In our retrospective study, 16 patients affected by advanced cutaneous T cell lymphoma (CTCL) underwent allogeneic hematopoietic stem cell transplantation (HSCT). Two patients (12.5%) were in complete remission (CR), nine (56.3%) in partial remission (PR), and five (31.2%) with active disease. The patients were transplanted from an HLA-identical (n = 7) from a mismatched (n = 1) or haploidentical (n = 1) sibling, from matched unrelated donor (n = 5), or from a single cord blood unit (n = 2). Conditioning regimen was standard myeloablative in 6 patients and at reduced intensity in 10...

Nicholas A Zumwalde, Jenny E Gumperz
Mice engrafted with human immune cells offer powerful in vivo model systems to investigate molecular and cellular processes of tumorigenesis, as well as to test therapeutic approaches to treat the resulting cancer. The use of umbilical cord blood mononuclear cells as a source of human immune cells for engraftment is technically straightforward, and provides T lymphocytes and autologous antigen-presenting cells (including B cells, monocytes, and DCs) that bear cognate antigen presenting molecules. By using a human-specific oncogenic virus, such as Epstein-Barr virus, de novo neoplastic transformation of the human B cells can be induced in vivo in a manner that models progressive stages of tumorigenesis from nascent neoplasia to the establishment of vascularized tumor masses with an immunosuppressive environment...

STUDY QUESTION: Has PGD-HLA been successful relative to diagnostic and clinical efficacy? SUMMARY ANSWER: The diagnostic efficacy of PGD-HLA protocols was found lower in this study in comparison to published PGD-HLA protocols and to that reported for general PGD by ESHRE (78.5 vs 94.1% and vs 92.6%, respectively), while the clinical efficacy has proven very difficult to assess due to inadequate follow-up of both the ART/PGD and HSCT procedure outcomes. WHAT IS KNOWN ALREADY: The first clinical cases for PGD-HLA were reported in 2001...

BACKGROUND AND AIM OF THE WORK: Hepatocellular carcinoma (HCC) is the most frequent primary liver malignancy. Chronic liver injuries as chronic hepatitis C and hepatitis B viruses, aflatoxins consumption and nonalcoholic fatty liver disease are well-established causes of HCC. HCC is associated with a series of molecular changes, as alternation in glypican-3, P53 expression and Wnt/β-catenin pathway. Hepatic cancer progenitor cells could contribute to HCC development. This research aimed to study the effectiveness of human CD34+ hematopoietic stem cell on Wnt4 and P53 genes expression, histopathological grading and hepatic progenitor cells percentage in HCC rat model...

Mycophenolate mofetil (MMF) is a pro-drug of mycophenolic acid (MPA) and is frequently used to prevent acute graft-versus-host disease (aGVHD) in patients receiving hematopoietic stem cell transplants (HCT). However, optimal doses of MMF and target MPA concentrations in HCT patients have not been defined. In this study, relationships between pharmacokinetic or pharmacodynamic markers of MPA and successful aGVHD prevention and neutrophil engraftment were evaluated to inform individualized MPA treatments in HCT patients...

Umbilical cord blood stem cell transplantation (UCBT) is associated with retarded hematopoietic recovery and immune reconstitution and a high infection-related morbidity and mortality, especially after conditioning including anti-thymocyte globulin (ATG). However, data on immune recovery, incidence of infections, and outcome in double UCBT (dUCBT) recipients receiving an ATG-free reduced intensity conditioning (RIC) are lacking. In this study, recovery of lymphocyte subsets, thymopoiesis, and its association with severe infections and clinical outcome was assessed in a group of 55 recipients of a dUCBT ATG-free RIC regimen...

Hematopoietic cell transplantation (HCT) is a treatment for malignant and non-malignant disorders. However, sometimes the numbers of donor hematopoietic stem cells (HSC) are limiting, which can compromise the success of HCT. We recently published that collection and processing of mouse bone marrow (BM) and human cord blood cells in a hypoxic atmosphere of 3% O2 or in ambient air (~21% O2) in the presence of cyclosporine A yields increased numbers of HSC. We now show that collection and processing of mouse BM cells in ambient air in the presence of specific combinations of anti-oxidants and/or inhibitors of epigenetic enzymes can also enhance the collection of HSC, information of potential relevance for enhanced efficacy of HCT...

