abstract background: sodium arsenite (sa) recently has been recommended to be used in malignancy therapy. our studies showed, sa in short and long period of treatment caused reduction of rats bone marrow mesenchymal stem cells (mscs) viability and induced caspase dependent apoptosis. the aim of this study was to investigate the effect of sa on osteogenic differentiation of mscs. methods: mscs w...
Background: Adipose-derived stem cells (ADSC) could be an appealing alternative to bone marrow stem cells (BMSC) for engineering cell-based osteoinductive grafts. Meanwhile, prior studies have demonstrated that melatonin can stimulate osteogenic differentiation. Therefore, we assayed and compared the melatonin effect on osteogenic differentiation of BMSC with that of ADSC. Methods: Mesenchymal...
Objective(s): The aim of this study was to investigate the effect of curcumin on the osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) and its underlying potential mechanism.Materials and Methods: The tissue explant adherence method was used to isolate hPDLSCs. Flowcytometry, Alizarin Red staining and Oil Red ...
Introdution: Bisphenol A (BPA) disturbs the morphology, viability and differentiation of rat bone marrow mesenchymal stem cells (rMSCs) to osteoblast via the production of free radicals. Vitamin C (vit-C) is a potent antioxidant and protects cells against oxidative stress. The aim of this study was to investigate the effect of co-treatment of BPA and vitamin C as an antioxidant on the viability...
Introduction & Objective: In recent years stem cells have been evaluated for regenerating lost tissues. Therefore, many studies aimed to assess isolation of these cells from different origins, and culture them. The purpose of this study is to evaluate the osteogenic differentiation of stem cells derived from periodontal ligament of periodontitis affected teeth in melatonin contained media. M...
Background: The cultured mesenchymal stem cells (MSC) have been used in many clinical trials however, there are still some concerns about the cultural conditions. One concern is related to the use of FBS as a widely used xenogeneic supplement in the culture system. Human platelet-rich plasma (hPRP) is a candidate replacement for FBS. In this study, the effect of hPRP on MSC proliferation and os...

Background and Objectives : RUNX2 is the most specific transcription factor in osteoblastic differentiation of MSCs. In this research, RUNX2 expression was quantified in MSCs differentiated by osteogenic differentiation medium (ODM) and zoledronic acid (ZA). Materials and Methods: In this experimental study, hMSCs were treated by osteogenic differentiation medium and ZA. RNA extraction was ...
Transforming growth factor-β (TGF-β) is a critical regulator of osteogenic differentiation and the platelet-derived growth factor (PDGF) is a chemoattractant or mitogen of osteogenic mesenchymal cells. However, the combined effects of these regulators on the osteogenic differentiation of mesenchymal cells remains unknown. In this study, we investigated the effects of TGF-β and/or PDGF on the os...
Bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. Recently, various stem cells, including embryonic stem cells (ESCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs), adipose tissue-derived stem cells (ADSCs), muscle-derived stem cell...
