  • Patent number: 8722404
    Abstract: Method for regeneration of mesenchymal tissue from mesenchymal cells on a porous sheet composed of bioabsorbable polymer material.
    Type: Grant
    Filed: February 22, 2010
    Date of Patent: May 13, 2014

  • Publication number: 20100158982
    Abstract: To provide a sheet for guiding regeneration of mesenchymal tissue having improved formability, strength, absorbability and efficiency, the sheet is produced by steps of containing a culture medium in a surface of a porous sheet produced by freezing a bioabsorbable polymer material dissolved with an organic solvent and drying it, seeding a mesenchymal cell grown after taking from biotissue, and differentiating the mesenchymal cell to a mesenchymal tissue precursor cell, where the mesenchymal tissue precursor cell and an extracellular substrate are adhered on the surface of the porous sheet containing a culture medium, and the extracellular substrate is secreted in a process of the mesenchymal cell being differentiated to the mesenchymal tissue precursor cell.
    Type: Application
    Filed: February 22, 2010
    Publication date: June 24, 2010
    Applicants: GC CORPORATION, TWO CELLS Co., Ltd.
