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.
