Abstract
BACKGROUND Neuroblastoma is a common solid malignant tumor in children. Despite the development of new treatment options, the prognosis of high-risk neuroblastoma patients is still poor. High-dose chemotherapy and hematopoietic stem cell (HSC) transplantation might improve survival of patients with refractory neuroblastoma. In this study, we aimed to summarize the efficacy of autologous or allogeneic HSC transplantation combined with high-dose chemotherapy for patients with refractory neuroblastoma through the meta-analysis. METHODS AND ANALYSIS Relevant clinical trials of autologous or allogeneic HSC transplantation for the treatment refractory neuroblastoma patients will be searched in Web of Science, Cochrane Library, PubMed, Google Scholar, Embase, Medline, China National Knowledge Infrastructure, China Scientific Journal Database, Chinese Biomedical Literature Database and Wanfang Database from their inception to December 2020. Two researchers will perform data extraction and risk of bias assessment independently. The clinical outcomes including tumor response, overall survival, event-free survival (EFS), quality of life (QoL) and adverse events, were systematically evaluated by using Review Manager 5.3 and Stata 14.0 statistical software. RESULTS The results of this study will provide high-quality evidence for the effect of autologous or allogeneic HSC transplantation combined with high-dose chemotherapy on tumor response, survival, and QoL in patients with refractory neuroblastoma. CONCLUSIONS The conclusions of this meta-analysis will be published in a peer-reviewed journal, and provide more evidence-based guidance in clinical practice.

Abstract
Anaemia is one of the leading causes of disability in young adults and is associated with increased morbidity and mortality in elderly. With a global target to reduce the disease burden of anaemia, recent researches focus on novel compounds with the ability to induce erythropoiesis and regulate iron homeostasis. We aimed to explore the biological events and potential polypharmacological effects of water-extracted olive leaf (WOL) on human bone marrow-derived haematopoietic stem cells (hHSCs) using a comprehensive gene expression analysis. HPLC analysis identifies six bioactive polyphenols in the WOL. Treatment with WOL for 12 days regulated gene expressions related to erythroid differentiation, oxygen homeostasis, iron homeostasis, haem metabolism and Hb biosynthesis in hHSCs. Functional clustering analysis reveals several major functions of WOL such as ribosomal biogenesis and mitochondrial translation machinery, glycolytic process, ATP biosynthesis and immune response. Additionally, the colonies of both primitive and mature erythroid progenitors, CFU-E and BFU-E, were significantly increased in WOL-treated hHSCs. The expressions of erythroid markers, CD47, glycophorin A (GYPA), and transferrin receptor (TFRC) and adult Hb subunits-HBA and HBB were also confirmed in immunofluorescent staining and flow cytometer analysis in WOL-treated hHSCs. It is well known that induction of lineage-specific differentiation, as well as the maturation of early haematopoietic precursors into fully mature erythrocytes, involves multiple simultaneous biological events and complex signalling networks. In this regard, our genome-wide transcriptome profiling with microarray study on WOL-treated hHSCs provides general insights into the multitarget prophylactic and/or therapeutic potential of WOL in anaemia and other haematological disorders.

Abstract
Considerable efforts have been made in recent years in understanding the mechanisms that govern hematopoietic stem cell (HSC) origin, development, differentiation, self-renewal, aging, trafficking, plasticity and transdifferentiation. Hematopoiesis occurs in sequential waves in distinct anatomical locations during development and these shifts in location are accompanied by changes in the functional status of the stem cells and reflect the changing needs of the developing organism. HSCs make a choice of either self-renewal or committing to differentiation. The balance between self-renewal and differentiation is considered to be critical to the maintenance of stem cell numbers. It is still under debate if HSC can rejuvenate infinitely or if they do not possess ''true" self-renewal and undergo replicative senescence such as any other somatic cell. Gene therapy applications that target HSCs offer a great potential for the treatment of hematologic and immunologic diseases. However, the clinical success has been limited by many factors. This review is intended to summarize the recent advances made in the human HSC field, and will review the hematopoietic stem cell from definition through development to clinical applications.

