  • Method for culturing mesenchymal stem cell and method for producing biological tissue prosthesis
    Patent number: 7972767
    Abstract: The purpose is to proliferate a mesenchymal stem cell to a sufficient degree while reducing the amount of blood serum contained in a biological tissue progenitor cell to be grafted, and to efficiently differentiate the mesenchymal stem cell into the biological tissue progenitor cell. There is provided a method for culturing a mesenchymal stem cell, comprising: a first culture step of proliferating a mesenchymal stem cell in a medium containing blood serum; and a second culture step of differentiating the mesenchymal stem cell into a biological tissue progenitor cell in a medium containing blood serum at a lower concentration than that in the medium used in the first culture step.
    Type: Grant

  • CELL SEPARATION APPARATUS, METHOD FOR ACTIVATING FAT-DERIVED CELLS, GRAFT MATERIAL PRODUCING PROCESS, AND GRAFT MATERIAL
    Publication number: 20110111497
    Abstract: The therapeutic effect of a final product is improved while guaranteeing sterility. Provided is a cell separation apparatus comprising a decomposition treatment unit for producing a cell suspension by digesting living body tissue to release living body-derived cells from the living body tissue; a cell concentrating unit for generating a cell-concentrated solution by concentrating the cell suspension by centrifugation; and a efficiency-increasing mechanism for increasing the efficiency of the living body-derived cells contained in the cell-concentrated solution.
