background: periodontal ligament stem cells (pdlscs) are considered as a type of mesenchymal stem cell that is beneficial target for numerous clinical applications in periodontal tissue regeneration therapy. materials and methods: this study examined the effects of dexamethasone (dex) on human pdlscs in vitro. pdlscs obtained from the roots of patient’s teeth were cultured with dex (0.01 μm), a...

in this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hbmscs) into hepatocytes on a three-dimentional (3d) nanofibrous scaffold formed by poly (ε-caprolactone) (pcl), collagen and polyethersulfone (pes). the nanofiber was prepared by the electrospining technique. hbmscs were isolated using combining gradient density centrifugation ...

stem cells are the cells having some distinguishing characteristics like longevity, high capacity of self-renewal and differentiation, quiescence and highly error-free proliferation. almost all stem cells have the potential of lineage reprogramming, i.e. inter-conversion of cell lineages. they also have the potential to differentiate into almost all kinds of cells. these cells have been found i...

multiple sclerosis (ms) is an autoimmune inflammatory demyelinating disease of the central nervous system. the aim of this study was to investigate the neuroprotective effects of transplanted human umbilical cord blood mesenchymal stromal cells (ucb-msc) derived neural progenitor cell (mdnpc) in eae, an experimental model of ms. to initiate neuronal differentiation of ucb-mscs, the pre-inductio...

objective(s):transplantation quality improvement and reduction of cellular damage are important goals that are now considered by researchers. melatonin is secreted from the pineal gland and some organs such as testes. according to beneficial effects of melatonin (such as its antioxidant and antiapoptotic properties), researchers have proposed that the use of melatonin may improve transplantatio...

objective(s) bone marrow is the traditional source of human multipotent mesenchymal stem cells (mscs), but adipose tissue appears to be an alternative and more readily available source. in this study, rat adipose-derived stem cells (adscs) were induced to differentiate into schwann-like cells and compared with rat bone marrow stem cells (bmscs) for their schwann-like cells differentiation poten...

objective(s) it is believed that the mesenchymal stem cell (msc) differentiation and proliferation are the results of activation of wnt signaling pathway. on the other hand, lithium chloride is reported to be able to activate this pathway. the objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived msc. materials and ...

background: characteristics of differentiated osteoblasts from adipose derived stem cells (adscs) in compared with isolated osteoblasts from normal bone such as calvaria are unknown. the aim of this study was determination and comparison of phenotypic characterization between differentiated osteoblasts from stem cells and calvaria osteoblasts in vitro . methods: in this study, mesenchymal stem ...
