Breeding teeth in kidney mice

Japanese biologists have grown a real tooth from the implant in the kidneys of experimental mice.

Japanese biologists have previously grown mouse teeth in the lab. However, it is only teeth that grow from the jaw and it takes up to 40 days for them to mature. The artificial teeth this time grow from mouse kidneys and the time to become a complete tooth is also shortened.

For the first time, scientists have grown teeth from artificial tissue implanted in the kidneys of mice.

Chairman of the research project, Professor Takashi Tsui, Tokyo University (Japan) said his new method 'saves about 10 days. It's time to experiment on people, but this is only the first step, anyway. '

The topic group includes scientists at Tokyo University and Tohoku University who combine different stem cells to create 'nucleus' . Those 'nuclear' cells then divide and grow themselves, by interacting with each other to form dental tissue. They used plastic to cover these tissues and then implanted them into the kidneys. Here the teeth gradually mature, temporarily called 'teeth' .

At this time, they put the implant into the gums (gums) of another mouse. Meet the appropriate environment, the teeth sprout 'live' , associate themselves with nerves and blood vessels, become 'true teeth'.

The researchers hope, soon, that the method of creating teeth from their own ' stem cells ' should not be eliminated will be applied in practice to replant those who have had teeth removed. To replant, especially the tools that are prone, lose all teeth because of age, can eat better than current dentures.

In addition, it has been seen that tooth decay is the cause of many diseases and affects the mind. No matter what new benefits a tooth will bring.
