  • Patent number: 11512285
    Abstract: The present invention relates to a method of preparing induced neural stem cells which are reprogrammed from differentiated cells. The method of producing the induced neural stem cells according to the present invention enables preparation of the induced neural stem cells from non-neuronal cells using only two inducing factors of SOX2 and HMGA2. Therefore, the method of the present invention can prepare induced neural stem cells in a more efficient manner than the conventional methods, which use four or five inducing factors. Additionally, the method of the present invention shows significantly higher inducing efficiency and proliferation capacity than when only a single SOX2 gene is used, thus increasing its potency to be used for therapeutic purposes.
