  • METHOD FOR PRODUCING PLURIPOTENT STEM CELLS
    Publication number: 20240247236
    Abstract: The death of some pluripotent stem cells in suspension culture of pluripotent stem cells is avoided. When performing the suspension culture of the pluripotent stem cells, a liquid medium that does not substantially contain a PKC? inhibitor is used for a single-cell state and a liquid medium containing a PKC? inhibitor and a WNT inhibitor is used after a cell mass is formed.
    Type: Application

    Applicants: KANEKA CORPORATION, RIKEN
    Inventors: Sho KAMBAYASHI, Yoshikazu KAWAI, Yohei HAYASHI, Mami TAKASAKI
  • METHOD FOR PRODUCING PLURIPOTENT STEM CELL POPULATION
    Publication number: 20240035000
    Abstract: This invention is intended to suppress cell death occurring at the time of transition of adherent culture of pluripotent stem cells to suspension culture thereof. Pluripotent stem cells are subjected to adherent culture in a liquid medium comprising a PKC? inhibitor and a TNKS inhibitor and then to suspension culture.

  • METHOD FOR SUPPRESSING DIFFERENTIATION OF PLURIPOTENT STEM CELLS
    Publication number: 20230094568
    Abstract: Pluripotent stem cells are suspension-cultured with the undifferentiated state thereof maintained. In suspension culture of pluripotent stem cells, the undifferentiated state is maintained by the presence of a PKC inhibitor, especially, a PKC? inhibitor, and a tankyrase inhibitor (TNKS inhibitor).
