    摘要: Mesenchymal precursors cells have been isolated from perivascular niches from a range of tissues utilizing a perivascular marker. A new mesenchymal precursor cell phenotype is described characterized by the presence of the perivascular marker 3G5, and preferably also alpha smooth muscle actin together with early developmental markers such as MUC 18, VCAM-1 and STRO-1bri. The perivascular mesenchymal precursor cell is multipotential and is shown to form, vascular tissue, as well as bone marrow dentin and pulp. A method of enriching using cell sorting based on these markers is also described.

    摘要: A method of enriching mesenchymal precursor sells including the step of enriching for cells based on at least two markers. The markers may be either i) the presence of markers specific for mesenchymal precursor cells, ii) the absence of markers specific for differentiated mesenchymal cells, or iii) expression levels of markers specific for mesenchymal precursor cells. The method may include a first solid phase sorting step utilizing MACS recognizing expression of the antigen to the STRO-1 Mab, followed by a second sorting step utilizing two color FACS to screen for the presence of high level STRO-1 antigen expression as well as the expression of VCAM-1.
