background: human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue. objective: the aim was to isolate human dental pulp stem cells (dpsc), periodontal ligament stem cells (pdlsc) and periapical follicle stem cells (pafsc) for their potential role in tissue regeneration. materials and methods: in this experimental s...

background: pancreatic islet transplantation has emerged as a promising treatment for type i diabetes. however, its efficacy is severely hampered due to poor islet engraftment and revascularization, which have been resulted to partially loss of transplanted islets. it has been shown that local delivery of vascular endothelial growth factor (vegf) could accelerate transplanted islet revasculariz...

background: antibiotic prophylaxis is usually used in allogenic stem cell transplantation, but its use in autologous stem cell transplantation (asct) is controversial. we evaluated the efficacy of ciprofloxacin prophylaxis in asct. materials and methods: to identify the efficacy of ciprofloxacin on the incidence of neutropenic fever and its complications, 72 patients had been admitted to talegh...

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...
