  • Publication number: 20100196854
    Abstract: A method for reconstructing a functional tooth by using a carrier loaded with a plurality of mesenchymal stem cells including at least one of a stem cell derived from Apical Papilla (SCAP), Periodontal Ligament Stem Cells (PDLSC), and Dental Pulp Stem Cells (DPSC). The mesenchymal stem cell loaded carrier is planted into a site within a subject's oral cavity to form a bio-root upon which a crown may be affixed, The mesenchymal stem cells will develop new periodontal tissues to stabilize the bio-root. Methods disclosed herein are particularly beneficial for subjects lacking good bone structures for conventional crown treatments.

  • Patent number: 7732126
    Abstract: The present invention is directed to a new bone marrow stromal stem cell (BMSSC) marker, CD18, for use in selecting a population of cells enriched in BMSSCs, from bone marrow cells, adipose cells, or peripheral blood. The invention is further directed to methods for selecting a population of cells enriched in BMSSCs based on the selective expression of CD18 on their surface, using techniques known in the art such as fluorescent assisted cell sorting, an immunomagnetic method, flow microfluorimetry, immunofluorescence, immunoperoxidase staining, radioimmunoassay and immunoaffinity chromatography. The invention is further directed to the BMSSCs isolated based on CD18 expression, and their use to treat various diseases. In one aspect, the HMSSCs are transformed with a vector having a normal gene for CD18, and the transformed BMSSCs are administered to treat bone degenerative diseases and diseases of bone involving abnormal expression of CD18 expression of CD18.
