BACKGROUND: There is considerable heterogeneity in processing of stem cells for hematopoietic stem cell transplantation across Europe. The Foundation for the Accreditation of Cellular Therapy (FACT)-Joint Accreditation Committee International Society for Cellular Therapy and European Society for Blood and Marrow Transplantation (EBMT) (JACIE) standards provide minimum guidelines that, however, leave room for significant variations in practices at the individual transplantation center (TC)...

Chemotherapy and hematopoietic stem cell transplantation are effective treatments for most Hodgkin lymphoma patients, however there remains a need for better tumor-specific target therapy in Hodgkin lymphoma patients with refractory or relapsed disease. We demonstrate that membrane CD83 is a diagnostic and therapeutic target, highly expressed in Hodgkin lymphoma cell lines and Hodgkin and Reed-Sternberg cells in 29/35 (82.9%) Hodgkin lymphoma patient lymph node biopsies. CD83 from Hodgkin lymphoma tumor cells was able to trogocytose to surrounding T cells and interestingly, the trogocytosing CD83+T cells expressed significantly more PD-1 compared to CD83- T cells...

We conducted a phase 2 study in which patients undergoing allogeneic hematopoietic stem cell transplantation received Tocilizumab in addition to standard immune suppression with tacrolimus and methotrexate for graft versus host disease prophylaxis. Thirty-five patients were enrolled between January 2015 and June 2016. The median age of the cohort was 66 (range 22-76). All patients received busulfan-based conditioning, and were transplanted with HLA-matched related or matched unrelated bone marrow or peripheral stem cell grafts...

BACKGROUND: Mesenchymal stem cells (MSC) are used for several therapeutic applications to improve the functions of bone, cardiac, nervous tissue as well as to facilitate the repopulation of hematopoietic stem cells. MSC give rise to the non-hematopoietic stromal cells of the bone marrow and are important for the maintenance of normal hematopoiesis. Chemotherapeutic drugs used for treatment of leukemia extensively damage the stromal cells and alter their gene expression profiles. METHODS: We determined the changes in adipogenic, osteogenic differentiation, phenotypic and gene expression in MSC during treatment with chemotherapeutic drugs cytarabine, daunorubicin and vincristine...

BACKGROUND: Sinusoidal obstruction syndrome (SOS), also called hepatic veno-occlusive disease (VOD), is a potentially life-threatening complication of hematopoietic stem cell transplantation (HSCT) that affects about 1 in 7 patients undergoing this procedure. SOS/VOD is caused by the conditioning regimens administered prior to HSCT; in some cases, SOS/VOD results from chemotherapy alone. SOS/VOD usually develops within three weeks following HSCT; however, it can have later onset.

CXCR4 is a 7-transmembrane receptor expressed by hematopoietic stem cells and progeny, as well as by ≥ 48 different cancers types. CXCL12, the only chemokine ligand of CXCR4, is secreted within the tumor microenvironment, providing sanctuary for CXCR4+ tumor cells from immune surveillance and chemotherapeutic elimination by 1) stimulating pro-survival signaling and 2) recruiting CXCR4+ immunosuppressive leukocytes. Additionally, distant CXCL12-rich niches attract and support CXCR4+ metastatic growths. Accordingly, CXCR4 antagonists can potentially obstruct CXCR4-mediated pro-survival signaling, recondition the CXCR4+ leukocyte infiltrate from immunosuppressive to immunoreactive, and inhibit CXCR4+ cancer cell metastasis...

Parents/caregivers of hospitalized patients are at risk of sleep disruption. We performed a cross-sectional quantitative and qualitative evaluation of sleep in parents/caregivers of children undergoing hematopoietic stem cell transplant (HSCT; n = 17). Additionally, we explored the frequency of room entries for hospitalized patients undergoing HSCT (n = 189 nights). Twelve caregivers (71%) demonstrated significant sleep disturbance, 12 (71%) described sleep quality as poor, 15 (88%) averaged < 6 hours of sleep per night, 14 (82%) awakened at least four times per night...

BACKGROUND: Autologous peripheral blood hematopoietic stem cell (PBSC) collection efficiency (CE) is reportedly affected by the patient's blood properties; however, studies to identify factors correlated with CE have shown inconsistent results. Additionally, variables such as stem cell graft granulocyte content and patient age, sex, and underlying disease, may be associated with hematopietic stem cell (HSC) infusion-related adverse reactions. In this study, we evaluated the correlation of preleukapheresis PB granulocyte count and PBSC harvest variables with CD34+ collection yield and efficiency, and thawed HSC infusion side effect occurrence...

There is an urgent need for 3D cell culture systems that avoid the oversimplifications and artifacts of conventional culture in 2D. However, 3D culture within the cavities of porous biomaterials or large 3D structures harboring high cell numbers is limited by the needs to nurture cells and to remove growth-limiting metabolites. To overcome the diffusion-limited transport of such soluble factors in 3D culture, mixing can be improved by pumping, stirring or shaking, but this in turn can lead to other problems...

