background: cell therapy has emerged as a promising curative intervention for several diseases including diabetes and wolfram syndrome (ws). the current study aimed to assess the effectiveness of clinical application of fetal-liver derived stem cells for treatment of patients with ws. methods: six patients with ws aged 23-34 (mean: 29.50, sd: 4.76) were recruited for the current phase 3 single-...
Hematopoietic stem cells (HSCs) are unique in their capacity to maintain blood formation following transplantation into immunocompromised hosts. Expansion of HSCs in vitro is therefore important for many clinical applications but has met with limited success because the mechanisms regulating the self-renewal process are poorly defined. We have previously shown that expression of the LIM-homeobo...
Stem cell therapies may be valuable in treatment of inflammatory bowel disease (IBD). Here we focus on two very different types of stem cells - hematopoietic stem cells and mesenchymal stem cells. Myeloablation and hematopoietic stem cell transplantation alter host immune response by reconstituting the recipient's blood cell lines with donor cells. Autologous hematopoietic reconstitution may "r...
BACKGROUND Currently, hematopoietic stem cell transplantation is still an essential treatment approach for leukemia. However, patients with leukemia often have weakened immune function, especially more seriously compromised cellular immune response, and appear to be at greater risk for tuberculosis infection during the transplantation process. We aimed to investigate the efficacy and safety of ...
post-remission treatment in patients with acute myeloid leukemia is still controversial. one potent choice for patients with no donor available is autologous stem cell transplantation. the median follow-up period was 18 months and the median age was 26 years old. in the review of 116 recently diagnosed aml patients (except aml- m3) who underwent autologous stem cell transplantation, 72.4% of pa...
purpose: to report the outcomes of conjunctival-limbal autograft (clau) in patients with unilateral total limbal stem cell deficiency (lscd) emphasizing surgical problems, complications, and their management. methods: in this prospective interventional case series, clau combined with amniotic membrane transplantation as a graft was performed on 26 patients with unilateral total lscd due to chem...
many investigators have used xenogeneic, especially murine stromal cells and fetal calf serum to maintain and expand human stem cells. the proliferation and expansion of human hematopoietic stem cells in ex vivo culture were examined with the goal of generating a suitable protocol for expanding hematopoietic stem cells for patient transplantation. using primary fetal liver cells, we established...
CD4 regulatory T cells play a critical role in establishment of immune tolerance and prevention of graft-versus-host disease after allogeneic hematopoietic stem cell transplantation. The recovery and maintenance of regulatory T cells is dependent on homeostatic factors including the generation of naïve regulatory T cells from hematopoietic precursor cells, the proliferation and expansion of mat...
In utero hematopoietic stem cell transplantation (IUHCT) is an attractive approach and a potentially curative surgery for several congenital hematopoietic diseases. In practice, this application has succeeded only in the context of Severe Combined Immunodeficiency Disorders. Here, we review potential immunological hurdles for the long-term establishment of chimerism and discuss relevant models ...
Blood cells transplantation is largely replacing bone marrow transplantation because engraftment is more rapid. This accelerated engraftment is thought to be mediated by relatively mature committed hematopoietic progenitor cells. Herein, we have used a modified rhodamine (Rho) staining procedure to identify and purify Rho+/++ (dull/bright) and Rho- (negative) subpopulations of hematopoietic pro...
