BACKGROUND/AIMS Bone marrow adipogenesis is one of the major characteristics of aged bone. Bone marrow mesenchymal stem cells (BMMSCs) prefer to differentiate into adipocytes instead of osteoblasts in the bone marrow cavity in aged hosts. The mechanism of formation and function of adipocytes in aged bone marrow needs further investigation. Osteoprotegerin (OPG) is a member of the tumor necrosis...
in the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. bone marrow mesenchymal stem cells (bm-mscs) possess all of these characteristics. one of the most important benefi...
Background and Aim: Different regulation processes have an effect on osteoblastic differentiation of mesenchymal stem cells (MSCs), and among them Wnt signaling pathway is particularly desirable. In Wnt signaling pathway, Adenomatous Polyposis Coli (APC) bind to β-catenin and induce its degradation, thereby acting as a negative regulator of canonical Wnt pathway. In this study, gene expression ...
background: the use of stem cells is considered as an appropriate source in cell therapy and tissue engineering. differentiation of human induced pluripotent stem cells (hipscs) to hepatocyte-like cells (hlcs) on mouse embryonic fibroblasts (mefs) feeders is confronted with several problems that hinder the clinical applications of these differentiated cells for the treatment of liver injuries. ...
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:more similarity to in vivo medium may help to increase the proliferation and differentiation of cells at in vitro condition. the present study has investigated the effect of a dynamic mediumand nano hydroxyapatite (nha) presence on proliferation and differentiation of mesenchymal stem cells (mscs) to bone cells using electrospun polycaprolactone (pcl) scaffolds. methods: we prepared p...
JMJD3 (KDM6B) is an H3K27me3 demethylases and emerges as an important player in developmental processes. Although some evidence indicated the involvement of JMJD3 in osteoblast differentiation in vitro, its role as a whole in osteoblast differentiation and bone formation in vivo remains unknown. Here we showed that homozygous deletion of Jmjd3 resulted in severe delay of osteoblast differentiat...
Diabetes osteoporosis is a common secondary bone Metabolic disorder, which seriously affects the quality of life patients. Traditional Chinese medicine categorizes it as "diabetes" combined with "bone dysfunction". Through consulting related literature diabetes induced osteoporosis, this paper summarized TCM understanding disease, etiology and pathogenesis, syndrome differentiation treatment, c...
Objective(s): The present study was aimed to evaluate the time-mannered and dose-dependent effects of 5α-dihydrotestosterone (5α-DHT) on the proliferation and differentiation of bone forming cells using MC3T3-E1 cells. Materials and Methods: Cell proliferation was analyzed using MTS and phase contrast microscopic assays. Osteogenic differentiation was assessed through a series of in vitro exper...
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...
