Abstract
Traumatic brain injury (TBI) is now characterized as a progressive, degenerative disease and continues to stand as a prevalent cause of death and disability. The pathophysiology of TBI is complex, with a variety of secondary cell death pathways occurring which may persist chronically following the initial cerebral insult. Current therapeutic options for TBI are minimal, with surgical intervention or rehabilitation therapy existing as the only viable treatments. Considering the success of stem-cell therapies in various other neurological diseases, their use has been proposed as a potential potent therapy for patients suffering TBI. Moreover, stem cells are highly amenable to adjunctive use with other therapies, providing an opportunity to overcome the inherent limitations of using a single therapeutic agent. Our research has verified this additive potential by demonstrating the efficacy of co-delivering human umbilical cord blood (hUCB) cells with granulocyte-colony stimulating factor (G-CSF) in a murine model of TBI, providing encouraging results which support the potential of this approach to treat patients suffering from TBI. These findings justify ongoing research toward uncovering the mechanisms which underlie the functional improvements exhibited by hUCB + G-CSF combination therapy, thereby facilitating its safe and effect transition into the clinic. This paper is a review article. Referred literature in this paper has been listed in the reference section. The datasets supporting the conclusions of this article are available online by searching various databases, including PubMed. Some original points in this article come from the laboratory practice in our research center and the authors’ experiences.

Peña ID, Borlongan CV. Translating G-CSF as an Adjunct Therapy to Stem Cell Transplantation for Stroke. Transl Stroke Res 2016; 6:421-9.

Abstract
Among recently investigated stroke therapies, stem cell treatment holds great promise by virtue of their putative ability to replace lost cells, promote endogenous neurogenesis,and produce behavioral and functional improvement through their "bystander effects." Translating stem cell in the clinic, however, presents a number of technical difficulties. A strategy suggested to enhance therapeutic utility of stem cells is combination therapy, i.e., co-transplantation of stem cells or adjunct treatment with pharmacological agents and substrates,which is assumed to produce more profound therapeutic benefits by circumventing limitations of individual treatments and facilitating complementary brain repair processes. We previously demonstrated enhanced functional effects of cotreatment with granulocyte-colony stimulating factor (GCSF)and human umbilical cord blood cell (hUCB) transplantation in animal models of traumatic brain injury (TBI). Here,we suggest that the aforementioned combination therapy may also produce synergistic effects in stroke. Accordingly, G-CSF treatment may reduce expression of pro-inflammatory cytokines and enhance neurogenesis rendering a receptive microenvironment for hUCB engraftment. Adjunct treatment of GCSF with hUCB may facilitate stemness maintenance and guide neural lineage commitment of hUCB cells. Moreover, regenerative mechanisms afforded by G-CSF-mobilized endogenous stem cells, secretion of growth factors by hUCB grafts and G-CSF-recruited endothelial progenitor cells(EPCs), as well as the potential graft–host integration that may promote synaptic circuitry re-establishment could altogether produce more pronounced functional improvement in stroked rats subjected to a combination G-CSF treatment and hUCB transplantation. Nevertheless, differences in pathology and repair processes underlying TBI and stroke deserve consideration when testing the effects of combinatorial G-CSF and hUCB cell transplantation for stroke treatment. Further studies are also required to determine the safety and efficacy of this intervention in both preclinical and clinical stroke studies.

Abstract
Acute myeloid leukaemia (AML) is a hierarchically structured malignancy in which aberrant leukemic stem cells drive the production of leukaemic blast cell clones. AML cells strictly depend on the bone marrow microenvironment (BMM) in which they reside. Classical AML cell cultures fail to mimic the BMM and, therefore, drug discovery studies are dominated by in vivo models. However, animal models are time consuming, labour intensive, provide limited mechanistic insight, and are unsuited for high-throughput studies, necessitating the development of novel AML models. The evolving ex vivo BMM-mimicking culture systems aim to fill this gap, with increasing success. Here, we discuss how AML-microenvironment co-culture models advance our understanding of this disease, and highlight their future potential for translational AML research.

Abstract
Traumatic brain injury (TBI), a major contributor to deaths and permanent disability worldwide, has been recently described as a progressive cell death process rather than an acute event. TBI pathophysiology is complicated and can be distinguished by the initial primary injury and the subsequent secondary injury that ensues days after the trauma. Therapeutic opportunities for TBI remain very limited with patients subjected to surgery or rehabilitation therapy. The efficacy of stem cell-based interventions, as well as neuroprotective agents in other neurological disorders of which pathologies overlap with TBI, indicates their potential as alternative TBI treatments. Furthermore, their therapeutic limitations may be augmented when combination therapy is pursued instead of using a single agent. Indeed, we demonstrated remarkable combined efficacy of human umbilical cord blood (hUCB) cell therapy and granulocyte-colony-stimulating factor (G-CSF) treatment in TBI models, providing essential evidence for the translation of this approach to treat TBI. Further studies are warranted to determine the mechanisms underlying therapeutic benefits exerted by hUCB + G-CSF in order to enhance its safety and efficacy in the clinic.

