Australian researchers are trying to determine whether stem cells from teeth could one day be used to help repair brain damage.
Previous research has suggested that these stem cells are able to create new brain tissue - now a team is investigating whether there is potential to help stroke victims.
The Centre for Stem Cell Research at the University of Adelaide has recruited a team of around 100 scientists and 80 students to work on treatments for a number of diseases, AdelaideNow.com reports.
Rats will be the subjects of initial studies for the first five years, to be followed by humans if positive results are noted.
Project coordinator Dr Simon Koblar told Australia's ABC News that the stem cells come from young people with impacted wisdom teeth.
"We remove the tooth and you can break it open and inside the tooth are some stem cells, so you can grow them in a test tube," he explained.
In August, Japanese researchers announced that they could produce stem cells from teeth that had been preserved for as long as three years.
