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 ...

PURPOSE Efficacy of cultivated oral mucosa epithelial transplantation (COMET) procedure in corneal epithelium restoration of aniridia patients. METHODS Study subjects were aniridia patients (13 patients; 17 eyes) with irregular, vascular conjunctival pannus involving visual axis who underwent autologous transplantation of cultivated epithelium. For the procedure oral mucosa epithelial cells w...

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...

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...