Abstract
It is well documented that specialized mesenchymal stem/stromal cells (MSCs) constitute the hematopoietic stem cell (HSC) niche in the bone marrow (BM), and these MSCs support/maintain the HSCs in an undifferentiated state. A number of studies have demonstrated that BM-derived MSCs (BM-MSCs) can support HSCs in vitro. However, it remains unclear whether nonhematopoietic tissue-derived MSC-like cells, such as dental pulp stem cells (DPSCs), have the ability to support HSCs. In this study, we prospectively isolated DPSCs from mouse mandibular incisors by fluorescence-activated cell sorting (FACS) using BM-MSC markers, such as PDGFRα and Sca-1. The PDGFRα and Sca-1 double-positive DPSCs and BM-MSCs showed similar morphologies and expression patterns of MSC markers. The ability of the DPSCs to support hematopoietic stem/progenitor cells (HSPCs) was then analyzed by an in vitro coculture system. Moreover, their HSC-supporting activity was evaluated by in vivo xenotransplantation assays using NOD/Shi-scid/IL-2Rγcnull (NOG) mice. Interestingly, the DPSCs supported human cord blood (CB)-derived CD34-positive (CD34+), as well as CD34-negative (CD34–), HSCs. The supporting activities of DPSCs for human CB-derived CD34+ and CD34– HSCs were comparable to those of BM-MSCs. The results of the present study demonstrated, for the first time, that prospectively isolated murine PDGFRα and Sca-1 double-positive DPSCs could support primitive human CD34+ and CD34– HSCs in vitro.

Abstract
Traumatic brain injury (TBI) is associated with neuro-inflammation, debilitating sensory-motor deficits, and learning and memory impairments. Cell-based therapies are currently being investigated in treating neurotrauma due to their ability to secrete neurotrophic factors and anti-inflammatory cytokines that can regulate the hostile milieu associated with chronic neuroinflammation found in TBI. In tandem, the stimulation and mobilization of endogenous stem/progenitor cells from the bone marrow through granulocyte colony stimulating factor (G-CSF) poses as an attractive therapeutic intervention for chronic TBI. Here, we tested the potential of a combined therapy of human umbilical cord blood cells (hUCB) and G-CSF at the acute stage of TBI to counteract the progressive secondary effects of chronic TBI using the controlled cortical impact model. Four different groups of adult Sprague Dawley rats were treated with saline alone, G-CSF+saline, hUCB+saline or hUCB+G-CSF, 7-days post CCI moderate TBI. Eight weeks after TBI, brains were harvested to analyze hippocampal cell loss, neuroinflammatory response, and neurogenesis by using immunohistochemical techniques. Results revealed that the rats exposed to TBI treated with saline exhibited widespread neuroinflammation, impaired endogenous neurogenesis in DG and SVZ, and severe hippocampal cell loss. hUCB monotherapy suppressed neuroinflammation, nearly normalized the neurogenesis, and reduced hippocampal cell loss compared to saline alone. G-CSF monotherapy produced partial and short-lived benefits characterized by low levels of neuroinflammation in striatum, DG, SVZ, and corpus callosum and fornix, a modest neurogenesis, and a moderate reduction of hippocampal cells loss. On the other hand, combined therapy of hUCB+G-CSF displayed synergistic effects that robustly dampened neuroinflammation, while enhancing endogenous neurogenesis and reducing hippocampal cell loss. Vigorous and long-lasting recovery of motor function accompanied the combined therapy, which was either moderately or short-lived in the monotherapy conditions. These results suggest that combined treatment rather than monotherapy appears optimal for abrogating histophalogical and motor impairments in chronic TBI.

Abstract
Effects of subcultivation of human bone marrow mesenchymal stem cells on their capacities for chondrogenesis and supporting hematopoiesis, and telomea length were investigated. Mesenchymal stem cells were isolated from human bone marrow aspirates and subcultivated several times at 37 degrees C under a 5% CO(2) atmosphere employing DMEM medium containing 10% FCS up to the 20th population doubling level (PDL). The ratio of CD45(-) CD105(+) cells among these cells slightly increased as PDL increased. However, there was no marked change in the chondrogenic capacity of these cells, which was confirmed by expression assay of aggrecan mRNA and Safranin O staining after pellet cell cultivation. The change in capacity to support hematopoiesis of cord blood cells was not observed among cells with various PDLs. On the other hand, telomere length markedly decreased as PDL increased at a higher rate than that at which telomere length of primary mesenchymal stem cells decreased as the age of donor increased.

