| Outline of Final Research Achievements |
We have established gastrointestinal cancer organoids from the patient. As a result, we succeeded in isolating 4 kinds of tumor organoids including colorectal, gastric , liver, and pancreatic cancer from patient. It was possible to continuously and long-term culture of each of the human gastrointestinal cancer organoids by optimizing the culture condition based on the orgnoid culture protocol. We also have been successful knocked-in reporter to LGR5 locus of intestinal organoids using genome editing. Each gastrointestinal cancer organoids derived from patients became culture in 384-well plate. Furthermore, we have established tumor organoids; based High-throughput drug screen system. Image analysis was performed with 360 drugs on tumor organoids using High Contents Analyzer. Our results suggest that our established HTS for tumor organids will be apply to genetic mutation based drug discovery and personalized medicine.
