-rhG-CSF group were given a single subcutaneous dose of 6 mg on the first day and +8 d, while cases in rhG-CSF group were given in dose of 5 μg·kg(-1)·d(-1) by subcutaneous injection from +1 d continuing to neutrophils more than 1.5×10(9)/L, and then the indicators and survival rates in two groups after transplantation were compared. Results: ①There were no significant differences of the neutrophil implantation time[13.5 (8-12) d vs 13 (9-24) d, P=0.393] and platelet implantation time [14 (9-160) d vs 14 (9-92) d, P=0.094] between PEG-rhG-CSF and rhG-CSF groups respectively. There were no significant differences in terms of neutropenia period (P=0.435) , number of cases who got fever during neutropenia (P=0.622) , and the median time of fever in neutropenia period (P=0.460) , respectively between the two groups. There were no significant differences of erythrocyte and platelet transfusions (P=0.074, P=0.059) within 1 month after transplantation. ②There were no significant differences with regard to the incidences of acute GVHD[23.1% (15/65) vs 34.8% (32/92) , P=0.115], chronic GVHD[20.0% (13/65) vs 32.6% (32/92) , P=0.081], Ⅱ-Ⅳdegree of acute GVHD[30.0% (13/65) vs 30.4% (30/92) , P=0.287] and extensive chronic GVHD[9.2% (6/65) vs 20.7% (19/92) , P=0.135] between PEG-rhG-CSF and rhG-CSF groups. ③There were no significant differences in terms of disease free survival (DFS) (62.5% vs 61.4%, P=0.478) and overall survival (OS) (67.4% vs 67.3%, P=0.718) between PEG-rhG-CSF and rhG-CSF groups. ④There was no significant difference of the non-relapse mortality (NRM) between PEG-rhG-CSF and rhG-CSF groups[20.5% (95%CI 11.4%-37.0%) vs 32.6% (95%CI 22.2%-47.9%) , P=0.141]. The relapse rate was not statistically significant[14.9% (95%CI 7.4%-29.8%) vs 10.0% (95%CI 5.0%-20.0%) , P=0.299]. Conclusion: Compared with rhG-CSF, PEG-rhG-CSF could reduce the times of injection. There were no differences in terms of hematopoietic recovery, the incidence of GVHD, relapse rate, DFS and OS rates after allo-HSCT between two groups.

Filgrastim enhances T-cell clearance by antithymocyte globulin exposure after unrelated cord blood transplantation. Blood Adv 2019.

Abstract
Residual antithymocyte globulin (ATG; Thymoglobulin) exposure after allogeneic hematopoietic (stem) cell transplantation (HCT) delays CD4+ T-cell immune reconstitution (CD4+ IR), subsequently increasing morbidity and mortality. This effect seems particularly present after cord blood transplantation (CBT) compared to bone marrow transplantation (BMT). The reason for this is currently unknown. We investigated the effect of active-ATG exposure on CD4+ IR after BMT and CBT in 275 patients (CBT n = 155, BMT n = 120; median age, 7.8 years; range, 0.16-19.2 years) receiving their first allogeneic HCT between January 2008 and September 2016. Multivariate log-rank tests (with correction for covariates) revealed that CD4+ IR was faster after CBT than after BMT with <10 active-ATG × day/mL (P = .018) residual exposure. In contrast, >10 active-ATG × day/mL exposure severely impaired CD4+ IR after CBT (P < .001), but not after BMT (P = .74). To decipher these differences, we performed ATG-binding and ATG-cytotoxicity experiments using cord blood- and bone marrow graft-derived T-cell subsets, B cells, natural killer cells, and monocytes. No differences were observed. Nevertheless, a major covariate in our cohort was Filgrastim treatment (only given after CBT). We found that Filgrastim (granulocyte colony-stimulating factor [G-CSF]) exposure highly increased neutrophil-mediated ATG cytotoxicity (by 40-fold [0.5 vs 20%; P = .002]), which explained the enhanced T-cell clearance after CBT. These findings imply revision of the use (and/or timing) of G-CSF in patients with residual ATG exposure.

Abstract
The present review describes the biology of human leukocyte antigen haplotype mismatched ("haploidentical") transplantation, its translation to clinical practice to cure leukemia, and the results of current transplantation protocols. The 1990s saw what had been major drawbacks of haploidentical transplantation, ie, very strong host-versus-graft and graft-versus-host alloresponses, which led respectively to rejection and graft-versus-host disease (GVHD), being overcome through transplantation of a "mega-dose" of T cell-depleted peripheral blood hematopoietic progenitor cells and no posttransplant pharmacologic immunosuppression. The absence of posttransplant immunosuppression was an opportunity to discover natural killer cell alloreactions that eradicated acute myeloid leukemia and improved survival. Furthermore, it also unveiled the benefits of transplantation from mother donors, a likely consequence of the mother-to-child interaction during pregnancy. More recent transplantation protocols use unmanipulated (without ex vivo T-cell depletion) haploidentical grafts combined with enhanced posttransplant immunosuppression to help prevent GVHD. Unmanipulated grafts substantially extended the use of haploidentical transplantation with results than even rival those of matched hematopoietic transplantation. In T cell-depleted haploidentical transplantation, recent advances were made by the adoptive transfer of regulatory and conventional T cells.

