Abstract: [Problem] The present invention addresses the problem of providing a method for efficiently preparing dental pulp stem cells from dental pulp cells collected from dental pulp tissue. [Solution Means] The method for preparing dental pulp stem cells from dental pulp cells collected from dental pulp tissue according to the present invention includes: (a) a step for preculturing dental pulp cells using a culture medium that includes serum at 7-13% (v/v), the dental pulp cells being bonded to a culture dish; (b) a step for culturing the dental pulp cells bonded to the culture dish by step (a) at least for one day using a culture medium that includes serum at 7-13% (v/v); and (c) a step for culturing the dental pulp cells in a low-serum condition after step (b).

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.

Abstract: This invention discloses a stem cell modified animal model useful as a research tool for investigating aging-related degeneration processes and treatments. The animal model is preferably a rodent subcutaneously transplanted with a mesenchymal stem cell capable of generating a functional bone or marrow element. Also provided are a method for extending the lifespan and improving the quality of life of a subject by subcutaneously transplanting a plurality of mesenchymal stem cells to the subject, wherein the mesenchymal stem cells are capable of generating a functional bone or marrow element. Compositions and source of stem cells suitable for use with the methods of this invention, including stem cells from human exfoliated deciduous teeth (SHED), are also disclosed. Further disclosed is a method for identifying progenitor bone marrow mesenchymal stem cells, and a method for treating SLE-like autoimmune diseases by infusion of mesenchymal stem cells.
