Study: New teeth can be grown from human urine

Scientists in China have released a new study which shows that new teeth can be "grown" using stem cell research and human urine.

According to the study, which was posted in the journal Cell Regeneration on Tuesday, stem cells can help regenerate teeth using a person's own human urine induced pluripotent stem cells.

The integration-free human urine induced pluripotent stem cells (ifhU-iPSCs) were combined with cells from mice teeth that are capable of developing into connective tissues, blood, and lymphatic and blood vessels.

Within three weeks, scientists say they had tooth-like structures with a success rate up to 30%.

Scientists say they found "enamel-secreting ameloblasts" in the tooth-like structures, which had physical properties such as stiffer material and hardness found in the regular human tooth.

"The tooth-like structure contained dental pulp, dentin, enamel space and enamel organ."

However, the "teeth" were not as hard as natural teeth.

While the research is not immediately going to lead to new options for dentists, researchers say it could lead to further studies towards "the final dream of total regeneration of human teeth for clinical therapy."