Neonatal traumatic brain injury (TBI) is a significant cause of developmental disorders. Autologous stem cell therapy may enhance neonatal brain plasticity towards repair of the injured neonatal brain. Areas Covered: The endogenous neonatal anti-inflammatory response can be enhanced by biological treatments. Stem cell therapy stands as a robust approach for sequestering the inflammation-induced cell death in the injured brain. Here, we discuss the use of umbilical cord blood cells and bone marrow stromal cells for acute and chronic treatment of experimental neonatal TBI...

CD34 is a transmembrane phosphoglycoprotein used to selectively enrich bone marrow in hematopoietic stem cells for transplantation. Treating rats with CD34+ cells derived from human umbilical cord blood before or after heat stroke has been shown to promote survival. We investigated whether CD34- human placenta-derived stem cells (PDMSCs) could improve survival following heat stroke in rats. Rats were subjected to heat stress (42°C for 98 min) to induce heat stroke. Intravenous administration of PDMSCs 1 day before or immediately after the onset of heat stroke improved survival by 60% and 20%, respectively...

A 9-year-old girl was referred to our hospital because of facial palsy. Both physical and blood examination revealed hepatosplenomegaly and leukocytosis, respectively. A bone marrow examination demonstrated marked hypercellularity involving myeloblasts and lymphoblasts. Based on these results, we suspected mixed phenotype acute leukemia. However, her leukemic blasts expressed B-cell antigens, and a chromosomal analysis of her bone marrow cells revealed the following karyotype: 46, XX, t (9;22) (q34;q11.2). All her neutrophils were positive for the breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 fusion protein...

Allogeneic hematopoietic stem cell transplantation is recommended as a curative treatment option for fulminant aplastic anemia with no neutrophil despite the administration of granulocyte-colony stimulating factor. In the absence of an HLA-matched donor, unrelated cord blood transplantation (UCBT) is a treatment option that can be performed quickly. However, the optimal conditioning regimen of UCBT is yet to be established. We report two cases of fulminant aplastic anemia in adult patients who received UCBT...

The poor prognosis of extramedullary recurrence of acute leukemia following allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains a therapeutic challenge, and thus far no effective treatment method has been established. Here, we report two patients who presented with relapsed leukemia as extramedullary tumor in the ovary following allo-HSCT. Case 1: A 23-year-old female underwent unrelated allogeneic bone marrow transplantation during the second remission of acute myeloid leukemia. After 706 days post-transplant, bilateral ovarian tumors were detected during the pelvic ultrasound, and extramedullary recurrence in the bilateral ovaries was subsequently established on right salpingo-oophorectomy and biopsy of the left ovary...

The possibility to use CCR5-∆32 umbilical cord blood to cure HIV infection in patients in need of a hematopoietic transplant has been suggested. The less stringent HLA compatibility needed in this type of transplant facilitates the search of a suitable donor having the CCR5-∆32 mutation. To achieve an inventory of CCR5-∆32 cord blood units, the 20,236 best cell quality units of the Spanish Registry were genotyped. Furthermore, their CD34 + and total nucleated cells counts, blood type, gender, HLA and donor's geographical and ancestral origin were analyzed...

A novel induction therapy, including intensive L-asparaginase, was designed in 2007 for patients aged <45 years with Philadelphia-negative acute lymphoblastic leukemia (ALL). We analyzed seven de novo cases and one case of recurrence who received this treatment. The median age was 21 years (range: 16-35 years). Four patients had T-ALL and the others had B-ALL. All the patients achieved complete remission and proceeded to cord blood transplantation. In the median 72-month follow-up, there were no cases of observed mortality or recurrence...

PURPOSE OF STUDY: Patients with neonatal urea cycle defects (UCDs) typically experience severe hyperammonemia during the first days of life, which results in serious neurological injury or death. Long-term prognosis despite optimal pharmacological and dietary therapy is still poor. The combination of intravenous sodium phenylacetate and sodium benzoate (Ammonul®) can eliminate nitrogen waste independent of the urea cycle. We report attempts to improve outcomes for males with severe ornithine transcarbamylase deficiency (OTCD), a severe X-linked condition, via prenatal intravenous administration of Ammonul and arginine to heterozygous carrier females of OTCD during labor...

Umbilical cord blood (UCB) transplants in adults have slower hematopoietic recovery compared to bone marrow (BM) or peripheral blood (PB) stem cells mainly due to low number of total nucleated cells and hematopoietic stem and progenitor cells (HSPC). As such in this study, we aimed to perform ex vivo expansion of UCB HSPC from non-enriched mononucleated cells (MNC) using novel azole-based small molecules. Freshly-thawed UCB-MNC were cultured in expansion medium supplemented with small molecules and basal cytokine cocktail...
