Dec 08, 2020... To be an expectant mother, or the anxious partner of one, is to be keenly, even agonizingly aware of how chemicals affect a developing life. The basic advice is well known, and obsessively followed: Alcohol in strict moderation, and no nicotine at all. Don’t mess with mercury. Folic acid is your friend. More protein and less caffeine. Stay away from BPA, PBCs and PFA, and generally make an enemy of the unpronounceable.

In this fascinating video produced by the BBC, Prof. Jacob Hanna from Weizmann’s Department of Molecular Biology joins several global experts to discuss embryonic growth outside of the womb.
Hanna and his team made history by growing mouse embryos externally, and Hanna believes in the next ten years clinical trials in humans could be possible.
The potential impacts of growing human fetuses in a synthetic womb are wide-ranging, saving premature babies too underdeveloped for traditional incubators, preventing life-threatening pregnancy complications, and providing an opportunity for people who are unable to conceive for a variety of reasons, to have children.
Aug 01, 2022... REHOVOT, ISRAEL—August 1, 2022— An egg meets a sperm – that’s a necessary first step in life’s beginnings, and it’s also a common first step in embryonic development research. But in a Weizmann Institute of Science study published today in Cell, researchers have grown synthetic embryo models of mice outside the womb by starting solely with stem cells cultured in a petri dish – that is, without the use of fertilized eggs. The method opens new horizons for studying how stem cells form various organs in the developing embryo, and may one day make it possible to grow tissues and organs for transplantation using synthetic embryo models.
Sep 05, 2023... REHOVOT, ISRAEL—September 6, 2023—A research team headed by Prof. Jacob Hanna at the Weizmann Institute of Science has created complete models of human embryos from stem cells cultured in the lab – and managed to grow them outside the womb up to day 14. As reported today in Nature, these synthetic embryo models had all the structures and compartments characteristic of this stage, including the placenta, yolk sac, chorionic sac and other external tissues that ensure dynamic and adequate growth.