Abstract
To examine whether serum obtained from bone marrow-transplanted mice can selectively expand hematopoietic stem cells (HSCs) among whole bone marrow cells in vitro, whole bone marrow cells were cultured with or without MS-5 murine stromal cells in the presence of serum obtained from transplanted mice on day 3 (day 3 serum) or serum from normal mice for 7 days. When whole bone marrow cells and MS-5 cells were co-cultured in day 3 serum for 7 days, the c-kit-positive, Sca-1-positive, lineage marker-negative cells (KSL cells) expanded approximately 25 times; however, when they were co-cultured in normal serum for 7 days, the KSL cells expanded approximately 1.3 times. Direct contact between the whole bone marrow cells and MS-5 cells was essential for expansion of KSL cells in the co-culture, and it upregulated the expression of some cytokines in MS-5. Above all, the day 3 serum specifically upregulated the expression of SCF, SDF-1 alpha, G-CSF, IL-11 and IL-6 in MS-5. The level of testosterone in the day 3 serum was higher than normal serum and the addition of the testosterone in the culture expanded the KSL cells among whole bone marrow cells on MS-5 cells and also upregulated the expression of SDF-1 alpha, IL-11 and IL-6 in MS-5. These data indicates that the serum of bone marrow-transplanted mice contains a factor(s) that induced changes in the expression levels of various cytokines in MS-5 stromal cells and enabled the MS-5 cells to expand the KSL cells among whole bone marrow cells.

Abstract
CD45 is a hematopoietic lineage-restricted antigen that is expressed on all hematopoietic cells except for some mature cell types. Cells expressing CD45 and CD34 but lacking CD38 and lineage antigens (CD45+CD34+CD38-Lin- cells) are well-documented hematopoietic stem cells (HSCs), and CD45+CD34-CD38-Lin- cells are probably less mature HSCs. In myelodysplastic syndromes (MDS), the malignant transformation site is a matter of debate, and CD45+CD34+CD38-Lin- HSCs were recently reported to be clonal. In the study reported here, we detected CD45-CD34-CD38-Lin- cells in the peripheral blood and bone marrow of patients with MDS and isolated them by successive application of density centrifugation, magnetic cell sorting, and fluorescence-activated cell sorting. Fluorescence in situ hybridization showed that CD45-CD34-CD38-Lin- cells had the same chromosomal aberration as the myeloblasts. In addition to CD45- and CD34-, they lacked CD117 and CD133 expression. Generally, MDS cells have extremely reduced hematopoietic potential compared with normal hematopoietic cells, but we documented the following in some patients. Freshly isolated CD45-CD34-CD38-Lin- cells did not form any hematopoietic colonies but had long-term culture-initiating cell activity. When cocultured with stroma cells, CD45-CD34-CD38-Lin- cells showed only weak potential for proliferation and differentiation, yet they differentiated into CD34+ cells and then mature myeloid cells. This newly identified cell population represents the most immature immunophenotype so far identified in the hematopoietic lineage and is involved in the malignant clone in MDS.

Abstract
The cell processing engineering for ex vivo expansion of hematopoietic cells is reviewed. All hematopoietic cells of different lineages and/or at various stages of differentiation are derived from the same precursor, pluripotent hematopoietic stem cells. Bone marrow stromal cells promote and regulate the self-renewal, commitment, differentiation, and proliferation of stem cells and progenitors through their secreted extracellular matrices and cytokine environment in the hematopoietic microenvironment. Although stroma-mediated hematopoiesis has been studied in vitro using the Dexter culture system in tissue culture flasks, hematopoiesis in the Dexter culture system is almost limited to a granulocyte lineage and the system could not expand primitive cells. The addition of large amounts of cytokines to the culture of hematopoietic cells enabled their expansion, but is too expensive. Some clonal stromal cell lines have been established from the Dexter culture of murine bone marrow cells in order to simplify and stimulate the ex vivo expansion of hematopoietic cells. In order to solve the problem regarding the usage of exogeneic stromal cell lines, a novel membrane-separated coculture system, in which stromal cells adhere onto the lower surface of a porous membrane and hematopoietic cells are incubated on the upper surface of the membrane, was proposed. In order to mimic the contact between stromal and hematopoietic cells in vivo in the bone marrow, several types of three-dimensional (3-D) culture of hematopoietic cells were developed. The 3-D coculture of hematopoietic cells with spatial development of stromal cells in nonwoven fabrics enabled the expansion of progenitors without cytokine addition. Progenitors in cord blood mononucleated cells were also successfully expanded without the addition in the 3-D coculture with primary human bone marrow stromal cells in 3-D. Heparin addition to the 3-D coculture and coating the nonwoven fabrics with N-(O-beta-(6-O-sulfogalactopyranosyl)-6-oxyhexyl)-3,5-bis(dodecyloxy)-benzamide further increased the number of progenitors.

