Bone is a complex endocrine organ that facilitates structural support, protection to vital organs, sites for hematopoiesis, and calcium homeostasis. The bone marrow microenvironment is a heterogeneous niche consisting of multipotent musculoskeletal and hematopoietic progenitors and their derivative terminal cell types. Amongst these progenitors, bone marrow mesenchymal stem/stromal cells (BMSCs) may differentiate into osteogenic, adipogenic, myogenic, and chondrogenic lineages to support musculoskeletal development as well as tissue homeostasis, regeneration and repair during adulthood...

NOTCH1 is a prevalent signaling pathway in T cell acute lymphoblastic leukemia (T-ALL), but crucial NOTCH1 downstream signals and target genes contributing to T-ALL pathogenesis cannot be retrospectively analyzed in patients and thus remain ill defined. This information is clinically relevant, as initiating lesions that lead to cell transformation and leukemia-initiating cell (LIC) activity are promising therapeutic targets against the major hurdle of T-ALL relapse. Here, we describe the generation in vivo of a human T cell leukemia that recapitulates T-ALL in patients, which arises de novo in immunodeficient mice reconstituted with human hematopoietic progenitors ectopically expressing active NOTCH1...

Understanding the molecular pathways controlling hematopoietic stem cell specification and expansion is a necessary milestone to perform regenerative medicine. Here, we used the zebrafish model to study the role of the ckit signaling pathway in this process. We show the importance of kitb/kitlgb signaling in the specification and expansion of hematopoietic stem cells (HSCs), in the hemogenic endothelium and caudal hematopoietic tissue (CHT), respectively. Moreover, we identified the zebrafish ortholog of Oncostatin M (osm) in the zebrafish genome...

Hematopoietic stem cells (HSCs) require a supportive microenvironment to regulate their function and produce sufficient hematopoietic cells over the lifetime of an individual. With the exception of fish, all vertebrates, including mammals, maintain HSCs in a complex niche within the bone marrow. Several bone specific cellular populations have been implicated as components of the HSC niche and are part of a complex network that regulates HSC functions. However, the full extent of interactions within the HSC niche, and the role of individual cell populations remain to be fully elucidated...

Mesenchymal stromal cells (MSC) support hematopoietic stem cells (HSC) in vivo and enhance HSC engraftment and hematopoietic recovery upon co-transplantation with HSC. These data have led to the hypothesis that MSC may impact the HSC niche, leading to changes in HSC retention and trafficking. We studied the effect of MSC administration on the HSC compartment in the bone marrow (BM) in mice. Following injection of MSC, HSC numbers in the BM were decreased coinciding with an increased cell cycle activity compared to PBS-injected controls...

Within bone, mesenchymal stromal cells (MSCs) exist within the bone marrow stroma (BM-MSC) and the endosteal niche, as cells lining compact bone (CB-MSCs). This study isolated and characterised heterogeneous MSC populations from each niche and subsequently investigated the effects of extensive cell expansion, analysing population doublings (PDs)/cellular senescence, colony-forming efficiencies (CFEs), MSC cell marker expression, and osteogenic/adipogenic differentiation. CB-MSCs and BM-MSCs demonstrated similar morphologies and PDs, reaching 100 PDs...

Bone marrow mesenchymal stem cells (BMSCs), the important component and regulator of bone marrow microenvironment, give rise to hematopoietic-supporting stromal cells and form hematopoietic niches for hematopoietic stem cells (HSCs). However, how BMSC differentiation affects hematopoiesis is poorly understood. In this review, we focus on the role of BMSC differentiation in hematopoiesis. We discussed the role of BMSCs and their progeny in hematopoiesis. We also examine the mechanisms that cause differentiation bias of BMSCs in stress conditions including aging, irradiation, and chemotherapy...

Extramedullary hematopoiesis (EMH) is observed in the fetal liver and the spleen under physiological conditions, but can rarely occur as pathologic condition after birth. EMH is observed in various anatomical sites in patients with hypoxia-inducing conditions, such as idiopathic myelofibrosis. The nature of the microenvironment for the maintenance of hematopoietic stem cells (HSCs) in EMH is unclear. Recent studies showed that mesenchymal stem/stromal cell (MSC)-derived cells, that can differentiate into various types of cells, play critical roles in the formation of hematopoietic niches...

Macrophages are present in most of the tissues in the organism. They are basically separated into two categories: the resident macrophages, specific of the tissue and capable of proliferation, and the macrophages deriving from the monocyte differentiation. In the bone marrow, the "resident" macrophages are part of the hematopoietic stem cell niche.Those macrophages are known to have a role in the support of erythropoiesis (Chow, Nat Med 19:429-436, 2013), the maintenance of stem cell in their niches (Chow, J Exp Med 208:261-271, 2011), and are an independent self-renewing population (Hashimoto, Immunity 38:792-804, 2013)...