Abstract
The hematopoietic syndrome represents the first therapeutic challenge following exposure to high doses of ionizing radiation. Today there is a crucial need to identify/develop new treatments in order to reach the transplantation threshold. The authors propose the concept of a global niche therapy strategy based on local and short-term secretion of selected morphogenes to favor a vascular niche in order to raise the transplantation threshold regeneration and to stimulate residual hematopoietic stem and progenitor cells. The present study was aimed at setting up a monkey model of gene therapy using Sonic hedgehog (Shh) as a first candidate. Multipotent mesenchymal stem cells from adipocyte tissues were nucleofected with mock and Sonic hedgehog pIRES2 plasmids using Amaxa technology. 8-Gy gamma irradiated monkeys were given a single intraosseous injection of manipulated or unmanipulated adipocyte stem cells 48 h following total body irradiation. Mock and Shh-grafts were well tolerated. This preliminary study establishes the feasibility of transient gene therapy in highly irradiated monkeys. Ongoing studies will determine the putative efficacy of this therapeutic strategy.

Abstract
Background Sall4 is a key factor for the maintenance of pluripotency and self-renewal of embryonic stem cells (ESCs). Our previous studies have shown that Sall4 is a robust stimulator for human hematopoietic stem and progenitor cell (HSC/HPC) expansion. The purpose of the current study is to further evaluate how Sall4 may affect HSC/HPC activities in a murine system. Methods Lentiviral vectors expressing Sall4A or Sall4B isoform were used to transduce mouse bone marrow Lin-/Sca1+/c-Kit+ (LSK) cells and HSC/HPC self-renewal and differentiation were evaluated. Results Forced expression of Sall4 isoforms led to sustained ex vivo proliferation of LSK cells. In addition, Sall4 expanded HSC/HPCs exhibited increased in vivo repopulating abilities after bone marrow transplantation. These activities were associated with dramatic upregulation of multiple HSC/HPC regulatory genes including HoxB4, Notch1, Bmi1, Runx1, Meis1 and Nf-ya. Consistently, downregulation of endogenous Sall4 expression led to reduced LSK cell proliferation and accelerated cell differentiation. Moreover, in myeloid progenitor cells (32D), overexpression of Sall4 isoforms inhibited granulocytic differentiation and permitted expansion of undifferentiated cells with defined cytokines, consistent with the known functions of Sall4 in the ES cell system. Conclusion Sall4 is a potent regulator for HSC/HPC self-renewal, likely by increasing self-renewal activity and inhibiting differentiation. Our work provides further support that Sall4 manipulation may be a new model for expanding clinically transplantable stem cells.

Abstract
PURPOSE To evaluate and compare the presence of cytokines and growth factors in both bone marrow (BM) and peripheral blood. MATERIAL Samples of autogenous BM aspirate and peripheral blood (PB) from 7 patients ranging in age from 49 to 80 years were analyzed with real-time polymerase chain reaction technology to identify and compare selected gene expression for specific cytokines and growth factors. The genes selected for analysis included those involved in osteogenesis, hematogenesis, angiogenesis, extracellular matrix molecules, and cell-adhesion molecules. A maximum of 4 cc';s BM aspirate was taken from the anterior iliac crest and 0.5 mL of venous blood was drawn from each of 7 patients. RESULTS The results of the analysis indicate that both circulating blood and BM aspirate contain large quantities of a host of growth factors and cytokines. More platelet-derived growth factor is expressed in patient blood (PB) than in BM. Vascular endothelial growth factor alpha is expressed slightly greater in BM and vascular endothelial growth factor beta is slightly more prominent in PB. Transforming growth factors (TGFs) TGFA, TGFB1, and TGFB3 were equally expressed in BM and PB, and TGFB2 had a greater expression in PB. Bone morphogenetic proteins (BMPs) 1, 3, 7, 8B, R1A, and PR2 were almost equally expressed in BM and PB. BMPs 4 and 6 were expressed greater in PB. BMP2 was expressed more in BM. Extracellular matrix factors were equally expressed in PB and BM. Mesenchymal stem cell lineage markers varied in PB and BMA, and hematopoietic stem cell lineage markers were expressed more in PB than BM. Gene expression for angiogenic factors were equally expressed in PB and BM. CONCLUSION In this investigation, specific cytokines and growth factors in BM are compared with those in peripheral blood. Each has similar biologic effects and most expressed equally in BM and PB. However, BMP2 and vascular endothelial growth factor alpha had greater expression in BM.

