A team from the University of Tokyo has managed to develop the teeth of mice in the boxes of Petri. In the first place, a few cells were extracted from the dental fury of an early embryo of development. Then they were placed in the Petri boxes and got these cells to become also intoxicating. A mouse is removed from a tooth and put on the drunkenness it had created. The new tooth developed smoothly. However, scientists say that the development of human teeth still requires a long way, especially in terms of obtaining cells, since in the case of human beings they cannot use embryonic cells.
