Scientists in Holland have managed to create synthetic embryos in a laboratory, by using cells from mice which are neither sperm nor egg. The results of this experiment have been published in Nature magazine.
It was pointed out that this discovery was not intended for cloning of people or animals, but rather, to shed light on the causes of early miscarriages, specifically at implantation stage.
The embryos were created in a dish, and were attached to the uterus wall in live mice for a number of days. It is believed that a study of this process can help in research on human fertility.
Research on embryos is difficult, both for technical and for ethical reasons. The synthetic embryo could therefore be the solution for more research in this sector.