Multipotent mesenchymal stromal cells (MSCs) participate in the formation of bone marrow niches for hematopoietic stem cells. Donor MSCs can serve as a source of recovery for niches in patients with graft failure (GF) after allogeneic bone marrow (BM) transplantation. Since only few MSCs reach the BM after intravenous injection, MSCs were implanted into the iliac spine. For 8 patients with GF after allo-BMT, another hematopoietic stem cell transplantation with simultaneous implantation of MSCs from their respective donors into cancellous bone was performed...

Mesenchymal stromal cells (MSCs) are multipotent progenitors supporting bone marrow hematopoiesis. MSCs have an efficient DNA damage response (DDR) and are consequently relatively radio-resistant cells. Therefore, MSCs are key to hematopoietic reconstitution following total body irradiation (TBI) and bone marrow transplantation (BMT). The bone marrow niche is hypoxic and via the heterodimeric transcription factor Hypoxia-inducible factor-1 (Hif-1), hypoxia enhances the DDR. Using gene knock-down, we have previously shown that the Hif-1α subunit of Hif-1 is involved in mouse MSC radio-resistance, however its exact mechanism of action remains unknown...

There are limited methods available to study skeletal stem, progenitor, and progeny cell activity in normal and diseased contexts. Most protocols for skeletal stem cell isolation are based on the extent to which cells adhere to plastic or whether they express a limited repertoire of surface markers. Here, we describe a flow cytometry-based approach that does not require in vitro selection and that uses eight surface markers to distinguish and isolate mouse skeletal stem cells (mSSCs); bone, cartilage, and stromal progenitors (mBCSPs); and five downstream differentiated subtypes, including chondroprogenitors, two types of osteoprogenitors, and two types of hematopoiesis-supportive stroma...

Hematopoietic stem cells (HSCs) that give rise to all kinds of hematopoietic lineage cells on various demands throughout life are maintained in a specialized microenvironment called "niche" in the bone marrow (BM). Defining niche cells and unveiling its function have been the subject of intense study, and it is becoming increasingly clear how niche cells regulate HSCs in normal hematopoiesis. Leukemia stem cells (LSCs), which are able to produce leukemic cells and maintain leukemic clones, are assumed to share common features with healthy HSCs...

Aging of hematopoietic stem cells (HSCs) is associated with a decline in their regenerative capacity and multilineage differentiation potential, contributing to the development of blood disorders. The bone marrow microenvironment has recently been suggested to influence HSC aging, but the underlying mechanisms remain largely unknown. Here we show that HSC aging critically depends on bone marrow innervation by the sympathetic nervous system (SNS), as loss of SNS nerves or adrenoreceptor β3 signaling in the bone marrow microenvironment of young mice led to premature HSC aging, as evidenced by appearance of HSC phenotypes reminiscent of physiological aging...

Stem cells are characterized by their unique ability to both self-renew and differentiate along multiple cellular lineages. Self-renewal and differentiation must be tightly controlled to ensure an appropriate stem cell pool in tissue over the lifetime of an organism. Elucidating the mechanisms controlling stem cell fate and maintenance remains a key challenge in stem cell biology. Hematopoietic stem cells (HSCs) are responsible for the lifelong production of multiple blood cell lineages. To remain functional, these cells must interact with a particular microenvironment, known as the stem cell niche...

Hematopoietic stem cells (HSCs) are exposed to various insults, such as genotoxic stress, inflammation, and infection, which directly affect HSCs. These insults deplete HSCs, cause a functional decline in HSCs, and promote their aging and transformation. However, the impact of hematopoietic insults on niche cells remains largely unknown. We have previously reported that p53 is activated in blood vessels by various stresses, including hypoxia, inflammation, and aging, and contributes to tissue dysfunction and metabolic abnormalities...

BACKGROUND: Myelodysplastic Syndromes (MDS) and Acute Myeloid Leukemia (AML) are hematological stem cell diseases mainly of the elderly. Studies indicate a close relationship between bone metabolism and hematopoietic stem cells within the osteo-hematopoietic niche. However, it remains unclear how the disturbed interaction within the osteo-hematopoietic niche affects bone homeostasis in MDS and AML patients. METHODS: We utilized data of a large German statutory health insurance of approximately 2 million persons living in the German federal state of Saxony...

Bone marrow contains numerous different cell types arising from hematopoietic stem cells (HSCs) and non-hematopoietic mesenchymal/skeletal stem cells, in addition to other cell types such as endothelial cells- these non-hematopoietic cells are commonly referred to as stromal cells or microenvironment cells. HSC function is intimately linked to complex signals integrated by their niches, formed by combinations of hematopoietic and stromal cells. Studies of hematopoietic cells have been significantly advanced by flow cytometry methods, enabling the quantitation of each cell type in normal and perturbed situations, in addition to the isolation of these cells for molecular and functional studies...

The stem cell compartment of the hematopoietic system constitutes one of the most radiosensitive tissues of the body and leukemias represent one of the most frequent radiogenic cancers with short latency periods. As such, leukemias may pose a particular threat to astronauts during prolonged space missions. Control of hematopoiesis is tightly governed by a specialized bone marrow (BM) microenvironment/niche. As such, any environmental insult that damages cells of this niche would be expected to produce pronounced effects on the types and functionality of hematopoietic/immune cells generated...