Abstract
Allogeneic blood or bone-marrow transplantation (alloBMT) is a potentially curative treatment for a variety of haematological malignancies and nonmalignant diseases. Historically, human leukocyte antigen (HLA)-matched siblings have been the preferred source of donor cells owing to superior outcomes compared with alloBMT using other donors. Although only approximately one-third of patients have an HLA-matched sibling, nearly all patients have HLA-haploidentical related donors. Early studies using HLA-haploidentical alloBMT resulted in unacceptably high rates of graft rejection and graft-versus-host disease (GVHD), leading to high nonrelapse mortality and consequently poor survival. Several novel approaches to HLA-haploidentical alloBMT have yielded encouraging results with high rates of successful engraftment, effective GVHD control and favourable outcomes. In fact, outcomes of several retrospective comparative studies seem similar to those seen using other allograft sources, including those of HLA-matched-sibling alloBMT. In this Review, we provide an overview of the three most-developed approaches to HLA-haploidentical alloBMT: T-cell depletion with 'megadose' CD34(+) cells; granulocyte colony-stimulating factor-primed allografts combined with intensive pharmacological immunosuppression, including antithymocyte globulin; and high-dose, post-transplantation cyclophosphamide. We review the preclinical and biological data supporting each approach, results from major clinical studies, and completed or ongoing clinical studies comparing these approaches with other alloBMT platforms.

Abstract
Eighty adult patients with acute myeloid leukemia (AML) received peripheral blood T cell-replete HLA haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Disease status at transplantation was either first or second complete remission (CR, n = 69) or relapse/refractory (n = 11). Identical transplant-related procedures with conditioning regimen consisting of fractionated 800 cGy total body irradiation (TBI), fludarabine (30 mg/m(2)/day for 5 days), busulfan (3.2 mg/kg/day for 2 days), and antithymocyte globulin (1.25 mg/kg/day on days -4 to -1) and graft-versus-host disease (GVHD) prophylaxis with tacrolimus and methotrexate were used in all patients. Recovery of neutrophil (median, 11 days) and platelet (median, 10 days) counts was achieved in all patients with full donor chimerism (≥ 99%), and no delayed engraftment failure was observed. The cumulative incidence of grades III to IV acute GVHD and moderate to severe chronic GVHD was 11.2% and 26.3%, respectively. A donor CD8(+) and CD4(+) T cell dose above the median value was significantly associated with the incidences of grades II to IV acute GHVD and moderate to severe chronic GVHD, respectively. After a median follow-up of 28 months for survivors, the 2-year cumulative incidences of relapse (n = 20) and nonrelapse mortality (n = 10) were 26.6% and 12.2%, respectively. Although all but 1 patient in relapse/refractory status died, the 2-year overall and progression-free survival of patients in first CR was 82.5% and 75.1%, respectively. We suggest the strategy of fractionated 800 cGy TBI-based conditioning with unmanipulated peripheral blood stem cell grafts seems feasible with favorable outcomes for adult patients with AML undergoing haplo-HSCT in CR.

Abstract
The efficacy of allogeneic hematopoietic stem cell transplantation is counterbalanced by the occurrence of life-threatening immune-mediated complications, such as graft-versus-host disease (GVHD), a multistep disease which is reportedly fatal to approximately 15% of transplant recipients. It is now established that T-cell-dendritic cell interactions, T-cell activation, release of proinflammatory cytokines and T-cell trafficking partake in GVHD pathogenesis. This article will focus on the most recent strategies aimed at preventing/treating GVHD by manipulating components of the innate and adaptive immune response from both the donor and the host.

Abstract
Cytomegalovirus (CMV) infection and delayed immune reconstitution (IR) remain serious obstacles for successful haploidentical stem cell transplantation (haplo-SCT). CMV-specific IR varied according to whether patients received manipulated/unmanipulated grafts or myeloablative/reduced intensity conditioning. CMV infection commonly occurs following impaired IR of T cell and its subsets. Here, we discuss the factors that influence IR based on currently available evidence. Adoptive transfer of donor T cells to improve CMV-specific IR is discussed. One should choose grafts from CMV-positive donors for transplant into CMV-positive recipients (D+/R+) because this will result in better IR than would grafts from CMV-negative donors (D−/R+). Stem cell source and donor age are other important factors. Posttransplant complications, including graft-versus-host disease and CMV infection, as well as their associated treatments, should also be considered. The effects of varying degrees of HLA disparity and conditioning regimens are more controversial. As many of these factors and strategies are considered in the setting of haplo-SCT, it is anticipated that haplo-SCT will continue to advance, further expanding our understanding of IR and CMV infection.

Abstract
Invasive fungal diseases are increasingly important opportunistic infections that are intimately linked to immune-suppression in the context of cytotoxic treatment of neoplastic diseases, stem cell and solid-organ transplantation, and primary immune deficiencies. Mortality rates remain high despite the availability of novel antifungals that are both safe and highly active in vitro, suggesting that clinical outcomes may be improved through modulation of host immunity. Ongoing advances in our knowledge of fungal-host interactions facilitate rational design of novel immunotherapeutics. Thus, antifungal immunotherapy now includes age-old interventions such as granulocyte and immunoglobulin transfusions, as well as promising experimental techniques such as antifungal vaccines and adoptive immunotherapy. To realize the potential of these rapidly evolving technologies, transition from the bench to clinical-phase studies must occur at a more rapid pace.

