People lose teeth for all sorts of reasons, whether it’s through neglect, age, or sports injuries. A team of Chinese scientists from the Guangzhou Institute of Biomedicine and Health is working on an unusual way to replace those missing chompers.
The researchers derived stem cells from urine as a starting point. The experiment involved combining those stem cells with material from mice. Implanting it back into mice resulted in the growth of what looks like little teeth.
“The tooth-like structure contained dental pulp, dentin, enamel space, and enamel organ,” the researchers reported.
