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...
the purpose of the present study is to investigate the prevalence of th17 and regulatory t (treg) cells in children with allergic rhinitis (ar) accompanying with bronchial asthma (ba).24 children with ar, 22 children with ba, 18 children with ar accompanying with ba,and 20 healthy controls were recruited. the prevalence of peripheral blood th17 and treg cells were determined by flow cytometry. ...
background: umbilical cord tissue is a very rich source of mesenchymal stem cells. instead of discarding this source we are banking the tissue along with cord blood for possible future cell based applications. the cord tissue needs to be transported and stored properly in order for it to be good enough for cell isolation at a later date. in this paper we have carried out a validation study to d...
background: despite the extensive information available in the literature, cell surface marker signature of human amniotic epithelial cells (haecs) remains controversial. the aim of the present study was to characterize immuno-phenotypic features, proliferative capacity and immunogenicity of haecs. we also tested whether expression of some cell surface markers is influenced by the type of tryps...
introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...
هم کشتی سلول های بنیادی با یکدیگر دریچه های جدیدی را فرا روی محققین علم سلول درمانی گشوده است. با این روش میتوان سبب بهبود شرایط کشت و تمایز بهتر سلول های بنیادی شد. فاکتورهای رشد عصبی (neurotrophic factors,ntfs)، مولکول هایی هستند که نقش های بسیار حیاتی در بقا، تکثیر و تمایز سلول های بنیادی دارند. هدف از این تحقیق ارزیابی بیان فاکتورهای نوروتروفیک (gdnf، bdnf، cntf،nt3) و سرعت تکثی...
abstract background b cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. it has been shown that b cells produced successfully in the presence of stem cell factor (scf) and flt3 ligand (flt3l). il2, il7, and il15 cytokines as -common family have an essential cytokines may support either synergistically or in an additi...
چکیده سرطان پروستات، شایع ترین سرطان و دومین عامل مرگ ناشی از سرطان در مردان می باشد. بر اساس بسیاری از مطالعات، آنزیم 15-لیپوکسیژناز نوع 1 (15-lox-1) و متابولیت های آن در انواع سرطان ها از جمله سرطان پروستات دخیل اند. به صورتی که بیان این آنزیم در سرطان پروستات، با درجه بدخیمی ارتباط مستقیم دارد. بنابراین به نظر می رسد که مهار انتخابی 15-lox-1 در این سلول ها موجب القای آپوپتوز گردد. بدین منظو...
background: the use of stem cells is considered as an appropriate source in cell therapy and tissue engineering. differentiation of human induced pluripotent stem cells (hipscs) to hepatocyte-like cells (hlcs) on mouse embryonic fibroblasts (mefs) feeders is confronted with several problems that hinder the clinical applications of these differentiated cells for the treatment of liver injuries. ...
background: the definitive endoderm (de) differentiation using the undefined media and non-human feeders can cause contaminations in the generated cells for therapeutic applications. therefore, generating safer and more appropriate de cells is needed. this study compared five different methods to establish an appropriate method for inducing an efficient de differentiation from human induced plu...