This study's purposes were to diagnose intractable hemolytic anemia and to provide guiding treatment for the affected family members. We performed NGS in a panel of 600 genes for blood diseases on a patient with obscure hemolytic anemia and her parents. We confirmed the diagnosis of pyruvate kinase deficiency, identified a novel homozygous mutation of the PKLR gene (NM_000298: exon 6: c.T941C: p.I314T), and ruled out other blood diseases in the Chinese family. Furthermore, amniotic fluid was taken from the mother during the second trimester, and DNA was extracted to analyze the type of PKLR gene mutation...

Total body irradiation (TBI) is frequently used in hematopoietic stem cell transplantation (HSCT) and is associated with many complications due to radiation injury to the normal cells, including normal stem cells. Nevertheless, the effects of TBI on the mesenchymal stromal stem cell (MSC) are not fully understood. Bone marrow-derived MSCs (BM-MSCs) isolated from normal adults were irradiated with 200 cGy twice daily for consecutive 3 days, a regimen identical to that used in TBI-conditioning HSCT. The characteristics, differentiation potential, cytogenetics, hematopoiesis-supporting function, and carcinogenicity of the irradiated BM-MSCs were then compared to the non-irradiated control...

Chemotherapeutic drug treatment can result in the emergence of drug-resistant cells. By culturing an interleukin-3 (IL-3)-dependent cell line, FL5.12 cells in the presence of the chemotherapeutic drug doxorubicin, we isolated FL/Doxo cells which are multi-drug resistant. Increased levels of drug efflux were detected in FL/Doxo cells which could be inhibited by the MDR1 inhibitor verapamil but not by the MRP1 inhibitor MK571. The effects of TP53 and MEK1 were examined by infection of FL/Doxo cells with retroviruses encoding either a dominant negative TP-53 gene (FL/Doxo+ TP53 (DN) or a constitutively-activated MEK-1 gene (FL/Doxo + MEK1 (CA)...

Hematopoietic stem cell transplantation (HSCT) is being increasingly explored as a treatment modality for older patients with acute lymphoblastic leukemia (ALL). Yet, concerns regarding the long term outcome of transplantation in older patients limit the wide spread applicability of this approach. In this analysis we set out to determine the outcome of ALL patients over the age of 60 who underwent reduced intensity HSCT. Herein, we present the experience of the acute leukemia working party (ALWP) of the EBMT in this age group...

The regenerative capacity of hematopoietic stem cells (HSCs) is limited by the accumulation of DNA damage. Conditional mutagenesis of the histone 3 lysine 4 (H3K4) methyltransferase, Setd1a, revealed that it is required for the expression of DNA damage recognition and repair pathways in HSCs. Specific deletion of Setd1a in adult long-term (LT)-HSCs is compatible with adult life and has little effect on the maintenance of phenotypic LT-HSCs in the bone marrow. However, SETD1A-deficient LT-HSCs lose their transcriptional cellular identity accompanied by loss of their proliferative capacity and stem cell function under replicative stress in situ and after transplantation...

The Iroquois homeodomain transcription factor gene IRX3 is expressed in the developing nervous system, limb buds, and heart, and transcript levels specify obesity risk in humans. We now report a functional role for IRX3 in human acute leukemia. Although transcript levels are very low in normal human bone marrow cells, high IRX3 expression is found in ∼30% of patients with acute myeloid leukemia (AML), ∼50% with T-acute lymphoblastic leukemia, and ∼20% with B-acute lymphoblastic leukemia, frequently in association with high-level HOXA gene expression...

The switch from fetal to adult hematopoietic stem/progenitor cells (HSPCs) is associated with profound changes in several genetic programs. Although HSPC ageing corresponds to alterations in Wnt signaling, relatively little is known about the relative roles of different Wnt signaling pathways in HSPC ontogeny. We hypothesized that proliferating fetal HSPCs would be more dependent on canonical β-catenin-dependent Wnt signaling when compared to quiescent adult bone marrow HSPCs. We have compared here Wnt signaling activities in murine fetal and adult HSPCs and demonstrate a shift from Wnt/β-catenin-dependent signaling in fetal liver HSPCs to more predominantly noncanonical Wnt/polarity signaling in adult HSPCs...

REVIEW
Deepa Bhartiya
Recent study by Deanne's group provides evidence that transplanted GFP positive bone marrow hematopoietic stem cells (HSCs) expressing CD45 do not regenerate the endometrium of irradiated mice. The results do not surprise us since global efforts to regenerate various organs by transplanting bone marrow (BM) mononuclear cells (presumably enriched for HSCs) have failed. HSCs can only regenerate/reconstitute BM as they are 'committed progenitors' that are specified from more primitive, CD45 negative stem cells...
