| Outline of Final Research Achievements |
A new X-ray imaging probe 2Ke2-TIB has been created in addition to Ke4-TIB. These probes were examined for in vivo imaging of articular cartilage by CT using rat osteoarthritic model. A new patent regarding Ke4-TIB has been established on March 24th, 2017. Since we speculate the increasing use of mouse genetic model for drug discovery research, we created a new mouse genetic model by crossing floxed "A" gene mice, encoding a proteoglycan gene abundant in the articular cartilage, with Rosa26-creERT mice. The mice exhibited a dwarfism and articular cartilage degeneration after starting injection of tamoxifen at one week of age. These developments of new imaging probes and a mouse model will contribute to the future research on osteoarthritis drug discovery. A collaboration with a group in the University of Munich has started for nano Xray CT.