Abstract
Abstract
We used a novel NF-08-TM transplant protocol based on intravenous busulfan, cyclophosphamide, fludarabine, and thiotepa in 82 consecutive patients with β-thalassemia major (TM), including 52 with allogeneic peripheral blood stem cell transplantation (PBSCT) from unrelated donors (UDs) with well-matched human leukocyte antigens and 30 with hematopoietic stem cell transplantation (HSCT) from matched sibling donors (MSDs). The median age at transplantation was 6.0 years (range, 0.6-15.0 years), and the ratio of male-to-female patients was 56:26. The median follow-up time was 24 months (range, 12-39 months). The estimated 3-year overall survival and TM-free survival were 92.3% and 90.4% in the UD-PBSCT group and 90.0% and 83.3% in the MSD-HSCT group. The cumulative incidences of graft rejection and grades III-IV acute graft-versus-host disease were 1.9% and 9.6%, respectively, in the UD-PBSCT group and 6.9% and 3.6%, respectively, in the MSD-HSCT group. The cumulative incidence of transplant-related mortality was 7.7% in the UD-PBSCT group and 10.0% in the MSD-HSCT group. In conclusion, UD-PBSCTs using the well-tolerated NF-08-TM protocol show similar results to MSD-HSCTs and can be used to treat β-thalassemia patients in the absence of MSDs.

Abstract
This study analysed the effects of growth factor on outcome after haematopoietic stem-cell transplantation (HSCT) with >9 years follow-up. Of 1887 adult patients with acute leukaemia who received bone marrow from human leucocyte antigen (HLA)-identical siblings and were treated with myeloablative conditioning, 459 (24%) were treated with growth factor. Growth factor hastened engraftment of neutrophils (P < 0·0001), but reduced platelet counts (P = 0·0002). Graft-versus-host disease (GVHD)-free survival (no acute GVHD grade II-IV or chronic GVHD) at 10 years was 12 ± 2% (±SE) in the growth factor group, as opposed to 17 ± 2% in the controls [hazard ratio (HR) 0·81, P = 0·001]. Similar differences in GVHD-free survival were seen in patients with or without conditioning with total body irradiation (TBI). Non-relapse mortality (NRM) was higher in the growth factor group irrespective of whether or not TBI conditioning was included [HR = 1·48; 95% confidence interval (CI): 1·15-1·9; P = 0·002; HR = 1·59; 95% CI: 1·07-2·37; P = 0·02, respectively]. Both groups had similar probabilities of leukaemic relapse (HR = 0·96; 95% CI: 0·78-1·18; P = 0·71). Leukaemia-free survival (LFS) at 10 years was 35 ± 2% in those receiving growth factor prophylaxis, as opposed to 44 ± 1% in the controls (HR = 0·70; 95% CI: 0·60-0·82; P = 0·00001). Prophylaxis with growth factor increases the risk of GVHD, does not affect relapse, increases NRM and reduces LFS > 10 years after HSCT, regardless of conditioning with TBI.

Abstract
For patients with hematologic malignancies at high risk of relapse who do not have matched donors, a suitable alternative stem cell source is the HLA-haploidentical 2 or 3-loci mismatched family donor who is readily available for nearly all patients. Transplantation across the major HLA barrier is associated with strong T-cell alloreactions, which were originally manifested as a high incidence of severe GVHD and graft rejection. The present review shows how these obstacles to successful transplantation were overcome in the last 15 years, making full haplotype-mismatched transplantation a clinical reality that provides similar outcomes to transplantation from matched unrelated donors. The review also discusses the advantages and drawbacks of current options for full haplotype-mismatched transplantation and highlights innovative approaches for re-building immunity after transplantation and improving survival.

Abstract
Studies of haploidentical hematopoietic stem cell transplantation (HSCT) have identified threshold doses of T cells below which severe GVHD is usually absent. However, little is known regarding optimal T-cell dosing as it relates to engraftment, immune reconstitution, and relapse. To begin to address this question, we developed a 2-step myeloablative approach to haploidentical HSCT in which 27 patients conditioned with total body irradiation (TBI) were given a fixed dose of donor T cells (HSCT step 1), followed by cyclophosphamide (CY) for T-cell tolerization. A CD34-selected HSC product (HSCT step 2) was infused after CY. A dose of 2 × 10(8)/kg of T cells resulted in consistent engraftment, immune reconstitution, and acceptable rates of GVHD. Cumulative incidences of grade III-IV GVHD, nonrelapse mortality (NRM), and relapse-related mortality were 7.4%, 22.2%, and 29.6%, respectively. With a follow-up of 28-56 months, the 3-year probability of overall survival for the whole cohort is 48% and 75% in patients without disease at HSCT. In the context of CY tolerization, a high, fixed dose of haploidentical T cells was associated with encouraging outcomes, especially in good-risk patients, and can serve as the basis for further exploration and optimization of this 2-step approach. This study is registered at www.clinicaltrials.gov as NCT00429143.

Abstract
The role of granulocyte-macrophage-colony-stimulating factor (GM-CSF) in the supportive care of cancer patients has been evaluated with promising results. More recently, GM-CSF has been added to regimens for the mobilization of hematopoietic progenitor cells. An expanding role for GM-CSF in regulating immune responses has been recognized based upon its activity on the development and maturation of antigen presenting cells and its capability for skewing the immune system toward Th1-type responses. GM-CSF has been shown to preferentially enhance both the numbers and activity of type 1 dendritic cells (DC1), the subsets of dendritic cells responsible for initiating cytotoxic immune responses. The increase in DC1 content and activity following local and systemic GM-CSF administration support a role for GM-CSF as an immune stimulant and vaccine adjuvant in cancer patients. GM-CSF has shown clinical activity as an immune stimulant in tumor cell and dendritic cell vaccines, and may increase antibody-dependent cellular cytotoxicity. The successful use of myeloid acting cytokines to enhance anti-tumor responses will likely require the utilization of GM-CSF in combination with cytotoxic or other targeted therapies.

