Stem Cells From Wisdom Teeth

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

(From the Daily Yomiuri Online). Research teams around the world are working towards regenerative therapies using an ever-wider range of stem cell sources: "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. ... Tooth germ disappears as a tooth is formed, but that of a wisdom tooth stays in the jawbone of a human until the age of 10 to 16, because wisdom teeth grow slowly. An experiment proved that stem cells taken from wisdom tooth germ grow far more quickly than stem cells taken from bone marrow. The team discovered that the tooth germ can be turned into bone, nerves or liver cells by stimulating it with hormones."
