From "Simulation" to "Mirror": Gene editing and humanization redefines the next-generation precision oncology animal model.

Abstract excerpt

Patient-derived xenograft (PDX) models, although conventionally used in oncology, exhibit critical limitations: they frequently lose patient-specific genetic mutations and lack the human leukocyte antigen (HLA) diversity essential for immune recognition, and fail to recapitulate the human tumor microenvironment (TME). These deficiencies contribute to immunotherapy prediction failure rates exceeding 80% in...
