objective: pulp and periodontal tissues are well-known sources of mesenchymal stem cells (mscs) that provide a promising place in tissue engineering and regenerative medicine. the molecular mechanisms underlying commitment and differentiation of dental stem cells that originate from different dental tissues are not fully understood. in this study, we have compared the expression levels of pluri...

multipotent mesenchymal stromal cells or mesenchymal stem cells (mscs) are mainly isolated from bone marrow or fat tissue. because of their potential of multilineage differentiation towards bone, cartilage and fat tissue, they were initially evaluated to develop innovative strategies for tissue engineering applications. more recently, they have gained interest based on their immunomodulatory pr...

Background  The mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. Stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. This source of stem cells avoids invasive procedures and the ethical controversy of emb...

Background: Periodontal ligament stem cells (PDLSCs) are considered as a type of mesenchymal stem cell that is beneficial target for numerous clinical applications in periodontal tissue regeneration therapy. Materials and Methods: This study examined the effects of dexamethasone (Dex) on human PDLSCs in vitro. PDLSCs obtained from the roots of patient’s teeth were cultured with Dex (0....

background: mesenchymal stem cells (msc) have ability to regulate immune response via proinflamatory cytokines. in this study we aimed to investigate the effect of different mechanism for t cell activation and adjacency on immunoregulatory properties of msc. methods: bone marrow mscs were purchased and t cells were obtained from whole blood sample. t cells were activated by two different mechan...

objective(s): stem cell therapy is believed to be as a promising treatment strategy for tissue repair and regeneration. the plasticity specification of the adult stem cells, such as mscs, has enabled that these cells to be used in the treatment of a broad spectrum of diseases like liver disorders. in this study, the production of urea and albumin (alb), glycogen storage, and expression of some ...

objective(s): the main characteristic of mesenchymal stem cells (mscs) is their ability to produce other cell types. electromagnetic field (emf) stimulates differentiation of mscs into other cells. in this study, we investigated whether emf can effect on the differentiation of mscs into dopaminergic (da) neurons. materials and methods: an emf with a frequency of 50 hz and two intensities of 40 ...

introduction: in this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. methods: bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μm of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan blue ...

human umbilical cord matrix (hucm) is considered as a promising source of mesenchymal stem cells (mscs) due to several advantages over other tissues. the potential of neural differentiation of hucm-mscs is of great interest in the context of treating neurodegenerative diseases. in recent years, considerable efforts have been made to establish in vitro conditions for improving the differentiatio...
