isolation, characterization and differentiation of rat adipose tissue derived mesenchymal stem cells
introduction: mesenchymal stem cells have the potential of self-renewal and differentiation into different cell types, including blood cells, heart, nerves and cartilage, and have unlimited power for division. these cells can be obtained from cord, before implantation from fertilized cells and also from various tissues of adults although the differentiation power and the ability to reproduce ...
background: central nervous system (cns) tumors have accounted for approximately one fourth of all pediatric malignancies. cns tumors have been the most common solid malignancies among the children. in this study, we have evaluated survival and prognostic factors in children with non-brain stem astrocytoma. methods: children with non-brain stem astrocytoma, referring to radiation oncology cente...
stem cells can be valuable model systems for drug discovery and modelling human diseases as well as to investigate cellular interactions and molecular events in the early stages of development. controlling the differentiation of stem cells into specific germ layers provides a potential source of highly specialized cells for therapeutic applications. in recent years, finding individual propertie...
Background: Stem cells represent an ideal cell source for application in tissue engineering and regenerative medicine due to their ability to proliferate and differentiate to a wide variety of cell lineages. With recent development of medical sciences and tissue engineering, usage of adipose-derived mesenchymal stem cells, their culture and differentiation on suitable scaffolds are considered a...
oct4 یکی از ژنهای مهم و کلیدی در سلولهای بنیادی است و کد کننده یک فاکتور رونویسی است که نقش کنترل بیان ژنهای مرتبط با بنیادی بودن (stemness) را به عهده دارد. با فرایند پیرایش افتراقیalternative splicing) ) حداقل سه واریانت مختلف با عملکرد متفاوت از این ژن سنتز میگردد. عمده ترین نقش این ژن کنترل پرتوانی (pluripotency) و خود باز آفرینی (self-renewal) در سلولهای بنیادی است، بطوریکه بیان این ژن نشا...
conclusions although the aforementioned challenges must still be addressed, the potential of wjmscs in skin regenerative clinical treatments is promising. results similar to bone marrow mscs, wjmscs express major histocompatibility complex (mhc) class i molecules. evidence acquisition according to research conducted by various researchers, wharton’s jelly mesenchymal stem cells (wjmscs) have se...
Introduction: Oxygen tension is one of the most important stimuli in stem cell biology. In this study, we investigate the considerable influence of hypoxia on CX43 gene expression as one of the most important gap junction on the surface of mesenchymal stem cells. Methods: Mesenchymal stem cells were isolated from C57BL/6 mouse bone marrow and cultured in DMEM medium under low oxygen tension (...
objective: the aim of this study was to estimate the cheminformatics and qualitative structure-activity relationship (qsar) of cinnamaldehyde and eugenol. the effects of cinnamaldehyde and eugenol on the viability, doubling time and adipogenic or osteogenic differentiations of human adipose-derived mesenchymal stem cells (hascs) were also investigated. materials and methods: qsar and toxicity ...
survival, proliferation, and migration of human meningioma stem-like cells in a nanopeptide scaffold
objective(s): in order to grow cells in a three-dimensional (3d) microenvironment, self-assembling peptides, such as puramatrix, have emerged with potential to mimic the extracellular matrix. the aim of the present study was to investigate the influence of the self-assembling peptide on the morphology, survival, proliferation rate, migration potential, and differentiation of human meningioma st...
objective: menstrual blood stromal stem cells (mbscs) share some phenotypic and functional similarities with mesenchymal stem cells (mscs). mscs are shown to inhibit either the function or generation of different immune cells, including dendritic cells (dcs). however, data regarding mbscs’ potential effects on immune system cells are elusive. here, we examine whether mbscs affect the generation...
