Successfully obtained embryos were destroyed.
Scientists at the University of California have created hybrid embryos of human and sheep.
As told by the researchers, the cross-species creature got by introducing human stem cells into a sheep foetus. The proportion of human cells in the embryo does not exceed one thousandth percent. For ethical reasons, successfully obtained embryos were destroyed after 28 days after their creation.
Experiments to create hybrid embryos is carried out in order to explore the possibility of creating animal-chimeras. In the future, these animals can become a full-fledged organ donors for humans. According to scientists, this innovation will save many lives.
