  • Patent number: 10973884
    Abstract: The present invention relates to a pharmaceutical composition for treating cancer, containing cytochrome b5 reductase 3 (CYB5R3) protein as an active ingredient. Over-expression of CYB5R3 in cancer cells results in significant reduction of hypoxia-inducible factor-1? (HIF-1?) expression, which leads inhibition of cancer cells growth in vitro and in vivo. Thus, the CYB5R3 gene or protein of the present invention can be useful as an active ingredient of a pharmaceutical composition for treating cancer.

  • Patent number: 10760051
    Abstract: The present invention relates to a method for producing astrocytes comprising obtaining neural progenitor cells from stem cells so as to continuously produce astrocytes with high purity and same traits, followed by two steps of differentiating the neural progenitor cells into the astrocytes, and astrocytes produced therefrom. Since the method of preparing the astrocytes provided in the present invention enables not only production of the astrocytes with high purity and faster production of the astrocytes with same characteristics, but also rapid differentiation of the astrocytes using the neural progenitor cells when necessary, it can be widely used for effectively treating a patient with a disease which requires transplantation of the astrocytes.

  • Patent number: 10231999
    Abstract: The present invention relates to a method for producing cholinergic neurons comprising obtaining neural progenitor cells from stem cells so as to continuously produce cholinergic neural cells with high purity and the same traits, followed by differentiating the neural progenitor cells into the cholinergic neurons, and cholinergic neurons produced therefrom. Since the method of preparing the cholinergic neurons provided in the present invention enables not only production of the cholinergic neurons with high purity, but also rapid production of the cholinergic neurons with the same traits, it can be widely used for effectively treating degenerative cranial nerve diseases such as Alzheimer's disease.
