Scientists grow fully functional tooth from stem cells

Though teeth have been grown in mice before, scientists revealed in the Proceedings of the National Academy of Sciences their success at growing a “fully functional” tooth from stem cells in mice.

The article states:

“Here, we report a successful fully functioning tooth replacement in an adult mouse achieved through the transplantation of bioengineered tooth germ into the alveolar bone in the lost tooth region. We propose this technology as a model for future organ replacement therapies. The bioengineered tooth, which was erupted and occluded, had the correct tooth structure, hardness of mineralized tissues for mastication, and response to noxious stimulations such as mechanical stress and pain in cooperation with other oral and maxillofacial tissues. This study represents a substantial advance and emphasizes the potential for bioengineered organ replacement in future regenerative therapies.”

The process is described in a paper titled “The development of a bioengineered organ germ method” in the journal Nature Methods by researchers with the Department of Biological Science and Technology at the Tokyo University of Science.
