  • Publication number: 20230213501
    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.

  • Publication number: 20220243175
    Abstract: The present invention relates to a method for isolating and culturing neural stem cells with high efficiency, which may shorten the time for isolation and culture by simplifying a method for isolating and culturing neural stem cells and may increase the acquisition yield of neural stem cells. The present invention provides a method for isolating and culturing neural stem cells with high efficiency, comprising the steps of adding brain tissue into an enzyme solution so as to subject the brain tissue to enzyme treatment; physically isolating cell clumps from the enzyme treated brain tissue by dividing the cell clumps according to size and removing impurities; and inoculating the cell clumps on a culture dish so as to subculture.

  • Publication number: 20210009950
    Abstract: The present invention relates to an angiogenesis-inducing method using neural stem cells. According to the present invention, neural stem cells derived from human brain tissues release MCP-1 or Gro, thus exhibiting an angiogenesis-inducing effect. When CoCl2 was treated to the neural stem cells of the present invention and when the neural stem cells were cultured in a hypoxia chamber, it was observed that a hypoxia condition increased the release amounts of MCP-1 and Gro. Therefore, the human brain tissue-derived neural stem cells of the present invention can be used to induce angiogenesis.

  • Patent number: 9750826
    Abstract: Provided is a method for producing a glioblastoma mouse model and the mouse model produced thereby, the method including the steps of: (a) dividing a glioblastoma tissue, isolated from a patient, into 4 or more sections, and collecting one or more pieces from each of the sections; (b) dissociating a mixture of the collected pieces into glioblastoma cells as single cells; and (c) orthotopically transplanting a graft sample containing the glioblastoma cells obtained in step (b), into the brain of an immunodeficient mouse. Further provided are a method of screening a glioblastoma therapeutic agent using the mouse model and a method of providing information for selection of a patient-specific glioblastoma therapy using the mouse model. The glioblastoma mouse model shows the same genetic, morphological and pathological characteristics as those of the parental tumor, and it allows screening patient-specific glioblastoma therapeutic agent or selecting safer and more effective patient-specific glioblastoma therapy.

  • 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.

  • 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.