Abstract
Migration and successive homing of haematopoietic stem/progenitor cells (HS/PCs) into haematopoietic microenvironments are critical to their proliferation and differentiation. To investigate molecular mechanisms underlying HS/PC migration, we used a human erythroleukaemia (HEL) cell line which has been characterized as a haematopoietic progenitor cell line and displays high migratory properties underneath the haematopoietic-supportive stromal cell line, HESS-M28. HEL cell migration is mediated by the adhesion of the CD29 integrin on HEL cells to HESS-28 cells which leads to the localization of filamentous actin and formation of cell polarity at membrane protrusions via actin cytoskeleton reorganization. HEL cell migration is inhibited by both dominant negative forms of the Rho-GTPase family members and a cell permeable inhibitor of LIMK1, S3 peptide. Expression of constitutively active- or inactive-forms of cofilin also inhibits HEL cell migration and phosphorylated cofilin is localized to the front protrusions of HEL cells. These results suggest that cytoskeleton reorganization mediated by a Rho-GTPase/LIMK1/cofilin pathway plays a critical role in the migration of HEL cells underneath HESS-M28 cells.

Abstract
BACKGROUND The in vivo hematopoietic microenvironment is composed of stromal cells and extracellular matrix in a 3D configuration. We have created a 3D microenvironment in vitro, employing spatial development of stromal cells in a nonwoven fabric porous carrier, Fibra-cel (FC). We compared its performance with that of a 2D microenvironment. METHODS Primary murine BM cells were inoculated on the layers of stromal cells prepared in FC (3D) or on a dish (2D) and cultured for 7-21 days. The hematopoietic cells harvested from the cultures were evaluated by colony-forming unit (CFU) assay and transplantation to sub lethally irradiated mice. RESULTS The maximum stromal cell concentration in the 2D culture was higher than that in the 3D culture. However, the hematopoietic cell concentration in the 3D culture was kept at a higher level than that in the 2D culture. The number of CFU-mix increased five times during 3D cultivation, but decreased in the 2D culture. The engraftment percentage of 3D cultured cells was comparable with that of fresh cells, and markedly higher than that of 2D cultured cells. DISCUSSION The 3D culture constructed with FC and stromal cells was clearly superior to 2D culture because hematopoietic progenitor cells were expanded without the addition of cytokines and the content of hematopoietic stem cells was maintained.

Abstract
Since dendritic cells (DC) play pivotal roles in both innate and adaptive immunity, DC can be a good target for immuno-gene therapy. However, the optimal generation method for gene-modified DC has not yet been well exploited. CD34+ cells from cord blood (CB), bone marrow (BM), or peripheral blood (PB) were expanded in a medium containing stem cell factor (SCF), flt 3 ligand (Flt3L) and thrombopoietin (TPO) with or without HESS-5, a murine BM stromal cell line, for 2 weeks (the first expansion step), then differentiated to DC in a medium containing granulocyte-macrophage colony-stimulating factor (GM-CSF), flt 3 ligand (Flt3L), stem cell factor (SCF), tumor necrosis factor-alpha (TNF-alpha), IL-4, and lipopolysaccharide (LPS) for 9 days (the second differentiation step). DC progenitors were transduced with human immunodeficiency virus (HIV) vectors at different time points during the second step. Use of HESS-5 during the first step resulted in more DC generation than without it (cell expansion: CB, 10,461 vs. 354-fold; BM, 962 vs. 225-fold; peripheral blood mononuclear cell (PBMC), 8,506 vs. 240-fold; %DC: CB, 83.4% vs. 76.9%; BM, 83.6 vs. 69.8%; PBMC, 85.9 vs. 60.5%). Gene transduction to the in vitro expanded DC progenitors at day 3 during the second step, resulted in better final yield of the gene-modified DC than that to those at day 0 or day 6 (as much as 44% of DC expressed green fluorescence protein (GFP) as a transgene) and the transduction efficiency correlated with endocytic ability and percent of S phase. DC transduced with an HIV vector encoding a melanoma antigen, MART-1, were adequately recognized by specific anti-MART-1 CTL. The two-step culture method with HESS-5 is useful for rapid expansion of DC progenitors and subsequent lentiviral gene transduction to DC.

