Scientists managed to develop the first full-fledged embryo without the use of eggs or sperm. And the model of the fetus, according to scientists, is not a real human fetus, but it contains all its parts.
The embryo was made from stem cells. These are the cells that can still develop into all types of cells in the body. Because the scientists added special substances to the stem cells, they turned into the first cells to form in a real human embryo a few days old.
After this specialization, large quantities of these cells were collected. Part of it took the form of a human embryo, researchers from Israel’s Weizmann Institute of Science wrote in the scientific journal. nature.
These studies are important to better understand human development. Little is known about the first two weeks of human life, which is a very sensitive period. At that point, the risk of miscarriage and malformations is greater. To prevent this, it is important to learn more about this early development.

The fetus “lives” fourteen days
Scientists assert that it is immoral, illegal, and moreover, impossible to place a fetus in the womb and allow it to grow into a full-fledged human being. Therefore, the experiment was terminated after fourteen days.
And in many countries, this is the limit for testing on real human embryos. But because this model is not a real fetus, this research does not fall under this law. However, due to the sensitivity of the subject, the scientists decided to stop the experiment.
Researchers are allowed to conduct experiments on live human embryos for a period of fourteen days. This agreement has been in force for forty years, but the question now arises whether this rule should be amended. Never before has embryo research been carried out for the full fourteen days.
