New teeth for people to grow in urine

Can urine to help us in the cultivation dropped or extracted teeth? Scientists from the Chinese Academy of Sciences invented a technique of creating a "tooth germ" of the waste of the human body. These embryos can be implanted in the jaw.

According to scientists from China, extracted from the urine stem cells   one day help humanity to realize the old dream of growing new molars in place has fallen. While our body is able to replace only once baby tooth root. If it falls out or is removed and the tooth, the problem must be solved only with the help of crowns or implants. Meanwhile, in many animals new teeth   It grows almost all his life.

The Chinese Academy of Sciences in the course of experiments on mice zubopodobnye created structures that can be implanted in the jaw. This is the first hard tissue, which managed to get through stem cells Produced from the waste of the human body. The scientists used a new tissue culture system for growing cells to the level of tiny structures resembling new teeth .

According to the journal Cell Regeneration Journal, "tooth germ" became the first in the history of science solid organs or tissues made on the basis of pluripotent stem cells (PSC). Project leader Dr. Pei Danzhin made CPM emulate two different types of cells: mesenchymal of which there are three key components of the tooth (dentin, cementum and pulp) and epithelial cells, forming tooth enamel.

The final product was implanted into mice, and three weeks later they were in the mouth zubopodobnye structures that were very similar to human teeth on a number of parameters. (READ MORE)
