Scientists from Maastricht University announced that he had found a way to grow embryos without the use of egg and sperm.
To obtain such “ethically permitted” embryo, they needed two embryonic stem cells of different types. Combining them into a single unit, the researchers were able to result to the embryo at the blastocyst stage. This is one of the early stages of embryo development in mammals, occurring approximately at 5-7-th day after fertilization. However, while the resulting blastocyst does not develop further. As they say scientists, “the cells are not organized properly and look like a disorganized embryo”.
The purpose of creating blastocysts in the laboratory was to study the problems of embryo implantation in the uterine wall. This process in the rule should occur around the 3-5th day after conception. In some types of infertility implantation is not carried out.
To study the need for embryos, and receive them in a natural way associated with ethical restrictions and legal bans. Also, the embryos needed for research on the impact of drugs on the human embryo.
The new technology, according to scientists, within three years, allows you to grow a mouse created in a laboratory without the involvement of gametes. This means that after 20 years, it is theoretically possible to create a human embryo and, as a consequence of a clone army. Although today human cloning is strictly prohibited.
