  • Method for producing induced pluripotent stem cells
    Patent number: 9890360
    Abstract: A method that includes bringing a nuclear reprogramming substance (DLX4 gene, OCT3/4 gene, and SOX2 gene) into contact with a cell and thereby producing iPS cells.
    Type: Grant
    Filed: August 28, 2014
    Date of Patent: February 13, 2018
    Assignees: GIFU UNIVERSITY, NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY
    Inventors: Kenichi Tezuka, Naritaka Tamaoki, Kazuki Iida, Tomoko Kawaguchi, Hitomi Aoki, Takahiro Kunisada, Toshiyuki Shibata, Naoki Goshima
  • METHOD FOR PRODUCING GRAFT MATERIAL FOR TREATING NERVE DAMAGE
    Publication number: 20160296669
    Abstract: An object of the present invention is to provide a method for efficiently and reproducibly producing a graft material having a high recovery effect on dysfunction caused by nerve damage. The present invention provides a method for producing a graft material for treating nerve damage, including a step of culturing a dental pulp stem cell in a medium substantially containing no growth factors except FGF2, and others.

  • METHOD FOR PRODUCING INDUCED PLURIPOTENT STEM CELLS
    Publication number: 20160208218

  • EFFICIENT METHOD FOR ESTABLISHING INDUCED PLURIPOTENT STEM CELLS
    Publication number: 20110201110
    Abstract: The present invention provides a method of producing induced pluripotent stem (iPS) cells, comprising bringing a nuclear reprogramming substance into contact with dental pulp stem cells. By using dental pulp stem cells as a source of somatic cells, the efficiency of establishment of human iPS cells by transfer of 3 or 4 factors can be improved dramatically. Additionally, dental pulp stem cells are easily available because they can be isolated and prepared from extracted wisdom teeth and teeth extracted because of periodontal disease and the like, so that they can be used widely as a source of somatic cells for iPS cell banks.

  • Method for culturing neural stem cells using hepatocyte growth factor
    Publication number: 20060134078
    Abstract: A medium containing hepatocyte growth factor (HGF) was shown to induce neurosphere formation. Furthermore, the addition of HGF to a culture medium containing FGF-2, EGF, or both increased both the size and number of newly formed neurospheres. Thus, the present invention relates to a growth medium comprising HGF for culturing neural stem cells and methods for culturing the cells using the culture medium.
