Scientists in Japan have managed to grow fully functional teeth in mice using stem cells, and are hopeful the same technique can be used to grow human organs in the future.

The researchers created a seed containing cells from a mouse embryo, and later planted it into the jawbones of adult mice. The teeth then grew into place, complete with nerve fibres and enamel.

Scientists have previously been able to grow tissue in laboratories and transplant it into live animals, but this is the first time that the tissue was allowed to grow in the animal. The japanese team now harbour hopes that this technique can be used to grow human organs.
