objectives: graft versus host disease (gvhd) is a life threatening reaction in the stem cell transplantation process. nowadays cyclosporine is the most commonly utilized agent for gvhd prophylaxis and it has a major role in successful transplantation. cyclosporine has been applied for many years in this field but it could be stated that currently no general consensus is available for its optima...

introduction: despite achievement to complete remission (cr) with current treatments and new multiple chemotherapeutic agents in acute lymphoblastic leukemia (all) patients, the majority of them still relapse during long-term follow-up. the use of post- remission therapy will reduce early relapse in these cases, but the best option is still debatable. patients and methods: in this retrospective...

experimental and clinical studies have shown that intracoronary transplantation of autologous bone marrow mesenchymal stem cells (bmscs) has resulted in regenerated infarcted myocardium and improved left ventricular (lv) function.the aim of this pilot study was to assess the benefical effectsof intracoronary transplantation of bmsc in patients with oldmyocardial infarction (omi). autologous bms...

Background: We have recently shown that human embryonic (hESCs) and induced pluripotent stem cells (hiPSCs) can differentiate into advanced spermatogenic cells including round spermatids by in vitro culture (Easley et al., Direct differentiation of human pluripotent stem cells into haploid spermatogenic cells. Cell Reports 2, 440-446 2012) and also, in collaboration, that rhesus spermatogonial ...

objective: we evaluated structural and functional changes of fresh and frozen-thawed adult mouse spermatogonial stem cells following auto-transplantation into gamma-irradiated testes. materials and methods: in this experimental research, the right testes from adult mice (n=25) were collected, then sertoli and spermatogonial cells were isolated using two-step enzymatic digestion, lectin immobili...

Background: Sickle cell anemia (SCA) is an inherited monogenic disorder. The clinical symptoms of SCA are protean, including vaso-occlusion, hemolysis, early stroke, leg ulcers, multi-organ failure, and increased risk of premature death. Hematopoietic stem cell transplantation is the only treatment identified to reduce SCA-related organ damage. Unfortunately, graft rejection is a significant im...

background : guillain-barre syndrome is an unusual complication of hematopoietic stem cell transplantation but it is extremely rare after solid organ transplantation such as kidney or liver transplantation case report : a 48-year-old man, a case of kidney transplantation presented with generalized weakness in an ascending pattern. history and examination were compatible with the diagnosis of gu...

Spinal cord injury (SCI) is a debilitating disease which leads to progressive functional damages. Because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. Different cellular and molecular approaches were investigated in SCI animal models. Cellular transplantation of stem cells can potentially replace damaged tissue and provid...
