Synthetic mouse embryos can be created in the laboratory without sperm, eggs or uterus. These are embryo models derived from stem cells instead of synthetic embryos as such.
The embryo is the perfect starting point to generate organs and the best '3D bioprinter' This is the key to being able to create mechanisms that allow us to make stem cells differ from the specialized ones in the body or directly form entire organs, says Jacob Hanna of the Weizmann Institute of Science in Israel.
