  • Method for induction/differentiation into photoreceptor cell
    Patent number: 9133435
    Abstract: The present invention provides a method of producing primate retinal progenitor cells, comprising culturing primate embryonic stem cells as suspended aggregates in a serum-free medium, and obtaining retinal progenitor cells from the culture. The present invention further provides a method of producing photoreceptor precursor cells, comprising culturing isolated retinal progenitor cells differentiated from embryonic stem cells, under adhesive conditions, in the presence of a gamma secretase inhibitor, and obtaining a photoreceptor precursor from the culture.
    Type: Grant
    Filed: January 11, 2008
    Date of Patent: September 15, 2015
    Assignee: RIKEN
    Inventors: Masayo Takahashi, Fumitaka Osakada, Michiko Mandai, Hanako Ikeda
