Patient-derived organoids (PDOs) have emerged as a promising model for personalized drug testing. Generated from human tumor samples, PDOs effectively recapitulate the genetic and phenotypic heterogeneity of patient tumors, making them an ideal ex vivo platform for studying therapeutic responses, particularly to chemotherapies. However, their lack of components of the immune system limits their use in immunotherapy testing. The following protocol facilitates the co-culture of PDOs from tumor tissue with HLA-matched peripheral blood mononuclear cells (PBMCs) in a fixed Z-plane for stable live-cell imaging. This three-dimensional co-culture method represents a significant advancement in enabling real-time assessment of immunotherapeutic effects on tumor-derived PDOs by live cell imaging.

摘要

Patient-derived organoids (PDOs) have emerged as a promising model for personalized drug testing. Generated from human tumor samples, PDOs effectively recapitulate the genetic and phenotypic heterogeneity of patient tumors, making them an ideal ex vivo platform for studying therapeutic responses, particularly to chemotherapies. However, their lack of components of the immune system limits their use in immunotherapy testing. The following protocol facilitates the co-culture of PDOs from tumor tissue with HLA-matched peripheral blood mononuclear cells (PBMCs) in a fixed Z-plane for stable live-cell imaging. This three-dimensional co-culture method represents a significant advancement in enabling real-time assessment of immunotherapeutic effects on tumor-derived PDOs by live cell imaging.
