  • Publication number: 20110183350
    Abstract: In order to provide a therapeutic agent for nerve injury which contains iPS-derived neural stem cells and has low or no risk of side effects, as well as a method for treating a nerve injury using the iPS cells, by efficiently establishing in vivo the iPS-derived neural stem having low or no risk of tumor formation, neurospheres are formed following formation of embryoid bodies from the iPS cells, and a clone whose ratio of cells in which the promoter of Nanog gene is activated is 0.01% or less is selected, and the clone is administered to a patient suffering from the nerve injury.

  • Publication number: 20090208465
    Abstract: The present invention provides a therapeutic agent for a nerve injury and a method for treating a nerve injury. One aspect of the invention is the method for treating a nerve injury by administering to a patient with a nerve injury a therapeutic agent for a nerve injury containing a differentiated cell-derived pluripotent cell obtained by forced expression of reprogramming genes such as a combination of the Oct3/4 gene, Sox2 gene, Klf4, and c-myc gene. in a differentiated cell; or cells obtained by inducing the aforementioned differentiated cell-derived pluripotent cells to differentiate into an embryoid body or a neurosphere.
