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 ...
background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...
objective(s): electrospun nanofibrous mats of poly(lactic acid) (pla) and nanohydroxyapatite (nano-ha) were prepared and proliferation and differentiation of mesenchymal stem cells on the prepared nanofibers were investigated in this study. materials and methods: pla/nano-ha nanofibers were prepared by electrospinning. the effects of process parameters, such as nano-ha concentration, distance, ...
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...
Background and Objective: Mesenchymal stem cells are promising sources of stem cells for tissue repair because of their ability to differentiate into different cells, easy proliferation and culture, and immunomodulatory properties. Despite extensive research on the immunophenotype of mesenchymal stem cells, a lack of specific markers comprises challenges for researchers. The aim of this researc...
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: recent publications about differentiation of stem cells to germ cells have motivated researchers to make new approaches to infertility. in vitro production of germ cells improves understanding differentiation process of male and female germ cells. due to the problem of using embryonic stem cells (esc), it’s necessary the mentioned cells be replaced with some adult multi-potent stem ...
