introduction demyelination is a common lesion of spinal cord injury; cell therapy is an approach for replacing the lost oligodendrocytes. objective in this study, bone marrow stromal cells (bmscs) have been transdifferentiated into oligodendrocyte-like cells (olcs) and used in cytotherapy of contused spinal cords in rats. materials and methods the bmscs were collected from rat long bones, cultu...

background: langerhans' cell histiocytosis (lch) is a reactive proliferative disease of unknown pathogenesis characterized by proliferation of langerhans cells. involvement of bone marrow (bm), liver and lung are related to high risk factors and poor survival. the aim of this report is to highlight the clinical and haematological findings of 5 cases of lch with bm infiltration which may help to...

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...

introduction: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can increase axonal regeneration in peripheral nerve injuries. based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . we pursued to evaluate the effects of bmscs and scs co-transplant...

it is estimated that annually 10 million people are affected by traumatic brain injury and it is one of the major causes of death and disability in accidents. studies have shown the potential therapeutic value of neural stem cell therapies. also, neural stem cell motility and migration to the site of injury has a great regeneration value of the damaged tissues. extracellular and intracellular f...

background: bone marrow-derived mesenchymal stem cells (bmmscs) transplantation has been considered as a promising milestone in liver fibrosis treatment. however, low amounts of homing are a major obstacle. we aimed to investigate the role of melatonin pretreatment in bmmsc homing into experimental liver fibrosis. methods: bmmscs were obtained, grown, propagated and preconditioned with 5 µm mel...

conclusions the results of this study showed that the meticulous microsurgical nerve repair, which was performed using the vein tubulization induced significantly better sciatic nerve regeneration. however, the addition of bone marrow mesenchymal stem cell to vein conduit failed to promote any significant changes in regeneration outcome. results all animals tolerated the surgical procedures and...

background: silk fibroin is a suitable protein for osteogenesis by inducing markers of bone formation in the cultures of osteoblasts, so we examined the ability of this protein to induce mineralized nodules in the rat bone marrow stromal cell cultures. methods: bone marrow stromal cells obtained from 4 to 6 weeks old spruge-dawely male rats were grown in primary culture for seven days and then ...

introduction: sox9 is a transcriptional activator which is necessary for chondrogenesis. sox6 are closely related to dna-binding proteins that critically enhance its function. therefore, to carry out the growth plate chondrocyte differentiation program, sox9 and sox6 collaborate genomewide. chondrocyte differentiation is also known to be promoted by glucocorticoids through unknown molecular mec...

introduction: bone marrow (bm) is a known source of mesenchymal stem cells (mscs) that are used for cell therapy. this study attempts to identify if the wharton’s jelly (wj) is a suitable substitute for bm as a source for mscs. materials and methods: a population of human wj and bm stem cells were isolated and incubated with fluorescein conjugated antibodies for five specific msc markers. cell ...
