Plant your teeth for ... mice

In the magazine Proceedings of the National Academy of Science published a strange work by the University of Tokyo scientists. They have replanted the fallen teeth for the mouse. And it is very likely that this success will soon be popularized in countries' 'Molars' rooms.

The group of Tokyo University scientists led by Takashi Sudzi studied embryonic cells that created teeth in mice. After taking these cells from mouse embryos, they split them into two types - epithelial cells and mesenchymal cells - then combine them into the embryonic tissue of the embryo.

Takashi Sudzi explained: ' We did that to prove that, in case of people, instead of embryonic cells, programmed and programmed stem cells can be used again in different forms. of embryonic cells, then on their basis, produce embryonic tissues for dental implants '. After a few days, cultivating embryonic tissues in the nutrient medium, the scientists implanted mice into the very place of the original tooth that was extracted.


36 days later, the first teeth appeared, and 49 days the teeth reached normal size at the old position, becoming natural teeth to chew food. The structure and properties of new teeth are very similar to natural ones, although they may be slightly different in shape. They will certainly adjust to the same old teeth.

Scientists also consider developing a new tooth just like any other organism takes place in the ' enclosure ' of other tissues. In addition, the teeth have complex structure and the development of parts in a tooth must be synchronized. For example, the development of tooth enamel, for example, cannot exceed the growth of blood vessels and nerves inside the root.

Broadly speaking, the development of any organism also needs a ' consensus ' of the cells, at each stage, they must wait for each other in the process of specialization. The immune system, too, has to wait for the developing organs. It has an ' obligation ' to identify strange cells, considering them to be dangerous factors.