Abstract
It has long been known that lymphopoiesis is transiently suppressed during pregnancy, which can be experimentally simulated by estrogen treatment. We now confirm with Rag1/GFP reporter mice that early lymphoid progenitors in the lineage marker(-) c-kit(high) ScaI(+), hematopoietic stem cell-enriched fraction of bone marrow are particularly depressed in these circumstances. Hematopoietic and environmental cells are both potential hormone targets and, because of this complexity, very little is known regarding mechanisms. We have now identified soluble Frizzled-related protein (sFRP)1 as an estrogen-inducible gene in stromal cells, whose expression corresponded to inability to support lymphopoiesis. Bone-lining stromal cells express sFRP1, and the transcripts were elevated by pregnancy or estrogen injection. Estrogen receptor-alpha was essential for both lymphoid suppression and induction of the sFRP family. SFRP1 has been mainly described as an antagonist for complex Wnt signals. However, we found that sFRP1, like Wnt3a, stabilized beta-catenin and blocked early lymphoid progression. Myeloerythroid progenitors were less affected by sFRP1 in culture, which was similar to estrogen with respect to lineage specificity. Hematopoietic stem cells expressed various Frizzled receptors, which markedly declined as they differentiated to lymphoid lineage. Thus, hormonal control of early lymphopoiesis in adults might partly relate to sFRP1 levels.

Abstract
Human embryonic stem cells (hESCs) represent a unique population of cells capable of self-renewal and differentiation into all types of somatic cells, including hematopoietic and endothelial cells. Since the pattern of hematopoietic and endothelial development observed in the embryo can be reproduced using ESCs differentiated in culture, hESCs can be used as a model for studies of specification and diversification of hematoendothelial progenitors. In addition, hESCs can be seen as a scalable source of hematopoietic and endothelial cells for in vitro studies. This unit describes a method for efficient differentiation of hESCs into hematopoietic progenitors and endothelial cells through coculture with mouse OP9 bone marrow stromal cells, as well as an approach for their analysis and isolation. Support protocols are provided for culture of mouse embryonic fibroblasts, evaluation of hematopoietic and endothelial differentiation by flow cytometry and colony-forming assay, removal of OP9 cells, and propagation of hESC-derived endothelial cells.

Abstract
Human myeloid leukemias provide models of maturation arrest and differentiation therapy of cancer. The genetic lesions of leukemia result in a block of differentiation (maturation arrest) that allows myeloid leukemic cells to continue to proliferate and/or prevents the terminal differentiation and apoptosis seen in normal white blood cells. In chronic myeloid leukemia, the bcr-abl (t9/22) translocation produces a fusion product that is an activated tyrosine kinase resulting in constitutive activation cells at the myelocyte level. This activation may be inhibited by imatinib mesylate (Gleevec, STI-571), which blocks the binding of ATP to the activated tyrosine kinase, prevents phosphorylation, and allows the leukemic cells to differentiate and undergo apoptosis. In acute promyelocytic leukemia, fusion of the retinoic acid receptor-alpha with the gene coding for promyelocytic protein, the PML-RAR alpha (t15:17) translocation, produces a fusion product that blocks the activity of the promyelocytic protein, which is required for formation of the granules of promyelocytes and prevents further differentiation. Retinoic acids bind to the retinoic acid receptor (RAR alpha) component of the fusion product, resulting in degradation of the fusion protein by ubiquitinization. This allows normal PML to participate in granule formation and differentiation of the promyelocytes. In one common type of acute myeloid leukemia, which results in maturation arrest at the myeloid precursor level, there is a mutation of FLT3, a transmembrane tyrosine kinase, which results in constitutive activation of the IL-3 receptor. This may be blocked by agents that inhibit farnesyl transferase. In each of these examples, specific inhibition of the genetically altered activation molecules of the leukemic cells allows the leukemic cells to differentiate and die. Because acute myeloid leukemias usually have mutation of more than one gene, combinations of specific inhibitors that act on the effects of different specific genetic lesions promises to result in more effective and permanent treatment.

