Interesting achievement.. Develop "fetus" without ovam or sperm.
Scientists have made a big step towards creating life in the laboratory without using sperm or eggs, by mixing two different types of stem cells to get an early form of the fetus.
The process of creating embryos from stem cells can provide an unlimited supply of identical embryos, which would be useful in medical research. It is expected that this development will shed light on one of the biggest causes of infertility, including the failure of the embryo transplant process in the womb.
Scientists say that the process, carried out on mice, can lead to the creation of a rat without the use of sperms or bots, within 3 years.
Scientists have collected two different types of embryonic stem cells extracted from mice. Once incorporated into a laboratory dish, she grew to form the early stage of the fetus, called "blastocyst" (hollow ball of cells), before being implanted in the uterus.
The cells initially led to changes in the uterus, such as those resulting from the 3.5-day natural embryo, but failed to properly complete cultivation.
In this regard, Professor Nicholas Rivon of the University of Maastricht, the main researcher in the study published in the magazine Nature, it is possible to create a viable embryo of a rat within 3 years, but the human embryo may take decades. The main use of embryos will be limited to the testing of medicines and research into the causes of infertility.
But experts warn that it may take up to two decades before using the technology developed to synthesize human embryos from stem cells.