Abstract
Hematopoietic cytokines have been used primarily as supportive care for patients undergoing cytotoxic chemotherapy or hematopoietic progenitor mobilization. Although the commonly used agents, granulocyte colony-stimulating factor and granulocytemacrophage colony-stimulating factor (GM-CSF), have been used interchangeably, it is clear that they have different effects on immune function and immune priming. GM-CSF has been used for some time as a vaccine adjuvant agent because of its activity on monocytes and dendritic cells. In order to capitalize on the immune activation effects of GM-CSF, numerous groups have transduced the GM-CSF gene into tumor cells in an effort to recruit local inflammatory cells and cytokines to the site of vaccination. Additionally, GM-CSF alone has been demonstrated to have activity for patients with high-risk melanoma and hormone-refractory prostate cancer. This article discusses some of the immune enhancing and suppressive activities of the hematopoietic cytokines, with particular focus on the immunomodulatory effects of GM-CSF, both in the context of single-agent therapy for solid tumors as well as in the context of dendritic cell modulation during therapy for hematopoietic malignancies.

Abstract
Interest in mismatched transplantation arises from the fact that a suitable one-haplotype mismatched donor is immediately available for virtually all patients, particularly for those who urgently need an allogenic transplant. Work on one haplotype-mismatched transplants has been proceeding for over 20 years all over the world and novel transplant techniques have been developed. Some centres have focused on the conditioning regimens and post transplant immune suppression; others have concentrated on manipulating the graft which may be a megadose of extensively T celldepleted or unmanipulated progenitor cells. Excellent engraftment rates are associated with a very low incidence of acute and chronic GVHD and regimen-related mortality even in patients who are over 50 years old. Overall, event-free survival and transplant-related mortality compare favourably with reports on transplants from sources of stem cells other than the matched sibling.

Abstract
Much progress has been made in the clinical, biological and technical aspects of the T-cell-depleted haploidentical hematopoietic stem cell transplantation (HSCT). Our experience demonstrates that infusing a megadose of extensively T-cell-depleted hematopoietic peripheral blood stem cells after an immuno-myeloablative conditioning regimen in acute leukemia patients ensures sustained engraftment with minimal GvHD without the need of any post-transplant immunosuppressive treatment. Since our first successful pilot study, our efforts have concentrated on developing new conditioning regimens, optimizing the graft processing and improving the post-transplant immunological recovery. The results we have so far achieved in high risk acute leukemia patients show that haploidentical transplantation is now a clinical reality. The present challenge is to reduce post-transplant infectious mortality and several strategies are being tested.

Abstract
Despite the availability of new antifungal compounds, morbidity and mortality of invasive fungal disease in allogeneic hematopoietic stem cell recipients are still unacceptably high. Over the past decade, one could witness an exciting improvement of the understanding of the molecular pathogenesis and of the complexity of host antifungal immune responses. This, in turn, provides critical information to augment host immunity against fungal pathogens. Strategies for enhancing the immune system include the administration of effector and regulatory cells (e.g., granulocytes, antigen-specific T cells, dendritic cells) as well as the administration of recombinant cytokines, interferons and growth factors (e.g., interferon-γ, keratinocyte growth factor, granulocyte- and granulocyte-macrophage colony stimulating factor). One has to recognize at the same time, however, that data of in vitro assays and animal models cannot necessarily be transferred into the clinical setting. In addition, meaningful clinical trials in allogeneic stem cell recipients suffering from invasive fungal disease require sufficiently large and homogenous cohorts of patients and can only be performed in international collaboration, but may ultimately improve the outcome of allogeneic transplant recipients with invasive fungal disease.

Abstract
BACKGROUND AIMS Granulocyte-macrophage (GM) colony-stimulating factor (CSF) has been used as an adjuvant in cancer immunotherapy. We tested the hypothesis that GM-CSF (Leukine(®); sargramostim) improves immune reconstitution after hematopoietic stem cell transplantation (HSCT) based on our prior in vitro work that demonstrated the pro-inflammatory effects of GM-CSF on dendritic cells (DC). METHODS GM-CSF was administered to donors, along with standard granulocyte (G) CSF, during stem cell mobilization, and to recipients from the day prior to transplant until engraftment. Eighteen patients consented to the GM-CSF(+) protocol and were compared with 17 matched controls undergoing HSCT during the same time period (GM-CSF(-)). RESULTS Numbers of white blood cells (WBC) and CD34(+) stem cells in the graft were comparable to controls. Surprisingly, contrary to our hypothesis, the allogeneic donor graft had significantly decreased numbers of CD3(+) T cells and their subsets (CD4(+), CD4(+) CD45RA(+), CD4(+) CD45RO(+), CD8(+) and CD8(+) CD45RO(+)), DC (both myeloid and plasmacytoid) and natural killer (NK) cells (CD16(+) CD56(+)). In the GM-CSF arm, following allogeneic transplantation, the levels of DC, T cells and NK cells did not increase with treatment. Conversely, autologous transplant patients receiving GM-CSF had a higher proportion of DC at the time of engraftment. CONCLUSIONS These findings demonstrate that administration of GM-CSF improves DC reconstitution after autologous rather than allogeneic HSCT.

