Background and Objective: The importance of β-adrenergic signals in bone formation and resorption has been well investigated. However, little is known about the role of β -adrenergic signals in osteoblastic differentiation of mesenchymal stem cells (MSCs), which is critically important in bone physiology and pharmacology. In this study, RUNX2 and Osteocalcin gene expression were quantified in M...
OBJECTIVE To characterize equine muscle tissue- and periosteal tissue-derived cells as mesenchymal stem cells (MSCs) and assess their proliferation capacity and osteogenic potential in comparison with bone marrow- and adipose tissue-derived MSCs. SAMPLE Tissues from 10 equine cadavers. PROCEDURES Cells were isolated from left semitendinosus muscle tissue, periosteal tissue from the distomed...
Abstract Background: Diabetes is a metabolic chronic disorder that makes it difficult to heal wounds because of its complications. To this point, many studies on the use of mesenchymal stem cells in wound healing process particularly diabetic ulcers have been done. In this study, we evaluate the impact of mesenchymal stem cells-derived conditioned medium (MSC-CM) on diabetic wound strength. Mat...
Previous studies have provided evidence for the existence of adult human bone marrow stromal stem cells (BMSSCs) or mesenchymal stem cells. Using a combination of cell separation techniques, we have isolated an almost homogeneous population of BMSSCs from adult human bone marrow. Lacking phenotypic characteristics of leukocytes and mature stromal elements, BMSSCs are non-cycling and constitutiv...
introduction: bone marrow contains a population of stem cells capable of differentiating to osteoblast and forming the bone nodule by dexamethasone. material and methods: the stromal cells of bone marrow obtained from 4 to 6 weeks old spruge-dawely male rats were grown in primary culture for 7 days and subcultured for 18 days. the cells were cultured in either dmem medium containing 15% fetal c...
Introduction: Oxygen tension is one of the most important stimuli in stem cell biology. In this study, we investigate the considerable influence of hypoxia on CX43 gene expression as one of the most important gap junction on the surface of mesenchymal stem cells. Methods: Mesenchymal stem cells were isolated from C57BL/6 mouse bone marrow and cultured in DMEM medium under low oxygen tension (...
Fanconi anemia is a complex heterogeneous genetic disorder with a high incidence of bone marrow failure, clonal evolution to acute myeloid leukemia and mesenchymal-derived congenital anomalies. Increasing evidence in Fanconi anemia and other genetic disorders points towards an interdependence of skeletal and hematopoietic development, yet the impact of the marrow microenvironment in the pathoge...
Introduction: Amniotic fluid contains a mixture of different cell types sloughed from the fetal skin, respiratory, alimentary and urogenital tracts, as well as the amnion membrane. As amniotic fluid develops prior to the process of gastrulation, many cells found in its heterogeneous population do not undergo lineage specialization. Therefore, amniotic fluid-derived mesenchymal stem cells (AF-MS...
Increase in endothelial cell sloughing and diminished function of endothelial stem cell progenitors in diabetic subjects are well known phenomena. We hypothesized that transplantation of bone marrow stem cells (BMSCs) including mesenchymal stem cells but not limited to CD34(+) stem cells into type 2 diabetic ob mice would restore insulin sensitivity and glucose tolerance. This approach, when co...
