  • Patent number: 9493739
    Abstract: The present invention relates to stem cells in which a gene that activates signaling is introduced and to a method for proliferating the stem cells. More specifically, the invention relates to a method of significantly increasing the ability of stem cells to proliferate, either by transfecting stem cells with the Notch intracellular domain (NICD) to activate the Notch signaling pathway, or by transfecting stem cells with the c-MET gene and treating the transfected stem cells with the HGF ligand protein to activate the c-MET/HGF signaling pathway. According to the present invention, as a result of activating the Notch signaling pathway or the c-MET/HGF signaling pathway, stem cells having an excellent ability to proliferate can be produced in large amounts. Particularly, since neural stem cells which have been difficult to culture in vitro can be proliferated in large amounts, thus the neural stem cells will be more useful for the preparation of cell therapeutic agents for treating cranial nerve diseases.

  • Publication number: 20160103119
    Abstract: The present invention relates to a system for screening personalized anticancer agents, a method for screening personalized anticancer agents using the system, and an apparatus for screening personalized anticancer agents. When the inventive system for screening personalized anticancer agents is used, an anticancer agent showing an optimal anticancer activity against cancer cells collected from a patient can be selected from a variety of anticancer agents, and it is possible to previously examine a therapeutic response that can appear when the selected anticancer agent is administered into the patient. Thus, the risk of trial and error in cancer therapy can be reduced, and the cost and time required for cancer therapy can be reduced.

  • Patent number: 9296817
    Abstract: The antibody of the invention has high specificity to human c-Met and is cross-reactive to mouse c-Met. The antibody or its antigen-binding fragment of the invention is capable of specifically binding to human c-Met as well as mouse c-Met, more accurate preclinical results can be confirmed in the efficacy evaluation using mouse tumor models. The antibody of the invention inhibits the growth of cancer cells derived from various cancers by a considerable binding affinity to c-Met and the suppression of c-Met function therefrom, inhibits the phosphorylation of c-Met and downstream signaling molecules to suppress c-Met signaling, and inhibits neovascularization, thereby being very efficient in the prevention and treatment of cancers.