Abstract
Advanced haematological malignancies are incurable without allogeneic haematopoietic SCT (HSCT). Many patients do not have a human leukocyte Ag (HLA)-matched donor; hence, haploidentical HSCT has been explored for some 20 years. Previous poor outcomes have improved recently with modifications, including the use of killer Ig-like receptor (KIR)-ligand-mismatched donors and highly T-cell-depleted megadose CD34+ stem cell infusions. Haploidentical HSCT was undertaken in 10 patients with heavily pretreated and advanced myeloid malignancies. Patient/donor pairs were KIR-ligand mismatched (GVL direction). Conditioning regimen was ATG, melphalan, fludarabine and thiotepa. G-CSF-mobilized PBSCs were CD34+ cell selected. No post transplant immunosuppression was given. Two patients died early; all others had sustained engraftment. Natural killer cell recovery, often to supranormal levels, occurred early, whereas CD4+ T-cell recovery was delayed. Acute GVHD occurred in three of eight (30%) patients, and chronic GVHD occurred in three of six (50%) evaluable patients. No infections with Candida or Aspergillus developed in seven patients receiving caspofungin prophylaxis. Three of 10 (30%) patients were alive and disease free at 10.1, 6 and 5.4 years post transplant (Karnovsky scores of 100%). In this heavily pretreated cohort with very advanced myeloid malignancies, KIR-ligand-mismatched haploidentical HSCT cured a significant proportion of patients.

Abstract
Background Pegylated granulocyte colony-stimulating factor (G-CSF; pegfilgrastim) is a longer-acting form of G-CSF, whose effects on dendritic cell (DC) and regulatory T cell (Treg) mobilization, and on the in vivo and ex vivo release of immune modulating cytokines remain unexplored. Methods Twelve patients with gynecological cancers received carboplatin/paclitaxel chemotherapy and single-dose pegfilgrastim as prophylaxis of febrile neutropenia. Peripheral blood was collected prior to pegfilgrastim administration (day 0) and on days +7, +11 and +21, to quantify immunoregulatory cytokines and to assess type 1 DC (DC1), type 2 DC (DC2) and Treg cell mobilization. In vitro-differentiated, monocyte-derived DC were used to investigate endocytic activity, expression of DC maturation antigens and ability to activate allogeneic T-cell proliferation. Results Pegfilgrastim increased the frequency of circulating DC1 and DC2 precursors. In contrast, CD4+FoxP3+ bona fide Treg cells were unchanged compared with baseline. Serum levels of hepatocyte growth factor and interleukin (IL)-12p40, but not transforming growth factor-β1 or immune suppressive kynurenines, significantly increased after pegfilgrastim administration. Interestingly, pegfilgrastim fostered in vitro monocytic secretion of IL-12p40 and IL-12p70 when compared with unconjugated G-CSF. Finally, DC populations differentiated in vitro after clinical provision of pegfilgrastim were phenotypically mature, possessed low endocytic activity, and incited a robust T-cell proliferative response. Conclusions Pegfilgrastim induced significant changes in immune cell number and function. The enhancement of monocytic IL-12 secretion portends favorable implications for pegfilgrastim administration to patients with cancer, a clinical context where the induction of immune deviation would be highly undesirable.

Abstract
Immune deficits account for the high frequency of life threatening bacterial, viral, and fungal opportunistic infections seen in allogeneic HSCT recipients. Despite advances in infectious disease management, the integrity of host defenses remains the mainstay of defense. The intensity of the preparative regimen, degree of HLA matching, source of stem cells (marrow, blood, or cord), extent of T-cell depletion, and immunosuppressive therapy are some of the factors that impact the kinetics, characteristics, and quality of immune reconstitution. Graft-versus-host disease and its prophylaxis or treatment produce a host environment that is particularly vulnerable to infections. Mucosal disruption and prolonged severe neutropenia usually confine their impact to the early course of transplant. After initial engraftment, HSCT recipients remain at great risk for opportunistic infections and this is related to prolonged and severe T-lymphocyte dysfunction of a complex multifactorial nature. B cell dysfunction is less problematic clinically, but includes deficiencies of immunoglobulin subclasses and impaired ability to mount a vaccine response. Advances in understanding of these immune deficits have resulted in successful strategies including revaccination, growth factors, thymic protection, and adoptive cellular therapy with antigen-specific cells.

Abstract
Recombinant human granulocyte colony-stimulating factor (G-CSF) has been in clinical use for approximately 2 decades. In healthy donors, it has been used to mobilize peripheral blood progenitor cells for hematopoietic stem cell transplantation and granulocytes for apheresis collection. In patients, it has been used to decrease the duration of neutropenia after chemotherapy and to offset the neutropenia due to myelodysplasia, acquired immunodeficiency syndrome, and genetic disorders of granulocyte production. As the number of uses of G-CSF in clinical practice grows, more side effects of this generally safe pharmaceutical agent are being recognized. Our objective in this article is to provide an in-depth review of the reported adverse events associated with the use of G-CSF.

