Mapping tumor heterogeneity: ex-vivo drug responses in matched primary and metastatic tumors using a 3D functional precision platform
Introduction: Tumors are known to develop genomic heterogeneity over time, particularly in metastatic disease, raising concerns that a single-site biopsy may be insufficient to accurately predict response to medications. Methods: We used our 3D microtumor functional profiling platform that preserves key features of the...
