Rats born from artificial eggs

Japanese scientists have succeeded in creating female mouse eggs using cells extracted from the tail of this animal.

Scientists have succeeded in creating artificial eggs.

With this groundbreaking achievement, researchers from Kyushu University have not only created mouse eggs capable of fertilizing in the laboratory, but they have even succeeded in helping female mice pregnant with eggs. create this.

This technique involves extracting tissue cells from the rat's tail and "reprogramming" them into a stem cell to transplant into the egg. These eggs are then fertilized and put into a female mouse. Pups born from this unique process are perfectly healthy.

"This is the first time a fertilized egg has been produced from stem cells. This gives us the ability to create human eggs from their stem cells," said Professor Katsuhiko Hayashi. to speak.

"Currently, we need to closely monitor the quality of artificial mouse eggs. If the results are positive, this technique can be applied to people in the future."
