  • Method for culture of cells
    Patent number: 11959100
    Abstract: As a technique for proliferating neural crest cells without reducing differentiation capacity, provided is a method for producing neural crest cells, comprising the steps of: (1) obtaining neural crest cells; and (2) suspension-culturing the neural crest cells in a medium comprising a GSK3? inhibitor and a basic fibroblast growth factor (bFGF), wherein the medium comprises the GSK3? inhibitor with a concentration that exhibits an effect equivalent to that exhibited by CHIR99021 with a concentration of higher than 1 ?M and lower than 5 ?M.
    Type: Grant
    Filed: November 29, 2018
    Date of Patent: April 16, 2024
    Assignees: Kyoto University, Takeda Pharmaceutical Company Limited
    Inventors: Makoto Ikeya, Yayoi Kamiya
  • METHOD FOR PRODUCING ENTERIC NEURAL PRECURSORS
    Publication number: 20210198624
    Abstract: A method for producing enteric neural precursors, comprising the steps of: (1) providing enteric neural precursors; and (2) culturing the enteric neural precursors in a medium comprising an ERBB3 agonist and/or an ERBB4 agonist is provided as a technique for allowing enteric neural precursors to proliferate by culture while maintaining their differentiation capacity into enteric nerve cells and glial cells.