Abstract
Lymphocyte production in bone marrow (BM) requires substantial cell division, but the relationship between largely quiescent stem cells and dividing lymphoid progenitors is poorly understood. Therefore, the proliferation and cell cycle status of murine hematopoietic progenitors that have just initiated the lymphoid differentiation program represented the focus of this study. Continuous bromo-2'-deoxyuridine (BrdU) incorporation and DNA/RNA analysis by flow cytometry revealed that a surprisingly large fraction of RAG-1(+)c-kit(hi) early lymphoid progenitors (ELPs) and RAG-1(+)c-kit(lo) pro-lymphocytes (Pro-Ls) in adult BM were in cell cycle quiescence. In contrast, their counterparts in 14-day fetal liver actively proliferated. Indeed, the growth fraction (cells in G(1)-S-G(2)-M phases) of fetal ELPs was on average 80% versus only 30% for adult ELPs. After 5-fluorouracil treatment, as many as 60% of the adult ELP-enriched population was in G(1)-S-G(2)-M and 34% incorporated BrdU in 6 hours. Transcripts for Bcl-2, p21Cip1/Waf1, and p27 Kip1 cell cycle regulatory genes correlated inversely well with proliferative activity. Interestingly, adult lymphoid progenitors in rebound had the high potential for B lymphopoiesis in culture typical of their fetal counterparts. Thus, lymphocyte production is sustained during adult life by quiescent primitive progenitors that divide intermittently. Some, but not all, aspects of the fetal differentiation program are reacquired after chemotherapy.

Abstract
This study was designed to investigate one component of the Wnt/beta-catenin signaling pathway that has been implicated in stem cell self-renewal. Retroviral-mediated introduction of stable beta-catenin to primitive murine bone marrow cells allowed the expansion of multipotential c-Kit(low)Sca-1(low/-)CD19(-) CD11b/Mac-1(-)Flk-2(-)CD43(+)AA4.1(+)NK1.1(-)CD3(-)CD11c(-)Gr-1(-)CD45R/B220(+) cells in the presence of stromal cells and cytokines. They generated myeloid, T, and B lineage lymphoid cells in culture, but had no T lymphopoietic potential when transplanted. Stem cell factor and IL-6 were found to be minimal requirements for long-term, stromal-free propagation, and a beta-catenin-transduced cell line was maintained for 5 mo with these defined conditions. Although multipotential and responsive to many normal stimuli in culture, it was unable to engraft several types of irradiated recipients. These findings support previous studies that have implicated the canonical Wnt pathway signaling in regulation of multipotent progenitors. In addition, we demonstrate how it may be experimentally manipulated to generate valuable cell lines.

Abstract
OBJECTIVE Induction of hematopoietic cells from human embryonic stem (ES) cells has been reported recently. However, before cells derived from human ES cells can be used in the clinic, preclinical studies using these cells in experimental primates will be necessary. Therefore, we attempted to establish a method to induce hematopoietic cells robustly and abundantly from primate ES cells. METHODS A primate ES cell line, CMK-6, derived from the cynomolgus monkey was used in this study. We adapted a method to induce hematopoiesis from CMK-6 cells on feeder cells, and tested the effectiveness of three kinds of feeder cell lines (OP9, C2C12, and C3H10T1/2). In addition, we tested the effect of vascular endothelial growth factor (VEGF) and insulin-like growth factor-II (IGF-II) on hematopoiesis induction from CMK-6 cells. RESULTS VEGF and IGF-II showed an extremely strong synergistic effect to induce hematopoiesis from CMK-6 cells. C3H10T1/2 cells proved to be very useful for the induction of hematopoiesis from CMK-6 cells, and the production of blood cells on C3H10T1/2 cells has been maintained as long as 5 months. During this long period, ES cell derivatives continuously produced mature blood cells, including terminally differentiated cells. CONCLUSION We have developed an original method to produce enriched blood cells abundantly from primate ES cells for an extremely long period. This method may represent a good in vitro model for studying primate hematopoiesis and related diseases. Furthermore, our method may be useful for preclinical studies of transfusion therapy using blood cells derived from ES cells in experimental primate systems.

