  • Method for producing neurospheres
    Patent number: 9399759
    Abstract: In order to provide a method for producing neural stem cells easily and quickly by inducing differentiation of somatic cells directly into neurospheres, dedifferentiation factors are introduced into somatic cells, which are then cultured in suspension in the presence of growth factors to produce the neurospheres, thereby allowing the neural stem cells to be produced quickly without establishing iPS cells.
    Type: Grant
    Filed: November 4, 2009
    Date of Patent: July 26, 2016
    Assignee: Keio University
    Inventors: Wado Akamatsu, Hideyuki Okano

  • THERAPEUTIC AGENT FOR TUMOR OF NEURAL ORIGIN
    Publication number: 20070299031
    Abstract: The present invention is directed to a therapeutic agent for a tumor of neural origin, containing, as an active ingredient, any of the following: Hu protein; a polypeptide having an amino acid sequence derived from an amino acid sequence of Hu protein by substitution, deletion, addition, or insertion of one or more amino acid residues; or a gene encoding the amino acid sequence of Hu protein or the peptide. Thus, the present invention provides a novel method for treating neuroblastoma.
