| Outline of Final Research Achievements |
We have created recombinant animal model systems in which radiation- or environmental mutagen-induced mutations at somatic and germ cells are readily detected in vivo and in situ living tissues without destroying tissue three-dimensional structure. The new animal system has a marked contrast with conventional mutant detecting system which requires cell/tissue lysis and DNA extraction. Our model animals will enable the observation of mutant stem cell propagations in the organisms (cell lineage tagging) and provide the new measure of risk assessment for environmentalmutagens. The HPRTdupGFP mouse is now donated in mutant mice repository for the use of basic research. Patent for commercial use is also granted.