Abstract
Hematopoietic SCT from a partially HLA-mismatched (HLA-haploidentical) first-degree relative offers the benefits of rapid and near universal donor availability but also the risks that result from traversing the HLA barrier; namely, graft failure, severe GVHD and prolonged immunodeficiency. Improvements over the last 10 years in conditioning regimens, graft engineering and pharmacological immunoprophylaxis of GVHD have substantially reduced the morbidity and mortality of HLA-haploidentical SCT. Highly immunosuppressive but nonmyeloablative conditioning extends the availability of HLA-haploidentical SCT to elderly hematologic malignancy patients lacking HLA-matched donors and permits recovery of autologous hematopoiesis in the event of graft failure. Current regimens for HLA-haploidentical SCT are associated with a 2-year non-relapse mortality of 20+/-5%, relapse of 35+/-15% and overall survival of 50+/-20%. Major developmental areas include harnessing natural killer cell alloreactivity to reduce the risk of disease relapse and improving immune reconstitution by delayed infusions of lymphocytes selectively depleted of alloreactive cells. Hematologic malignancy patients who lack suitably matched related or unrelated donors can now be treated with HLA-haploidentical related donor or unrelated umbilical cord blood SCT. Future clinical trials will assess the relative risks and benefits of these two graft sources.

Abstract
In this study, we have characterized reconstitution of the natural killer (NK) cell repertoire after haploidentical CD34(+) selected hematopoietic stem cell transplantation (HSCT) for high-risk hematologic malignancies. Analysis focused on alloreactive single-KIR(+) NK cells, which reportedly are potent antileukemic effectors. One month after HSCT, CD56(bright)/CD56(dim) NK-cell subsets showed inverted ratio and phenotypic features. CD25 and CD117 down-regulation on CD56(bright), and NKG2A and CD62L up-regulation on CD56(dim), suggest sequential CD56(bright)-to-CD56(dim) NK-cell maturation in vivo. Consistently, the functional potential of these maturation intermediates against leukemic blasts was impaired. Mature receptor repertoire reconstitution took at least 3 months. Importantly, at this time point, supposedly alloreactive, single-KIR(+) NK cells were not yet fully functional. Frequency of these cells was highly variable, independently from predicted NK alloreactivity, and below 1% of NK cells in 3 of 6 alloreactive patients studied. In line with these observations, no clinical benefit of predicted NK alloreactivity was observed in the total cohort of 56 patients. Our findings unravel the kinetics, and limits, of NK-cell differentiation from purified haploidentical hematopoietic stem cells in vivo, and suggest that NK-cell antileukemic potential could be best exploited by infusion of mature single-KIR(+) NK cells selected from an alloreactive donor.

Abstract
PURPOSE OF REVIEW The paper compares bone marrow and peripheral blood progenitor cell transplantations in the allogeneic setting. RECENT FINDINGS Peripheral blood progenitor cell use has emerged as an international standard of care for hematopoietic transplantation. These cells have a different cellular composition including higher numbers of CD34 cells and markedly higher numbers of T lymphocytes. Current data support the general safety of this approach for normal transplant donors. Results consistently indicate more rapid hematopoietic recovery compared with bone marrow transplantation. This may result in improved early survival in adults with high-risk leukemias, but longer follow-up has demonstrated an increased rate of chronic graft-versus-host disease morbidity and mortality which may obviate the long-term benefit. SUMMARY It is unclear whether peripheral blood progenitor cell or bone marrow transplantation will produce improved disease-free or overall survival. Additional studies with long-term follow-up are necessary to resolve these controversies.

Abstract
Autologous stem cell transplantation (ASCT) is the standard of care for patients with multiple myeloma (MM) younger than 70 years. However, despite this aggressive therapy most patients will still die of progressive disease. Recent reports have suggested that lymphocyte recovery is an important predictor of relapse or progressive disease in a number of hematologic malignancies including MM. We have conducted retrospective analysis of factors that could predict overall (OS) and progression free survival (PFS) in patients with MM who had ASCT. One hundred nineteen patients with multiple myeloma underwent ASCT. The median OS and PFS were 64 and 32 months, respectively. Univariate and multivariate analysis using Cox proportional hazards regression model showed that absolute lymphocyte count on day 30 following ASCT (ALC-30), international staging system (ISS) stage at diagnosis, and age at diagnosis significantly influenced OS and PFS following ASCT. OS (96 versus 48 months, P = .04) and PFS (43 versus 29 months, P = .03) following ASCT were higher in patients with ALC-30 >or=1.0 x 10(9)/L compared to patients ALC-30 <1.0 x 10(9)/L. Higher ALC-60, ALC-100, ALC-180, and ALC-365 did not predict superior OS and PFS. Patients with early-stage disease had significantly higher OS (ISS stages I, II, and III: 96, 53, and 29 months, respectively; P = .0023) and PFS (ISS stages I, II, and III: 55.5, 31, and 12 months, respectively; P = .027) compared to patients with advanced-stage disease at diagnosis. On univariate analysis, the type of initial chemotherapy (melphalan, VAD, PCAB), lymphocyte count on day of leukapheresis, and the lymphocyte dose infused (LY-DO) significantly influenced lymphocyte recovery following ASCT. Patients who received higher lymphocyte dose (LY-DO) >or=0.2 x 10(9)/kg had higher median ALC-15 (0.25 versus 0.19 x 10(9)/L; P = .3), ALC-30 (1.20 versus 0.99 x 10(9)/L; P = .08), ALC-60 (1.90 versus 1.01 x 10(9)/L; P = .013), ALC-100 (1.58 versus 1.03 x 10(9)/L; P = .016), and ALC-180 (1.33 versus 1.01 x 10(9)/L; P = .1), compared to patients who received LY-DO <0.2 x 10(9)/kg. In summary, our data suggest that infusing large numbers of lymphocytes improves lymphocyte recovery post-ASCT, and that higher ALC-30 is associated with better PFS and OS. These data suggest that a threshold number of CD34(+) cells should not be the only parameter considered for an adequate PBSC collection--perhaps a certain number of lymphocytes should be aimed for as well.

