MT1-MMP is a membrane-bound matrix metalloproteinase (MT-MMP) capable of mediating pericellular proteolysis of extracellular matrix components. MT1-MMP is therefore thought to be an important molecular tool for cellular remodeling of the surrounding matrix. To establish the biological role of this membrane proteinase we generated MT1-MMP-deficient mice by(More)
We report the isolation of adherent, clonogenic, fibroblast-like cells with osteogenic and adipogenic potential from the blood of four mammalian species. These cells phenotypically resemble but are distinguishable from skeletal stem cells found in bone marrow (stromal stem cells, "mesenchymal stem cells"). The osteogenic potential of the blood-borne cells(More)
Limited-sized transplants of culture-expanded autologous or allogeneic bone marrow stromal cells (BMSCs) form cortico-cancellous bone in rodent models. Initiation of clinical studies using autologous BMSC transplantation requires effective bone formation among sizable transplants in a large animal model as well as noninvasive techniques for evaluating(More)
We report the isolation of adherent, clono-genic, fibroblast-like cells with osteogenic and adipogenic potential from the blood of four mammalian species. These cells phenotypically resemble but are distinguish-able from skeletal stem cells found in bone marrow (stromal stem cells, " mesenchymal stem cells "). The os-teogenic potential of the blood-borne(More)
