Summary:
Japanese researchers recently reported in Nature Methods they had successfully regrown a tooth from cells extracted from mouse embryos. The researchers were able to transplant the tooth into an adult mouse, and the tooth bud continued to grow to full size. However, researchers caution in that it is unclear whether the technique will be effective for re-growing teeth in humans, as the embryonic stem cells used by the researchers are difficult to obtain in large amounts and could be rejected as a foreign substance by a patient's immune system when they are transplanted in to the patient.
