multiple sclerosis (ms) is an autoimmune disease, which is characterized by demyelination and neuroinflammation. extracellular matrix (ecm) have important role in the central nervous system (cns). alterations are happening to the ecm after the cns disorder like ms, alzheimer and other neural injury. tenasin-c (tnc) is a glycoprotein that is highly expressed in inflammatory conditions of the cns...

background: stem cell factor (scf) is a transcriptional factor which plays crucial roles in normal proliferation, differentiation and survival in a range of stem cells. objective: the aim of the present study was to examine the proliferation effect of different concentrations of scf on expansion of human endometrial cd146+ cells. materials and methods: in this experimental study, total populati...

background: limited resources for adult stem cells necessitate their in vitro culture prior to clinical use. investigating mitochondrial dna (mtdna) and telomere shortening has proved to be important indications of stem cell validity. this study was designed to investigate these indicators in multiple passages of three adult stem cell lines which were produced in our stem cell laboratory. metho...

The complexity of multiple sclerosis (MS) and the incompetence of a large number of promise treatments in MS urge us to plan new and more effective therapeutic approaches that aim to suppress ongoing autoimmune responses and induction of local endogenous regeneration. Emerging data propose that hematopoietic, mesenchymal and neural stem cells have the potential to restore self-tolerance, to pro...

stem cell-based therapy has great potential in treating health conditions including cardiovascular, autoimmune, type i diabetes, neurodegenerative and bone and cartilage diseases also in spinal cord injuries, malformations and cancer. in addition to their potential use to treat systemic diseases, stem cell-based therapy also provides a powerful tool to treat oral and dental diseases such as cra...

background: the cultured mesenchymal stem cells (msc) have been used in many clinical trials however, there are still some concerns about the cultural conditions. one concern is related to the use of fbs as a widely used xenogeneic supplement in the culture system. human platelet-rich plasma (hprp) is a candidate replacement for fbs. in this study, the effect of hprp on msc proliferation and os...

objective(s): sertoli cells support in vivo germ cell production; but, its exact mechanism has not been well understood. the present study was designed to analyze the effect of sertoli cells in differentiation of mouse embryonic stem cells (mescs) to germ cells.   materials and methods: a fusion construct composed of a stra8 gene promoter and the coding region of enhanced green fluorescence pro...

nowadays, scientific c findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. magnetic resonance ima...

background: human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue. objective: the aim was to isolate human dental pulp stem cells (dpsc), periodontal ligament stem cells (pdlsc) and periapical follicle stem cells (pafsc) for their potential role in tissue regeneration. materials and methods: in this experimental s...
