As reported by news.com.au, Australian scientists are in the early stages of exploring discarded baby teeth as a source of useful stem cells. The article is short on details regarding the type of stem cells used, but the researchers expect to be able to culture tissue from them. From the article: "Stem cells from teeth can be influenced to grow into tissue other than teeth. We have some evidence that some cells may have the potential to develop into neural cells. We now have a project injecting human cells into the brains of rats in the hope they can replace networks damaged by stroke or degenerative neural diseases."
