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.

Method of preparing induced neural stem cells reprogrammed from non-neuronal cells using HMGA2

The present invention relates to a method for obtaining adult stem cells, which have a surface antigen of CD49f, excellent formation of spheres due to sphere formation and high expression of OCT4 and SOX2, from a cell source including stem cells, and a cell therapeutic agent containing adult stem cells obtained by the method or cells differentiated therefrom as an active ingredient. According to the present invention, adult stem cells derived from spheres are suitable for mass culture of adult stem cells because of more rapid growth thereof compared with stem cells obtained by a known adhesive culture method, have a specific surface antigen so as to be homogeneously obtained by using the specific surface antigen, and are useful for preparing a cell therapeutic agent using the same because of excellent differentiation thereof.
