Japanese Scientists "Regrow" Teeth

WASHINGTON (Reuters) - Japanese researchers said on Sunday they had grown normal-looking teeth from single cells in lab dishes, and transplanted them into mice.

They used primitive cells, not quite as early as stem cells, and injected them into a framework of collagen, the material that holds the body together.

After growing them, they found their structures had matured into the components that make teeth, including dentin, enamel, dental pulp, blood vessels, and periodontal ligaments.

No Brittish or redneck jokes here because they would be quite gratuitous.
