stem cell-based therapies have recently opened up new horizons for treatment of various types of diseases including diabetes mellitus. however, long-term efficacy and safety of these novel modalities still remain a serious question. hereby, we aim to report the one-year follow-up results in the diabetic patients who underwent fetal liver-derived hematopoietic stem cell allotransplantation. fift...

abstract accumulation of gene changes and chromosomal instability in response to cellular dna damage lead to cancer. dna damage induces cell cycle checkpoints pathways. checkpoints regulate dna replication and cell cycle progression, chromatin restructuring, and apoptosis. checkpoint kinase 2 (chk2) is activated in response to dna lesions. atm phosphorylate chk2. the activated chk2 kinase can p...

spinal cord injury (sci) is a destructive condition that the cord can't send signals below the level of the injury. despite advances in the medical and surgical care of sci patients, no effective treatment exists for the neurological deficits of sci. cell therapy is a new approach for sci, and preclinical models demonstrate that cell transplantation can improve some secondary events throug...

amniotic epithelial cells (aecs) possess unique characteristics, which make them a suitable source for cell-based therapeutic strategies. aecs have stem cell properties with low-immunogenicity (due to expressing hla-g molecule and absence of mhc class i and ii antigens) and no ethical problems, as well as availability in sufficient numbers, which can be obtained from a placenta. we have recentl...

the b cell is a vital contributor to humoral immunity. the b cell-specific antigen cd20 is expressed during b cell development, starting at the pre-b cell level and persists through b cell differentiation, but is lost during terminal differentiation to plasma cells. rituximab is a monoclonal antibody that destroys both normal and malignant b cells that have cd20 on their surfaces and is therefo...

objective(s) clinical studies of treating traumatic brain injury (tbi) with autologous adult stem cells led us to examine the impression of a combination therapy. this was performed by intravenous injection of human umbilical cord matrix stem cell (hucmsc-wharton,s jelly stem cell) with bone marrow cell mobilized by granulocytecolony stimulating factor (g-csf) in rats injured with cortical comp...

to date, stem cell therapy is a novel treatment method especially in irreversible end organ damage. we present a case of a 21-yr-old man, who admitted in sina hospital, tehran university of medical sciences, iran with open left femur fracture following car accident. developing fat emboli syndrome led to cardiac arrest. despite of efforts to optimize supportive care and neuroprotective strategie...

spinal cord injury (sci) is a destructive event that often lead to permanent neurologic deficit. current clinical treatments are aimed at preventing secondary damage, promoting regeneration, and replacing destroyed spinal cord tissue, although effective treatments for sci remain limited. cell therapies for treating sci are promising therapy for replacing dead cells, neuroprotection and axon reg...
