The primary question is whether the patient's response to temozolomide is recapitulated in their corresponding patient-derived glioblastoma organoid (GBO). Patient drug responses are evaluated using survival data, while GBO drug responses are assessed through a drug-response testing platform utilizing cell viability assays. Additionally, this platform is used to explore the potential application of various chemotherapeutic agents.",[70,71],"Glioblastoma","Organoid",[73,9,74,75],"organoid","GBO","drug-screening","2025-01-14",{"date":78,"type":79},"2025-01-20","ACTUAL",{"date":81,"type":79},"2021-08-18",{"date":83,"type":65},"2030-12",{"name":5,"class":6},1]
