Islets from xeno-sources and islet like clusters derived from autologus stem cells have emerged as alternatives to cadaveric pancreas used for treatment of type 1 diabetes. However, the immuno-isolation of these islets from the host immune system suffers from the issue of biocompatibility and hypoxia. To overcome the issues of immunobarrier biocompatibility, we developed a Polysulfone (Psf)/TPGS composite hollow fiber membrane (HFM) using a hollow fiber spinning pilot plant specially developed for this purpose...

Transplantation of bone marrow derived stem cells (BMSCs) has been reported inhibits liver fibrosis. Several in vitro studies by co-culturing BMSCs and hepatic stellate cells (HSCs) indirectly or directly in 2D models showed inhibition of HSC as the key player in liver fibrosis. In this study, we investigated direct effect of BMSCs on HSCs by co-culturing BMSCs and HSCs in 3D model as it represents the liver microenvironment with intricate cell-cell and cell-matrix interactions. Primary isolated rat HSCs and BMSCs were directly co-cultured at 1:1 ratio with hanging drop method...

Bone marrow derived mesenchymal stem cells (MSCs) play a critical role in immune modulation. However, immunomodulatory function of whole human umbilical cord derived mesenchymal stem cells (UC-MSCs) remains unclear. In this study, UC-MSCs were separated from whole umbilical cord using a single enzyme digestion. UC-MSCs (CD73(+), CD90(+), CD105(+), and CD34(-), CD45(-), HLA-DR(-)) were differentiated into adipocytes, osteocytes and chondrocytes in vitro under specific stimulatory environments. UC-MSCs suppressed umbilical cord blood lymphocyte proliferation stimulated by mitogen, and ELISA showed that the secretion of INF-γ was downregulated, and the secretion of IL-4 was upregulated, with CD8(+) T cells markedly decreased and CD4(+) T cells changed lightly...

Systemic sclerosis (SSc) is a rare disabling autoimmune disease with a similar mortality to many cancers. Two randomized controlled trials of autologous hematopoietic stem cell transplantation (AHSCT) for SSc have shown significant improvement in organ function, quality of life and long-term survival compared to standard therapy. However, transplant-related mortality (TRM) ranged from 3-10% in patients undergoing HSCT. In SSc, the main cause of non-transplant and TRM is cardiac related. We therefore updated the previously published guidelines for cardiac evaluation, which should be performed in dedicated centers with expertize in HSCT for SSc...

Relapse remains the most common cause of treatment failure in patients receiving autologous stem cell transplantation (ASCT) for follicular lymphoma (FL). The aim of this study was to evaluate the effect of adding radioimmunotherapy or rituximab (R) to BEAM (carmustine, etoposide, ara-c, melphalan) high-dose therapy for ASCT in patients with relapsed FL. Using the European Society for Blood and Marrow Transplantation registry, we conducted a cohort comparison of BEAM (n=1973), Zevalin-BEAM (Z-BEAM) (n=207) and R-BEAM (n=179) and also a matched-cohort analysis of BEAM vs Z-BEAM including 282 and 154 patients, respectively...

BACKGROUND: Despite encouraging data in terms of neurological outcome, stem cell based therapy for ischemic stroke in experimental models and human patients is still hampered by multiple as yet un-optimized variables, i.e., time of intervention, that significantly influence the prognosis. The aim of the present study was to delineate the optimum time for neural stem cells (NSCs) transplantation after ischemic stroke. METHODS: The NSCs were isolated from 14 days embryo rat ganglion eminence and were cultured in NSA medium (neurobasal medium, 2% B27, 1% N2, bFGF 10 ng/mL, EGF 20 ng/mL and 1% pen/strep)...

Ischemic heart disease remains one of the most prominent causes of mortalities worldwide with heart transplantation being the gold-standard treatment option. However, due to the major limitations associated with heart transplants, such as an inadequate supply and heart rejection, there remains a significant clinical need for a viable cardiac regenerative therapy to restore native myocardial function. Over the course of the previous several decades, researchers have made prominent advances in the field of cardiac regeneration with the creation of in vitro human pluripotent stem cell-derived cardiomyocyte tissue engineered constructs...

Rationale: Patients receiving an allogeneic stem cell graft from cytomegalovirus (CMV) seronegative donors are particularly prone to CMV reactivation with a high risk of disease and mortality. Therefore we developed and manufactured a novel vaccine and initiated a clinical phase I trial with a CMV phosphoprotein 65 (CMVpp65)-derived peptide. Methods: Ten patients after allogeneic stem cell transplantation received four vaccinations at a biweekly interval. All patients were monitored for CMVpp65 antigenemia...

