The development of human innate lymphoid cells (ILCs) remains poorly characterized. In a recent issue of Cell, Lim et al. show that human peripheral-blood CD117(+) ILCs harbor ILC precursors (ILCPs) derived from hematopoietic stem cells. Peripheral-blood ILCPs can generate all ILC subsets in vivo and in vitro.

BACKGROUND: Allogeneic hematopoietic cell transplantation (HCT) is a curative therapy for patients with acute myeloid leukemia (AML). However, post-HCT relapse and regimen-related toxicity remain significant barriers to long-term survival. In recent years, new conditioning regimens have been explored to improve transplantation outcomes in patients with AML. Treosulfan combines a potent immunosuppressive and antileukemic effect with a low toxicity profile. METHODS: To investigate the role of treosulfan-based conditioning, the European Society for Blood and Marrow Transplantation Acute Leukemia Working Party performed a registry analysis of 520 adult patients with AML who received treosulfan-based conditioning and underwent HCT between 2000 and 2012, including 225 patients in first complete remission, 107 in second or later complete remission, and 188 with active/advanced disease 188 (88 with primary refractory disease)...

CD34(+)-selected stem cell boost (SCB) without conditioning have recently been utilized for poor graft function (PGF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) with promising results. Unfortunately, many patients have been unable to receive the boost infusion as their donors were unwilling or unable to undergo an additional stem cell collection. Therefore, we conducted this study utilizing either fresh or cryopreserved peripheral blood stem cell products to create CD34(+)-selected boost infusions for the treatment of PGF...

BACKGROUND: While it is known that irradiation can induce local and systemic bone loss over time, how focal irradiation induces systemic bone complications remains unclear. Immune cells are thought to be crucial to bone homeostasis, and abnormal immune cells lead to serious disruption of bone homeostasis, such as in acute lymphoblastic leukaemia. This disruption primarily occurs due to inhibition of the osteogenic differentiation of bone mesenchymal stem cells (BMSCs). METHODS: In this study, we detected local and systemic bone loss in trabecular bone by micro-computed tomography (micro-CT) and measurement of peroxisome proliferator-activated receptor gamma (PPARγ) and runt-related transcription factor 2 (RUNX2) expression in BMSCs using real-time polymerase chain reaction and western blotting...

Posterior reversible encephalopathy syndrome (PRES) is diagnosed based on neuroradiological findings. Typically, PRES is reversible and presents with a good outcome; however, fatal outcomes have been reported. We report an autopsied case showing PRES-like neuroradiological findings associated with premedication including tacrolimus for autologous peripheral blood stem cell transplantation in a 28-year-old woman with a 2-year history of acute myeloid sarcoma/acute myeloid leukemia. Neurological examination revealed disturbed consciousness, muscle weakness in all extremities, and bilaterally diminished tendon reflexes...

Immunophenotypical characterization of mesenchymal stem cells is fundamental for the design and execution of sound experimental and clinical studies. The scarce availability of species-specific antibodies for canine antigens has hampered the immunophenotypical characterization of canine mesenchymal stem cells (MSC). The aim of this study was to select a panel of species-specific direct antibodies readily useful for canine mesenchymal stem cells characterization. They were isolated from perivisceral and subcutaneous adipose tissue samples collected during regular surgeries from 8 dogs...

Optimal timing of apheresis initiation is important for maximizing the hematopoietic stem cell (HSC) yield. This study aimed to identify useful parameters from automatic hematology analyzers for predicting the peripheral blood CD34+ cell count after mobilization. We prospectively enrolled 53 healthy donors and 72 patients, and evaluated 43 cell morphology parameters from Unicel DxH800 (Beckman Coulter, USA) and Advia 2120i (Siemens Healthcare Diagnostics, USA). The correlation of each parameter with the CD34+ cell count in pre-apheresis blood samples was analyzed...

Patients with chronic obstructive pulmonary disease (COPD) have chronic, irreversible airway inflammation; currently, there is no effective or curative treatment and the main goals of COPD management are to mitigate symptoms and improve patients' quality of life. Stem cell based therapy offers a promising therapeutic approach that has shown potential in diverse degenerative lung diseases. Preclinical studies have demonstrated encouraging outcomes of mesenchymal stem/stromal cells (MSCs) therapy for lung disorders including emphysema, bronchopulmonary dysplasia, fibrosis, and acute respiratory distress syndrome...

