bone is formed through the processes of endochondral and intramembranous ossification. in endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (mscs) differentiate directly into osteoblasts to form bone. the steps of osteogenic proliferation, differentiation,...

background: human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue. objective: the aim was to isolate human dental pulp stem cells (dpsc), periodontal ligament stem cells (pdlsc) and periapical follicle stem cells (pafsc) for their potential role in tissue regeneration. materials and methods: in this experimental s...

objective: evaluating the effects of p-benzoquinone and hydroquinone on the runx2 expression and osteoblastic differentiation of human marrow derived mesenchymal stem cells (mscs). materials and methods: bone marrow mscs obtained by cultivating marrow mononuclear cells, were exposed to 10μm of either p-benzoquinone or hydroquinone. following chemical treatment, runx2 gene expression was assess...

background: stem cell therapy in small animal medicineis still in its infancy and few in vitro and in vivo research projectsregarding animal mesenchymal stem cells (mscs) have beencarried out. on the other hand, cell tracking is the first step of thecell-based therapies and is essential to recognize cell fate posttransplantation. objectives: the aim of this study was toisolate, characterize, an...

objective: tooth loss is a common problem and since current tooth replacement methods cannot counter balance with biological tooth structures, regenerating natural tooth structures has become an ideal goal. a challenging problem in tooth regeneration is to find a proper clinically feasible cell to seed.this study was designed to investigate the odontogenic potential of human bone marrow mesench...

introduction: mechanical stimulation of human mesenchymal stem cells has demonstrated changes in many cell behaviours such as adhesion, migration, growth and differentiation through mechanotransductive pathways. these include experiments on effect of nanotopography 1, shear stress, stiffness of extracellular matrix 2, strain, stress and acoustic wave energy 3 on cells. in this research we were ...

Background: Dental Pulp Stem Cells (DPSCs) are multipotent mesenchymal stem cells. DPSCs can renew themselves and differentiate into various cell types such as adipocytes, osteocytes, neurons, etc. DPSCs possess immunomodulatory properties and can inhibit peripheral blood mononuclear cell (PBMC) proliferation. Recent studies showed that conditioned-medium mesenchymal stem cells also had immunos...

Objective(s) Mesenchymal stem cells (MSCs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. Human mesenchymal stem cells (hMSCs) are ideal targets in cell transplantation and tissue engineering. Enhanced green fluorescent protein (EGFP) has been an important reporter gene for gene therapy. The aim of this stu...