Abstract
The ex vivo expansion of hematopoietic cells is one of the most challenging fields in cell culture. This is a rapidly growing area of tissue engineering with many potential applications in bone marrow transplantation, transfusion medicine or gene therapy. Over the last few years much progress has been made in understanding hematopoietic differentiation, discovery of cytokines, isolation and identification of cellular subtypes and in the development of a variety of bioreactor concepts. All this has led to a number of (preliminary) clinical trials that gave a hint of the benefits that can be obtained from the use of expanded hematopoietic cells in therapy. Moreover, as we understand the complexity and the regulation of hematopoiesis, it becomes obvious that highly sophisticated cultivation techniques and bioreactor concepts are needed: a new challenge for bioprocess engineering in cell culture.

Abstract
OBJECTIVE The hematopoietic microenvironment is complex, and the role of myofibroblast in its function is crucial. In order to obtain a stable model reflecting this particular cell type, we have previously established human bone marrow cell lines from primary myofibroblastic Stro1(+) population (pStro1(+)). We placed HPV16 E6 and E7 expression under the control of different promoters. Here, we have characterized and studied the hematopoietic support for two cell lines corresponding to the promoters alpha-SM (alphaSM-56 line) and SV40 (SV40-56 line). MATERIALS AND METHODS The expression profile was analyzed at the RNA level by gene array and at the protein level by Western blot, flow cytometry, and ELISA. Hematopoietic support determined using colony-forming unit (CFU) and stroma-adherent colony-forming cell (SA-CFC) assays. RESULTS The phenotype of cell lines was not significantly modified compared with primary myofibroblastic cells. They secreted a broad spectrum of hematopoietic cytokines and nonspecific mediators. The two lines allowed the growth of hematopoietic precursors and had different support capabilities. CONCLUSIONS We have extensively characterized two novel human bone marrow stromal cell lines. They retained a myofibroblastic phenotype and have substantial but different hematopoietic support capabilities. These lines provided a basis for determining stromal factors involved in stem-cell regulation.

Abstract
To clarify what kinds of cytokines are actually contributing to proliferation of hemopoietic stem cells in vivo after lethal irradiation, we have investigated the expression of some cytokines by RT-PCR method. Above all, expression of the SCF was increased significantly in the bone marrow cells soon after lethal irradiation in both the Sca-1 (+) bone marrow cells injected and non-injected mice. The day 6 serum from the lethally irradiated mice could support the proliferation of the Sca-1 (+) bone marrow cells, even though the serum from normal mice could not. The quantification analyses have revealed the increase of the amounts of IL-6 and flt3-ligand in their serum, but not significant increase of the amount of SCF. Precise PCR analysis has revealed that the cell surface associated form of SCF was significantly induced in the bone marrow after lethal irradiation. These data indicate that the cell surface form of SCF mainly promotes the proliferation of hemopoietic stem cells with some soluble cytokines under sever lack of hemopoietic stem cells in vivo caused by lethal irradiation and also suggest the importance of direct cell-to-cell interaction on proliferation of hematopoietic stem cells in vivo.

Abstract
A novel murine stromal cell line, HESS-M28, was established, which supports the expansion of human CD34+CD38- cells more than 300-fold in vitro in the presence of human IL-3 and SCF. These cells were used in an attempt to evaluate cis-acting elements of retroviral vectors in human primitive hematopoietic cells. Cord blood cells were cultured on top of the mixed cell layers of the stromal cell line, HESS-M28, and retroviral vector-producing cells. The FMEV-type vector SF/Lyt contained the spleen focus-forming virus U3 and the MESV primer-binding site (PBS), while MO3/Lyt contained the U3 region and PBS from Mo-MuLV. After transduction by the FMEV-type and Mo-MuLV-based vectors, expression of the marker gene murine CD8 (mCD8) was examined in CD34-, CD34+, and CD34+CD38- cells. In CD34+ and CD34+CD38- cells, expression of mCD8 was higher with the FMEV-type vector, SF/Lyt, compared with the cells transduced by the Mo-MuLV-based vector MO3/Lyt, although the expression was comparable in CD34- cells. Expression of marker genes was also confirmed in long-term culture-initiating cells (LTC-ICs) and SCID-repopulating cells (SRCs).