Various clinical studies have revealed that cardiovascular diseases (CVD) are associated with bone loss diseases such as osteoporosis and periodontitis, especially in older population. As one of the best-established risk factors of CVD, hyperlipidemia is also reported to interfere with the metabolism, function and regeneration of mineralized tissues. Derived from postnatal tissue reservoirs, mesenchymal stem cells (MSCs) are considered promising cell sources for mesenchymal and non-mesenchymal tissue regeneration based on their capacities for self-renewal and multi-lineage differentiation as well as potent immunosuppressive effects, secretion of cytokines and regulation of vascularization...

Multiple nonleukemic myeloid sarcoma (MS) is a rare form of MS that is developed in multiple anatomic sites other than bone marrow at diagnosis, without a preceding myeloid neoplasm. The prevalence, prognosis, and optimal management of multiple nonleukemic MS have not been addressed. The role of allogenic or autologous hematopoietic cell transplantation (HCT) for nonleukemic MS is also less well defined. We present a case of MS characterized by systemic lymphadenopathies and multiple effusions, which presumably had a very poor prognosis...

Bone marrow-derived progenitor cells are mobilized into the peripheral blood after acute myocardial injury and in chronic ischemic heart disease. However, the mechanisms responsible for this mobilization are poorly understood. We examined the relationship between plasma levels of bioactive lipids and number of circulating progenitor cells (CPCs) in patients (N = 437) undergoing elective or emergent cardiac catheterization. Plasma levels of sphingosine-1 phosphate (S1P) and ceramide-1 phosphate (C1P) were quantified using mass spectrometry...

We sought to evaluate the physiological background and the effects of CD34(+) cell transplantation on diastolic parameters in nonischemic dilated cardiomyopathy patients (DCM). We enrolled 38 DCM patients with NYHA class III and LVEF <40% who underwent transendocardial CD34(+) cell transplantation. Peripheral blood CD34(+) cells were mobilized by G-CSF, collected via apheresis, and injected transendocardially in the areas of myocardial hibernation. Patients were followed for 1 year. At baseline, estimated filling pressures were significantly elevated (E/e'≥15) in 18 patients (Group A), and moderately elevated (E/e'<15) in 20 patients (Group B)...

Lipopolysaccharide (LPS) is a pertinent deleterious factor in oral microenvironment for cells which are carriers of regenerative processes. The aim of this study was to investigate the emerging in vitro effects of LPS (E.coli) on human periodontal ligament stem cell (PDLSC) functions and associated signaling pathways. We demonstrated that LPS did not affect immunophenotype, proliferation, viability and cell cycle of PDLSCs. However, LPS modified lineage commitment of PDLSCs inhibiting osteogenesis by downregulating Runx2, ALP and Ocn mRNA expression, while stimulating chondrogenesis and adipogenesis by upregulating Sox9 and PPARγ mRNA expression...

A single subcutaneous (SC) injection of plerixafor results in rapid mobilization of hematopoietic progenitors but fails to mobilize 33% of normal allogeneic sibling donors in one apheresis. We hypothesized that changing the route of administration of plerixafor from SC to intravenous (IV) may overcome the low stem cell yields and allow collection in one day. A phase I trial followed by a phase II efficacy trial was conducted in allogeneic sibling donors. The optimal dose of IV plerixafor was determined to be 0...

Peripheral blood stem cell transplantation (PBSCT) is an effective treatment for hematological malignancies. Mobilization of peripheral blood progenitor cells performs in different ways among transplantation centers. Forceful mobilization schedules are comprised of growth factor alone, chemotherapy along with growth factor and also, a newly combination of novel agent such as plerixafor with any approach. With the appearance of numerous modifications in stem cell mobilization field over the past decade and advent of novel stem cell mobilization techniques, it seems to be necessary to review recent publications about stem cell mobilization strategies to respond above cited issues...

Very small embryonic-like stem cells (VSELs) are major pluripotent stem cells involved in vascular and tissue regeneration and constitute a recruitable pool of stem/progenitor cells with putative instrumental role in organ repair. Here, we hypothesized that VSELs might be mobilized from the bone marrow (BM) to peripheral blood (PB) in patients with hypoxic lung disease or pulmonary hypertension (PH). The objective of the present study was then to investigate the changes in VSELs number in peripheral blood of patients with hypoxic lung disease and PH...

OBJECTIVE: Little is known regarding acute local and systemic processes following anterior cruciate ligament (ACL) rupture. No study has elucidated whether bone marrow-derived mesenchymal stem cells (MSCs) are mobilized into circulation and recruited to the injured joint. METHODS: In part one, Lewis rats were randomized to noninvasive ACL rupture (Rupture) or non-injured (Control) (n=6/group). After 72 hours, whole blood MSC concentration was assessed using flow cytometry...
