Cambridge University scientists have successfully created a living mouse embryo from stem cells, a technique that could be used to create an artificial human embryo in the future.
After 2 kinds of mouse stem cells were mixed in the lab, they formed a mouse embryo after 4 days of growth in artificial chemicals that mimicked the natural womb.
Up until now, scientists have been experimenting with human embryos left over from in vitro fertilization (IVF) treatments, in which the sperm and eggs are combined in a lab. However, such embryos must be destroyed after 2 weeks.
Scientists are thus interested in having an unlimited supply of human embryos, which would not be dependent on sperm and eggs.