Abstract
Cancers arise from stem cells in adult tissues and the cells that make up a cancer reflect the same stem cell --> progeny --> differentiation progression observed in normal tissues. All adult tissues are made up of lineages of cells consisting of tissue stem cells and their progeny (transit-amplifying cells and terminally differentiated cells); the number of new cells produced in normal tissue lineages roughly equals the number of old cells that die. Cancers result from maturation arrest of this process, resulting in continued proliferation of cells and a failure to differentiate and die. The biological behavior, morphological appearance, and clinical course of a cancer depend on the stage of maturation at which the genetic lesion is activated. This review makes a comparison of cancer cells to embryonic stem cells and to adult tis sue stem cells while addressing two basic questions: (1) Where do cancers come from?, and (2) How do cancers grow? The answers to these questions are critical to the development of approaches to the detection, prevention, and treatment of cancer.

Abstract
Cytokeratins are the largest subfamily of intermediate filament proteins and include more than 20 different gene products, which are expressed in an epithelial tissue-specific manner. We studied by immunohistochemistry and confocal microscopy the distribution of cytokeratin subtypes in the biliary system of adult rat liver. A cytokeratin (CK)19+/7- cholangiocyte population was observed in the smaller branches of the biliary tree including the canals of Hering. They proliferated after 2-acetaminofluorene (AAF) administration, although later the typical oval cells expressed CK7. This observation suggests that cholangiocytes with this cytokeratin phenotype may harbor adult hepatic stem cells. The CK19+/7- cholangiocytes were not present in the rat liver at birth, but developed postnatally. Similar cell populations were not observed in human livers. In conclusion, we propose that the CK19+/7- phenotype may be characteristic for adult hepatic stem cells in rat liver and that these cells are generated de novo after birth.

Abstract
The zinc finger transcription factor GATA-1 is essential for both primitive (embryonic) and definitive (adult) erythropoiesis. To define the roles of GATA-1 in the production and differentiation of primitive and definitive erythrocytes, we established GATA-1-null embryonic stem cell lines in which GATA-1 was able to be conditionally expressed by using the tetracycline conditional gene expression system. The cells were subjected to hematopoietic differentiation by coculturing on OP9 stroma cells. We expressed GATA-1 in the course of primitive and definitive erythropoiesis and analyzed the ability of GATA-1 to rescue the defective erythropoiesis caused by the GATA-1 null mutation. Our results show that GATA-1 functions in the proliferation and maturation of erythrocytes in a distinctive manner. The early-stage expression of GATA-1 during both primitive and definitive erythropoiesis was sufficient to promote the proliferation of red blood cells. In contrast, the late-stage expression of GATA-1 was indispensable to the terminal differentiation of primitive and definitive erythrocytes. Thus, GATA-1 affects the proliferation and differentiation of erythrocytes by different mechanisms.

Abstract
Hematopoiesis can be scripted into multiple acts that open with hematopoietic stem cells (HSCs) and close with the production of nonproliferating mature blood cells. Its lifelong durability requires that HSCs choose between mutually exclusive fates: self-renewal versus a capacity for multilineage differentiation. The growth factor independence 1 (Gfi-1) oncoprotein was first discovered playing supporting roles in lymphopoiesis and myelopoiesis. Two new studies indicate that Gfi-1 regulates self-renewal and preserves the functional integrity of HSCs, adding Gfi-1 to the short list of intrinsic regulators of self-renewal and casting it among the major players featured in starring roles in hematopoiesis.

