  • Patent number: 10421946
    Abstract: 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.

  • Publication number: 20190167846
    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.
