A team of researchers has succeeded in engineering stem cells taken from tooth germ to quickly develop into liver or bone tissue, the National Institute of Advanced Industrial Science and Technology's Research Institute (AIST) for Cell Engineering said. A joint team of scientists from the institute and Osaka University succeeded in repairing damaged liver and bones in rats using stem cells taken from wisdom tooth germ. The finding raises hopes of developing regenerative medicine using wisdom teeth germ taken from people during orthodontic treatments. Tooth germ disappears as a tooth is formed, but that of a wisdom tooth stays in...
