Bone-marrow stromal cells can differentiate into multiple mesenchymal lineages including cartilage and bone. When these cells are seeded in high-density 'pellet culture', they undergo chondrogenesis and form a tissue that is morphologically and biochemically defined as cartilage. Here, we show that dual chondro-osteogenic differentiation can be obtained in the same micromass culture of human bo...
Calcium binding properties of bone acidic glycoprotein-75, osteopontin, and bone sialoprotein were determined in 10 mM imidazole buffer (pH 6.8), containing either 60 mM KCl or 150 mM NaCl. Proteins assayed were first bound to nitrocellulose to mimic substrate-bound forms in vivo; retention of phosphoproteins was determined through use of radioiodinated tracers. Binding studies were carried out...
Tendons/ligaments insert into bone via a transitional structure, the enthesis, which is susceptible to injury and difficult to repair. Fibrocartilaginous entheses contain fibrocartilage in their transitional zone, part of which is mineralized. Mineral-associated proteins within this zone have not been adequately characterized. Members of the Small Integrin Binding Ligand N-linked Glycoprotein (...
BACKGROUND Calcific aortic stenosis is the third most common cardiovascular disease in the United States. We hypothesized that the mechanism for aortic valve calcification is similar to skeletal bone formation and that this process is mediated by an osteoblast-like phenotype. METHODS AND RESULTS To test this hypothesis, we examined calcified human aortic valves replaced at surgery (n=22) and ...
