abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
Mesenchymal stem cells (MSCs) provide a novel option in cellular therapy and tissue engineering. Recent studies indicated that it is possible to obtain MSCs from peripheral blood by attachment ability to plastic surface. To evaluate adherent cells derived from peripheral blood, their expression profile and surface markers were investigated. The results of RT-PCR indicated that these cells expre...
Background & Objective : Bone marrow stromal cells (BMSCs) are a kind of stem cells with high pluripotency. The BMSCs can differentiate into mesodermal and non mesodermal cells. Because of availability of them, they are a suitable source of adult stem cells for cell therapy. Some inducers were used to differentiate stem cells into neural phenotype, such: retinoic acid, dimethyl sulfoxide, dep...
Numerous studies have shown the positive effects of rosmarinic acid on the nervous system. Rosmarinic acid as a herbal compound with anti-inflammatory effects can prevent the destructive effect of inflammation on the nervous system. Furthermore, various studies have emphasized the advantages of three dimensional (3D) culture over the two dimensional (2D) culture of cells. In this study, thermos...
Introduction: There are some evidences to suggest that bone marrow stromal cells (BMSCs) not only differentiate into mesodermal cells, but also adopt the fate of endodermal and ectodermal cell types. BMSCs can be a valuable cell source as an autograft for clinical application involving regeneration of the central nervous system. Bone marrow stromal cells can be expanded rapidly in vitro and can...
Introduction: The induction of human umbilical cord-derived mesenchymal stem cells (HUC-MSCs) toward dopaminergic neurons is a major challenge in tissue engineering and experimental and clinical treatments of various neurodegenerative diseases, including Parkinson disease. This study aims to differentiate HUC-MSCs into dopaminergic neuron-like cells. Methods: Following the isolation and charac...
background: mesenchymal stem cells (msc) are a very promising transplantable stem cell source for a variety of cell replacement therapies. as the main source of msc is bone marrow (bm), most of studies have been done on bm-derived msc (bm-msc). umbilical cord (uc)-derived msc (uc-msc) which are recently introduced, is one of the good alternative source for these cells. the objective of this stu...
Background and Objective: Biomaterials and nanomaterials have generated a great opportunity in regenerative medicine. Neurological disorders can result in permanent and severe derangement in motor and sensory functions. This study was conducted to examine the effects of selenium nanoparticles (Se NPs) as a chemical inducer for differentiation of PC12 cells into sympathetic-like neurons characte...
Circadian rhythm is a biological process that regulates neuronal, metabolic, and hormonal functions following 24-hour cycle. Parkinson’s disease (PD) progressive neurodegenerative disorder, it exhibits diurnal fluctuations in motor non-motor symptoms. Recently, increasing attention has been paid to circadian dysfunction PD patients. This review summarizes the existing research on rhythms especi...
