background: creation of artificial gametes may provide a universal solution for these patients of lacking gametes. stem cell technology may provide a way to obtain fully functional gametes. retinoic acid (ra) can initiate meiosis. several studies have demonstrated that ra can promote sperm cells differentiation from mouse embryonic stem cells (mescs) and other cells from human embryonic stem ce...
stem cells are cells with the ability to divide for indefinite periods and to give rise to specialized cells. stem cell therapy has now been emerged as an extraordinary promise to treat a wide range of diseases and conditions. however, except blood stem cell transfer by bone marrow transplant which has been used as an standard practice for more than 50 years, nearly all of therapeutic potenti...
abstract background: recently, stem cells have been used to facilitate healing in animal models of renal failure induced by acute ischemic and nephrotoxic damage. granulocyte colony-stimulating factor (g-csf) has been reported to stimulate stem cell mobilization from bone marrow and these cells may contribute to renal repair. objectives: in the present study, the effects of g-csf and stem cell ...
mast cells play an important role in a variety of inflammatory diseases, particularly asthma and atopy. peroxisome proliferator-activated receptor gamma (pparγ) is a member of the large nuclear hormone receptor transcription factor superfamily, and has been recently implicated in the anti-inflammatory response. to investigate a possible role for pparγ in human mast cells, we studied the ...
arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...
introduction: allogeneic hematopoietic cell transplantation (hsct) is the only therapeutic modality capable of correcting the hematologic manifestations of fanconi anemia (fa). the development of well tolerated, immunosuppressive conditioning regimens for fa patients undergoing hsct has proven to be a rather challenging task for hematologists. methods: we analyzed the outcome of 30 fa pa...
introduction: stromal cells having preadipocyte characteristics can be isolated from adipose tissue, propagated in vitro and induced to differentiate in vitro toward the osteogenic, adipogenic, myogenic and chondrogenic lineages when treated with established lineage-specific factors. in this research we isolated stromal cells from human adipose tissue and cultured and expanded and examined thei...
background : many types of cancer cells require a supply of fatty acids (fa) for growth and survival, lpl, in the presence of triglyceride-rich lipoproteins, accelerates the growth of these cells. recent evidence shows that lpl plays important roles in inflammation and obesity, implies that it is an appropriate general target for chemo preventive and chemotherapeutic agents. thus, we reported l...
purpose: to evaluate stem cell deficiency using impression cytology (ic) in patients with chronic and delayed-onset mustard gas keratopathy (mgk). methods: a consecutive series of patients with mgk underwent ic. thirty-five eyes of 18 patients (all male) with mustard gas keratopathy were included in this observational case series. presence of goblet cells on the corneal side of specimens was co...
the prevalence of spinal cord injury (sci) is about 2.5 million in the worldwide and more than 130,000 new injuries reported each year. regeneration in the cns versus the pns is very different from the other tissues and many factors can prevent regeneration in pns and specially cns. previous researches demonstrated that regeneration of cns can inhibit by inhibitory molecules and glial scar. the...
