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...

BACKGROUND: Mutations in tetratricopeptide repeat domain 7A (TTC7A) and its mouse orthologue Ttc7 result in a multisystemic disease, mostly affecting epithelial barriers and the immune system. Despite successful hematopoietic stem cell transplantation, ongoing progression of gastrointestinal manifestations can be life-threatening in TTC7A-deficient patients. OBJECTIVE: To identify whether TTC7A mutations dysregulate epithelial cells only, or whether a cell-intrinsic defect in lymphocytes or other cells contributes to disease manifestations...

The role of CD133 (Prominin-1) as a cancer stem cell marker may be useful for therapeutic approaches and prognostication in prostate cancer patients. We investigated the stem-cell-related function and biological features of a subpopulation of CD133+ cells isolated from established primary human prostate cancer cell lines. The CD133+ cells sorted from human prostate cancer 22Rv1 exhibited high clonogenic and tumorigenic capabilities, sphere forming capacity and serially reinitiated transplantable tumors in NOD-SCID mice...

Stem cell therapy is a promising approach for the treatment of type 1 diabetes mellitus (T1D). Previous studies recommended regular exercise for the control of T1D. Experimental studies showed that a combination of stem cells and exercise yielded a better outcome. Yet, the effect of exercise programs following stem cell transplantation in patients with T1D has not been investigated. Thus, the current study aimed to examine the effect of a combined exercise program on measures of glycemic control in patients with T1D who received autologous bone marrow stem cell transplantation (ABMSCT)...

Background: The current standard of care for classical Hodgkin lymphoma (HL) is multiagent chemotherapy with or without radiation. In patients who relapse or fail to respond, additional high-dose chemotherapy with autologous hematopoietic stem cell transplantation (AHSCT) can improve progression-free survival (PFS). Novel therapies are required for patients refractory to chemotherapy and AHSCT. The mammalian target of rapamycin inhibitor everolimus has shown preliminary activity in preclinical models of HL and promising efficacy in patients with relapsed or refractory HL...

Rationale: Pluripotent stem cells (PSCs) are being investigated as a cell source for regenerative medicine since they provide an infinitive pool of cells that are able to differentiate towards every cell type of the body. One possible therapeutic application involves the use of these cells to treat myocardial infarction (MI), a condition where billions of cardiomyocytes (CMs) are lost. Although several protocols have been developed to differentiate PSCs towards CMs, none of these provide a completely pure population, thereby still posing a risk for neoplastic teratoma formation...

Rationale: Non-invasive tracking of transplanted cells is critical in evaluating delivery, migration and prognosis of cell therapies. Methods: We formulated a nano-contrast agent consisting of a perfluorooctylbromide (PFOB) core within a shell of poly (lactic-co-glycolic acid) (PLGA) followed by a coat of polystyrene sulfonate (PSS) for 19 F MRI. The nano-contrast agent (PSS-NP) was characterised by DLS and the uptake efficiency of the nano-contrast agent (PSS-NP) was tested using flow cytometry, in vitro MRI and confocal microscopy...

Survival in children with relapsed/refractory acute myeloid leukemia is unsatisfactory. Treatment consists of one course fludarabine, cytarabine and liposomal daunorubicin, followed by fludarabine and cytarabine and stem-cell transplantation. Study ITCC 020/I-BFM 2009-02 aimed to identify the recommended phase 2 dose of clofarabine replacing fludarabine in the abovementioned combination regimen (3+3 design). Escalating dose-levels of clofarabine (20-40mg/m2/day x5days) and liposomal daunorubicin (40-0mg/m2/day) were administered with cytarabine (2g/m2/day x5days)...

Diseases with clonal hematopoiesis such as myelodysplastic syndrome and acute myeloid leukemia have high rates of relapse. Only a small subset of acute myeloid leukemia patients are cured with chemotherapy alone. Relapse in these diseases occurs at least in part due to the failure to eradicate leukemic stem cells or hematopoietic stem cells in myelodysplastic syndrome. CD123, the alpha chain of the interleukin-3 receptor heterodimer, is expressed on the majority of leukemic stem cells and myelodysplastic syndrome hematopoietic stem cells and in 80% of acute myeloid leukemia...

Severe aplastic anemia results from profound hematopoietic stem cell loss. T cells and interferon gamma have long been associated with severe aplastic anemia, yet the underlying mechanisms driving hematopoietic stem cell loss remain unknown. Using a mouse model of severe aplastic anemia, we demonstrate that interferon gamma-dependent hematopoietic stem cell loss required macrophages. Interferon gamma was necessary for bone marrow macrophage persistence, despite loss of other myeloid cells and hematopoietic stem cells...

In France, endothelial dysfunction represents approximately one half of the indications for corneal transplants performed each year. However, the use of endothelial keratoplasty is limited by the technical difficulty of the procedure, a shortage of available grafts, and the potential for graft failure or rejection. These limitations are driving researchers to develop new, less invasive, and more effective therapies. Corneal endothelial cell therapy is being explored as a potential therapeutic measure, to avoid the uncertainty associated with grafting...

Cases of extracorporeal membrane oxygenation (ECMO) bridged lung transplantation (LTx) are rare in Japan because an allocation system to prioritize patients based on urgency remains to be established. For critically ill patients who cannot wait for a brain-dead donor LTx, ECMO bridge to living-donor LTx may be the only practical option. A 21-year-old woman with pleuroparenchymal fibroelastosis after hematopoietic stem cell transplantation was admitted to our hospital with rapidly progressive respiratory failure...

Alpha-mannosidosis (α-mannosidosis) is a rare lysosomal storage disorder with an autosomal recessive inheritance caused by mutations in the gene encoding for the lysosomal α-d-mannosidase. So far, 155 variants from 191 patients have been identified and in part characterized at the biochemical level. Similarly to other lysosomal storage diseases, there is no relationship between genotype and phenotype in alpha-mannosidosis. Enzyme replacement therapy is at the moment the most effective therapy for lysosomal storage disease, including alpha-mannosidosis...

G-protein-coupled receptors (GPCRs) are the largest family of receptors in humans. GPCRs are seven-transmembrane receptors that are activated by the binding of a ligand to the extracellular domain. In addition to the endogenous ligands, auto-antibodies (aab) can also bind to the GPCRs. They can activate different and specific cellular pathways which contribute to various diseases. In this review, the authors summarize the knowledge about antibodies targeting GPCRs and their effects and relevance in the pathogenesis of various diseases and their use in clinical diagnostics...

Salvage haploidentical HSCT is considered in patients with severe aplastic anemia (SAA) if matched unrelated donor (MUD) is unavailable. However, studies on haplo- and MUD transplantation in SAA are yet lacking. The present study retrospectively analyzed the outcomes of 89 young SAA patients who underwent unmanipulated alternative hematopoietic stem cell transplantation (HSCT) between September 2012 and September 2016 at our single center. 41 patients received haploidentical donors, and 48 patients received MUD for HSCT...
