stem cell factor (scf) is a critical protein with key roles in the cell such as hematopoiesis, gametogenesis and melanogenesis. in the present study a comparative analysis on nucleotide sequences of scf was performed in humanoids using bioinformatics tools including ncbi-blast, mega6, and jbrowse. our analysis of nucleotide sequences to find closely evolved organisms with high similarity by ncb...

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...

conclusions in iran, hsct has been successfully adapted in routine clinical care. recently, new methods such as double cord blood and haploidentical transplantation have been used to treat many life-threatening diseases. results about 78.2% of the patients (2530 of 3237) remained alive between one to 211 months after stem cell transplantation. nearly, 21.8% (707) of our patients died after stem...

objective(s):the mesenchymal stem cells (mscs) have been introduced as appropriate cells for tissue engineering and medical applications. some studies have shown that topography of materials especially physical surface characteristics and particles size could enhance adhesion and proliferation of osteoblasts. in the present research, we studied the distinction effect of 30 and 60 μg/ml of zinc ...

objective: this study presents a simple method for isolation, expansion and purification of neonatal mouse spermatogonial stem cells. methods: we used enzymatic digestion to isolate a cell suspension of spermatogonia and sertoli cells from neonatal 2-day-old mice. the cells were cultured in dmem/f12 that contained 10% serum for two weeks. sertoli and spermatogonia cell characteristics were conf...
