Scientists have turned skin cells into fully functional embryos, resulting in the birth of eight mice. This is a hopeful process that will one day help people and fertility problems. A team of Japanese researchers just took over cells from 10-week-old female mice. (This is 30 years old for humans). Next, they become skin cells that enter a special type of cell called induced pluripotent stem cells, which can divide and form different cells.

The pluripotent stem cells cover the chemicals that encourage them to specifically become immature egg cells. After adding some of the ovarian tissue from the mouse fetus, they become mature eggs. Finally, researchers used fertilized eggs and transplanted embryos to become surrogate mice. In total, 8 rats were born from 1348 embryos.
This is an exciting step forward, but there are also several major limitations. One is that it takes a lot of time and even when it does, the egg is not very healthy. After all, only eight babies are born from more than a thousand embryos.
It is hoped that eventually the same technology can be applied to human egg infertility, but it will take several years. We are much more complex than mice and have many ethical issues. But now we know that this method is at least possible.
