Scientists from Tufts University have made a discovery in dentistry - they were able to grow living teeth in the laboratory. To do this, cells from the teeth of cows and humans were used. They were placed in parts of pig teeth and then implanted into the jaws of mini-pigs. The experiment with mini-pigs was particularly successful: the teeth began to grow in the natural environment of the oral

As a result, three pups were born - two boys and a girl. In the future, they also want to bring back dodo birds, marsupial wolves and mammoths in a similar way