Abstract
Work on one haplotype-mismatched transplants has been proceeding for over 20 years all over the world and novel transplant techniques have been developed. Some centres have focused on the conditioning regimens and post transplant immune suppression; others have concentrated on manipulating the graft. Haploidentical transplant modalities are based mainly on high-intensity conditioning regimen, but reduced intensity regimens have recently been introduced. The graft may be a megadose of extensively T cell-depleted or unmanipulated progenitor cells. Excellent engraftment rates are associated with a very low incidence of GVHD- and regimen-related mortality even in patients who are over 50 years old. Overall, event-free survival and transplant-related mortality compare favourably with reports on transplants from sources of stem cells other than the matched sibling. Improvements will come with successful implementation of strategies to accelerate and strengthen post transplant immune reconstitution as well as transplantation of patients in early stage disease.

Abstract
OBJECTIVE Granulocyte colony-stimulating factor (G-CSF) is used to boost granulocyte counts in immunocompromised patients, but its effects on the immune system may be counterproductive. We tested the hypothesis that G-CSF-mobilized peripheral blood stem cell (PBSC) products are immunologically downregulated based on gene microarray analysis. METHODS Ten peripheral blood samples from normal donors for allogeneic PBSC transplantation were obtained before and after administration of G-CSF and tested on Affymetrix Human U133 Plus 2.0 GeneChip microarrays and by flow cytometry. Significant changes in gene expression after G-CSF were reported by controlling the false discovery rate at 5%. The quantitative real-time polymerase chain reaction method was used to validate expression of representative genes. RESULTS All immune cells measured, including neutrophils, monocytes, lymphocytes, and dendritic cells, were significantly increased after G-CSF. In terms of gene expression, inflammatory and neutrophil activation pathways were upregulated after G-CSF. However, adaptive immune-related gene expression, such as antigen presentation, co-stimulation, T-cell activation and cytolytic effector responses, were downregulated. CONCLUSION Despite significant increases in lymphocytes and antigen-presenting cells, G-CSF-mobilized PBSC allografts exhibit a suppressive adaptive immune-related gene-expression profile. However, innate and inflammatory responses are elevated. Our data provides an explanation for the potentially immunosuppressive effects observed after G-CSF administration.

Abstract
Much progress has been made in the clinical, biological and technical aspects of the T-cell-depleted full-haplotype mismatched transplants for acute leukaemia. Our experience demonstrates that infusing a megadose of extensively T-cell-depleted haematopoietic peripheral blood stem cells after an immuno-myeloablative conditioning regimen in acute leukaemia patients ensures sustained engraftment with minimal GvHD without the need of any post-transplant immunosuppressive treatment. Since our first successful pilot study, our efforts have concentrated on developing new conditioning regimens, optimising the graft processing and improving the post-transplant immunological recovery. The results we have so far achieved in more than 200 high-risk acute leukaemia patients show that haploidentical transplantation is now a clinical reality. Because virtually all patients have a mismatched family member, who is immediately available, mismatched transplantation should be offered as a viable option to high-risk acute leukaemia patients who do not have, or cannot find, a matched donor.

Abstract
In recent years, investigators have unraveled a previously unrecognized role for granulocyte colony-stimulating factor (G-CSF) in the regulation of T-cell and dendritic cell functions. The experimental evidence in favor of G-CSF-mediated immune regulation includes the ability to skew T-cell cytokine secretion to T-helper type 2 responses, and to promote regulatory T-cell and tolerogenic dendritic cell differentiation. Accordingly, beneficial effects of G-CSF have been detected in animal models of immune-mediated diseases, including posttransplantation graft-versus-host disease, experimental autoimmune encephalomyelitis, lupus nephritis, inflammatory bowel disease, and diabetes. The growing body of evidence supporting a novel role for G-CSF in the induction of T-cell tolerance is reviewed herein.

Abstract
OBJECTIVE We recently demonstrated that patients with high levels of circulating dendritic cells (DC) and interleukin (IL)-12 are associated with reduced cancer relapse after hematopoietic stem cell transplantation. Identifying a growth factor that can promote these immune functions may have beneficial anti-tumor effects. We investigated the hypothesis that granulocyte-macrophage colony-stimulating factor (GM-CSF) induces IL-12 production and polarizes T lymphocytes toward a proinflammatory response. MATERIALS AND METHODS Peripheral blood mononuclear cells (PBMC), T lymphocytes, and antigen-presenting cells (APC) were cultured with GM-CSF and compared with no growth factors (control), G-CSF, or both GM-CSF and G-CSF. Cells were matured with either lipopolysaccharide or lectin (phytohemagglutinin). Type 1 and type 2 cytokines were measured by enzyme-linked immunosorbent assay. Induction of allogeneic T-lymphocyte proliferation induced by GM-CSF-stimulated APC was measured by mixed lymphocyte reaction. DC were measured by flow cytometry. RESULTS Levels of type 1 (IL-12, interferon-gamma, tumor necrosis factor-alpha) cytokines increased while type 2 (IL-10 and IL-4) cytokines decreased after stimulation of PBMC, T lymphocytes, and APC with GM-CSF. APC treated with GM-CSF induced higher proliferation of allogeneic T cells. CD11c and CD123-positive DC proliferated after exposure to GM-CSF. Both subtypes of DC (DC1 and DC2) were increased by GM-CSF. CONCLUSIONS GM-CSF induces production of type 1 proinflammatory cytokines by human PBMC, T lymphocytes, and APC. Type 2 cytokines are downregulated by GM-CSF and proliferation of allogeneic T cells is increased. These results demonstrate the potential for GM-CSF as a clinical agent for immune stimulation.

