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...

spinal cord injury (sci) is one of the devastating conditions leading to functional and neurological deficits following road traffic accidents. to date, there is no definite treatment for repairing damaged spinal cord tissue. in this regard, cell therapy opens a new window in front of scientists by using different cells such as mesenchymal stem cells, olfactory ensheathing cells, schwann cells,...

conclusions according to the results of the present study, it can be concluded that adipose derived mscs can be cultured in serum-free media with no change in their differentiating capacity. this finding gives us a hope for future cell therapy studies and trials with little concern about zoonotic infections or immunological reaction. results the isolated cells showed adherent spindle shaped mor...

background: mesenchymal stem cells (mscs) are undifferentiated cells that can differentiate and divide to other cell types. transplantation of these cells to the different organs is used for curing various diseases. objective: the aim of this research was whether mscs transplantation could treat the sterile testes. materials and methods: in this experimental study, donor mscs were isolated from...