Cancer stem cells or tumor-initiating cells (TICs) are a small subpopulation of cells that have the capacity to self-renew, differentiate and initiate tumors. These cells may function in tumor initiation, aggression and recurrence. Whether spheres derived from canine rhabdomyosarcoma cells have stem cell-like properties is unclear. We induced sphere formation in the canine rhabdomyosarcoma cell lines, CMS-C and CMS-J, and characterized the spheres in vitro and in vivo. Sphere-forming cells were more resistant to vincristine, mitoxantrone and doxorubicin than adherent cells...

The discovery of induced pluripotent stem cells (iPSCs) has revolutionized regenerative medicine. Autologous iPSCs can be generated by introducing 4 stem cell-specific factors (Oct4, Sox2, Klf4, c-Myc) into fibroblasts. iPSCs can propagate indefinitely and differentiate into clinically important cell types including cardiomyocytes, in vitro. The iPSC-derived cardiomyocytes represent a promising source of cells for cell-based therapeutic approaches for cardiac regeneration. However, there are several challenges in the clinical application of iPSCs: tumorigenicity of immature cells, poor survival of the transplanted myocardial cells, and cost and efficacy of this therapeutic approach...

It has long been believed that most female mammalian species lose the ability to generate oocytes in postnatal ovaries. Recent evidence has demonstrated the isolation and culture of female germline stem cells (FGSCs) from adult mice and humans. However, the process and mechanisms of FGSC differentiation in vivo following transplantation have not yet been studied. Here, we isolated and characterized FGSCs from a single EGFP-transgenic mouse, and traced the development and behavior of transplanted FGSCs (F-TFs) in vivo...

INTRODUCTION: Most common source of stem cell graft for both autologous and allogenic haematopoietic transplants are peripheral blood haematopoietic progenitor stem cells. Adequate collection of the CD34+ cells and safety of the allogenic donor during the leukapheresis are of prime importance to an apheresis physician. Our retrospective analysis is a comparison between of two platforms namely, COBE Spectra and Amicus, for CD34+ mononuclear cell collection. MATERIAL AND METHOD: The study included the data of GSCF (Granulocyte-Colony-Stimulating Factor) mobilized allogenic PBSC collections at our centre from January 2015 to June 2016...

During the last years, a significant increase in infections caused by multidrug-resistant organisms (MDRO) has been noticed, resulting in an increase of mortality in all fields of healthcare. Hematological patients are particularly affected by MDRO infections due to disease- and therapy-related immunosuppression. To determine the impact of colonization with MDRO on overall survival, we retrospectively analyzed data from patients undergoing autologous hematopoietic stem cell transplantation at our institution...

Recent reports have documented the differentiation of human pluripotent stem cells toward the skeletal myogenic lineage using transgene- and cell purification-free approaches. Although these protocols generate myocytes, they have not demonstrated scalability, safety, and in vivo engraftment, which are key aspects for their future clinical application. Here we recapitulate one prominent protocol, and show that it gives rise to a heterogeneous cell population containing myocytes and other cell types. Upon transplantation, the majority of human donor cells could not contribute to myofiber formation...

Recent studies using defined transcription factors to convert skin fibroblasts into chondrocytes have raised the question of whether osteo-chondroprogenitors expressing SOX9 and RUNX2 could also be generated during the course of the reprogramming process. Here, we demonstrated that doxycycline-inducible expression of reprogramming factors (KLF4 [K] and c-MYC [M]) for 6 days were sufficient to convert murine fibroblasts into SOX9(+)/RUNX2(+) cellular aggregates and together with SOX9 (S) promoted the conversion efficiency when cultured in a defined stem cell medium, mTeSR...

In patients with relapsed or refractory (r/r) AML, allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is considered to be the only treatment providing long-term disease control. The BRIDGE trial studied the safety and efficacy of a clofarabine-based salvage therapy prior to HSCT in patients with r/r AML. Here, we report the long-term follow up of this Phase II, multi-center trial and exploratory analyses on the impact of comorbidity on outcome.

Granulocyte colony-stimulating factor (G-CSF) is routinely used in the clinic to mobilize hematopoietic stem progenitor cells (HSPC) into the patient's blood for collection and subsequent transplantation. However a significant proportion of patients who have previously received chemotherapy or radiotherapy and requiring autologous HSPC transplantation, cannot mobilize the minimal threshold of mobilized HSPC to achieve rapid and successful hematopoietic reconstitution. Although several alternatives to the G-CSF regime have been tested, few are in use in the clinic...
