background: despite the extensive information available in the literature, cell surface marker signature of human amniotic epithelial cells (haecs) remains controversial. the aim of the present study was to characterize immuno-phenotypic features, proliferative capacity and immunogenicity of haecs. we also tested whether expression of some cell surface markers is influenced by the type of tryps...

isolated extramedullary relapse of chronic myelogenous leukemia (cml) after allogeneic stem cell transplant is rare. there is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for cml. he was presented with per orbital edema and neurological deficit of lower extre...

background: hematopoietic stem cell transplantation (hsct) is currently the only curative treatment for acute leukemia. as hsct improves the long-term survival, it is necessary to assess the late-onset complications affecting the quality of life following hsct. subjects and methods: the study included 122 patients (65 male, 57 female) with leukemia (72 aml and 50 all) who received transplants f...

introduction: severe acquired aplastic anemia (saa) is a rare disease and matched related hematopoietic stem cell transplantation (hsct) is the treatment of choice especially in pediatric patients. immunosuppressive therapy is the alternative treatment in patients who do not have a donor. we retrospectively analyzed patients who received allogeneic hsct at our institution. methods: between 1991...

introduction: zinc (zn) deficiency can cause significant defects in cellular immunity. hematopoietic stem cell transplantation (hsct) patients usually experience serious deficiencies of all components of the immune system. therefore, the maintenance of a normal zn status may be important in this group of patients. patients and methods: serum zn levels were analyzed in 55 patients during the hsc...

the most important factor in donor-recipient matching for hematopoietic stem cell transplantation is their hla typing. for many patients, we can not find a full-matched donor. in high risk patients, one locus  mismatched related donors are suitable alternatives. (1, 2) since the matching of patients and their siblings usually is based on low resolution hla typing, the matching of one locus mism...

introduction: acute myelogenous leukemia (aml) is a clonal  malignant disease of hematopoietic tissue. the early use of  hematopoietic stem cell transplantation (hsct) for aml was for patients with advanced stages of disease, usually while in relapse, in second or subsequent remission, or with resistant disease. patients and methods: from march 1991 until february 2008, 356(65%) registered allo...

from 1996 to 2002, fifty three patients with major beta-thalassemia received allogeneic peripheral blood stem cell trans plantation (pbsct). median age was 6 years .twenty two were class i, 17 class ii and 14 class iii. all of the donors were hla-identical. conditioning regimen for class i and ii patients consisted of cyclophosphamide (cy) 50 mg/kg/day for 4 days + busulfan (bu) 3.5 mg/kg for 4...

we are describing a new surgical approach in the management of advanced ocular surface cicatrization through a single procedure conjunctival-limbal-corneal allograft in which the external eye is resurfaced it involves a lamellar corneolimbal keratoplasty, 360° limbal stem cell transfer (on a “bipedicle” conjunctival-corneal carrier), and conjunctival tissue transplantation - all in a single con...

background: bone marrow-derived mesenchymal cellscan transdifferentiate into cardiomyocyte cells and improveheart function after transplantation. since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. ch...