Abstract
Our forefathers in pathology, on observing cancer tissue under the microscope in the mid-19th century, noticed the similarity between embryonic tissue and cancer, and suggested that tumors arise from embryo-like cells [Recherches dur le Traitement du Cancer, etc. Paris. (1829); Editoral Archiv fuer pathologische Anatomie und Physiologie und fuer klinische Medizin 8 (1855) 23]. The concept that adult tissues contain embryonic remnants that generally lie dormant, but that could be activated to become cancer was later formalized by Cohnheim [Path. Anat. Physiol. Klin. Med. 40 (1867) 1-79; Virchows Arch. 65 (1875) 64] and Durante [Arch. Memori ed Osservazioni di Chirugia Practica 11 (1874) 217-226], as the "embryonal rest" theory of cancer. An updated version of the embryonal rest theory of cancer is that cancers arise from tissue stem cells in adults. Analysis of the cellular origin of carcinomas of different organs indicates that there is, in each instance, a determined stem cell required for normal tissue renewal that is the most likely cell of origin of carcinomas [Lab. Investig. 70 (1994) 6-22]. In the present review, the nature of normal stem cells (embryonal, germinal and somatic) is presented and their relationships to cancer are further expanded. Cell signaling pathways shared by embryonic cells and cancer cells suggest a possible link between embryonic cells and cancer cells. Wilm's tumors (nephroblastomas) and neuroblastomas are presented as possible tumors of embryonic rests in children. Teratocarcinoma is used as the classic example of the totipotent cancer stem cell which can be influenced by its environment to differentiate into a mature adult cell. The observation that "promotion" of an epidermal cancer may be accomplished months or even years after the initial exposure to carcinogen ("initiation"), implies that the original carcinogenic event occurs in a long-lived epithelial stem cell population. The cellular events during hepatocarcinogenesis illustrate that cancers may arise from cells at various stages of differentiation in the hepatocyte lineage. Examples of genetic mutations in epithelial and hematopoietic cancers show how specific alterations in gene expression may be manifested as maturation arrest of a cell lineage at a specific stage of differentiation. Understanding the signals that control normal development may eventually lead us to insights in treating cancer by inducing its differentiation (differentiation therapy). Retinoid acid (RA) induced differentiation therapy has acquired a therapeutic niche in treatment of acute promyelocytic leukemia and the ability of RA to prevent cancer is currently under examination.

Abstract
The molecular interactions between transcription factors and cofactors play crucial roles in various biological processes, including haematopoiesis. FOG-1 is a cognate cofactor of GATA-1, and the FOG-1/GATA-1 complex is essential for the haematopoietic differentiation of erythroid cells and megakaryocytes. In order to elucidate the biological functions of FOG-1 in the different contexts of cell differentiation, we analysed the effects of FOG-1 expression on haematopoietic cell differentiation, using a combination of in vitro differentiation of mouse embryonic stem (ES) cells and conditional gene expression. FOG-1 suppressed the proliferation of primitive and definitive erythroid cells in all stages of differentiation. However, FOG-1 inhibited and enhanced megakaryopoiesis in the early and late differentiation stages, respectively, through different molecular mechanisms. In addition, FOG-1 inhibited the proliferation of ES cells, the molecular mechanism of which differs from those of erythroid and megakaryocytic cells. These results suggest that FOG-1 functions in a cell differentiation context-dependent manner.

Abstract
Long before their existence was proven, work with blood islands pointed to the existence of hemangioblasts in the embryo, and it was widely accepted that such cells existed. In contrast, though evidence for adult hemangioblasts appeared at least as early as 1932, until quite recently, it was commonly assumed that there were no adult hemangioblasts. Over the past decade, these views have changed, and it is now generally accepted that a subset of bone marrow cells or their progeny can and do function as adult hemangioblasts. This chapter will examine the basic biology of bone marrow-derived hemangioblasts and endothelial cell progenitors (angioblasts) and the relationship of these adult cells to their embryonic counterparts. Efforts to define the endothelial cell progenitor phenotype will also be discussed, though to date, there is no consensus on the definitive adult phenotype, probably because there are multiple phenotypes and because the cells are plastic. Also examined are the putative roles of bone marrow-derived cells in vascular homeostasis and repair, including both their ability to differentiate and contribute directly to vascular repair, as well as to promote vascular growth by secreting pro-angiogenic factors. Finally, the use of bone marrow cells as therapeutic tools will be addressed.
