  • Patent number: 11512284
    Abstract: There is provided a method of inducing differentiation of bone marrow stromal cells to neural cells or skeletal muscle cells by introduction of a Notch gene. Specifically, the invention provides a method of inducing differentiation of bone marrow stromal cells to neural cells or skeletal muscle cells in vitro, which method comprises introducing a Notch gene and/or a Notch signaling related gene into the cells, wherein the finally obtained differentiated cells are the result of cell division of the bone marrow stromal cells into which the Notch gene and/or Notch signaling related gene have been introduced. The invention also provides a method of inducing further differentiation of the differentiation-induced neural cells to dopaminergic neurons or acetylcholinergic neurons. The invention yet further provides a treatment method for neurodegenerative and skeletal muscle degenerative diseases which employs neural precursor cells, neural cells or skeletal muscle cells produced by the method of the invention.

  • 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.