Abstract
Hematopoietic stem-cell transplantation is associated with a profound immune deficiency manifested as an increased propensity to develop infections and probably also malignancies. Innate immunity, including epithelial barriers and phagocytes, typically recovers within weeks after grafting, and B-cell counts and CD8 T-cell counts recover within months. CD4 T-cell counts are low for years, and their recovery is particularly slow in older patients with poor thymic function. Therapies to improve immune function include vaccinations, immunoglobulins for recurrent infections, cytokines, and antigen-specific donor lymphocyte infusions.

Abstract
In sequential studies, we compared immune reconstitution following high-dose chemotherapy (HDT) and stem cell transplantation (SCT) using intact mobilized peripheral blood stem cell (PSC) in intermediate grade non-Hodgkin's lymphoma (NHL) patients and CD34(+), lineage-negative (Lin(-)), Thy-1(lo) (CD34(+)Lin(-)Thy-1(lo)) stem cells in low-grade NHL patients. Cytokine expression and cellular phenotype and function were used as the basis of comparison. Despite differences in cellular composition of the stem cell grafts, immune reconstitution in both groups was similar. Significantly higher levels of type 1- and 2-associated cytokine messenger ribonucleic acid (mRNA) were observed both prior to and following transplant in the peripheral blood (PB) of both cohorts as compared to normal individuals. Similar levels of interleukin (IL)-4, IL-10, interferon-gamma (IFN-gamma), and tumor necrosis factor-alpha (TNF-alpha) messenger ribonucleic acid (mRNA) were seen in PB mononuclear cells following transplant with either product. In contrast, patients receiving isolated CD34(+)Lin(-)Thy-1(lo) cells expressed significantly higher IL-2 levels at all times examined post-transplant. Despite the high levels of cytokine gene expression and rapid restoration to pretransplant levels of CD3 cell number by day 30, T cell function and CD4:CD8 and CD4(+)CD45RA:CD4(+)CD45RO(+) ratios were significantly depressed in both cohorts compared to normal donors, and significantly lower in patients transplanted with CD34(+)Lin(-)Thy-1(lo) compared to patients receiving an intact PSC product. These data suggest that the peripheral tolerance in patients receiving HDT and an autologous SCT occurs independent of graft composition, although immune function and CD4 recovery are better facilitated by transplantation of an intact product.

Repeated hematopoietic stem and progenitor cell mobilization without depletion of the bone marrow stem and progenitor cell pool in mice after repeated administration of recombinant murine G-CSF. Hum Immunol 2007; 68:368-74. [PMID: 17462504 DOI: 10.1016/j.humimm.2007.01.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2006] [Revised: 01/19/2007] [Accepted: 01/23/2007] [Indexed: 01/13/2023]
Abstract
Administration of recombinant-human G-CSF (rhG-CSF) is highly efficient in mobilizing hematopoietic stem and progenitor cells (HSC/HPC) from the bone marrow (BM) toward the peripheral blood. This study was designed to investigate whether repeated G-CSF-induced HSC/HPC mobilization in mice could lead to a depletion of the bone marrow HSC/HPC pool with subsequent loss of mobilizing capacity. To test this hypothesis Balb/c mice were treated with a maximum of 12 repeated 5-day cycles of either 10 microg rhG-CSF/day or 0.25 microg rmG-CSF/day. Repeated administration of rhG-CSF lead to strong inhibition of HSC/HPC mobilization toward the peripheral blood and spleen after >4 cycles because of the induction of anti-rhG-CSF antibodies. In contrast, after repeated administration of rmG-CSF, HSC/HPC mobilizing capacity remained intact for up to 12 cycles. The number of CFU-GM per femur did not significantly change for up to 12 cycles. We conclude that repeated administration of G-CSF does not lead to depletion of the bone marrow HSC/HPC pool.

Abstract
To understand how genes are distributed on chromosomes we bring new insights into gene positional clustering and its properties. We have made a large-scale analysis of three types of differentiation and we observed that genes that subsequently enter into different cell processes are positionally clustered on chromosomes. Genes from the clusters are transcribed subsequently with respect to time kinetics and also to position. This means that the genes related to a cellular process are clustered together, independent of the period of time during which they are active and important for the process. Our results also demonstrate not only that there are general regions of increased or decreased levels of gene expression, but also that, in fact, in some chromosome regions we can find clustering of genes related to specific cell processes. The results provided in this paper also support the theory of "transcription factories" and show that transcription of genes from the clusters is managed by softer epigenetic mechanisms.
