>However, the purpose of the embryo is to provide an ethical way of monitoring early human development. Synthetic embryos would not be allowed to progress beyond a matter of weeks.
Sureeeeee... Until some will be
>During the first 14 days after an egg is fertilised by a sperm, the nascent embryo undergoes dramatic changes. It is at this point that myriad developmental disorders and birth defects can arise, but the cause of these is poorly understood.
The first two weeks are also a major source of miscarriage.
Speaking to the BBC, co-author Professor Jacob Hanna, from the Weizmann Institute of Science, said: ‘It’s a black box and that’s not a cliche – our knowledge is very limited.
"Jacob Hanna"... What are the odds?
>The latest breakthrough, published in the journal Nature, also used stem cells – and the team describes their results as the first ‘complete’ embryo model, one that mimics key cells and structures throughout the first two weeks of development.
‘This is really a textbook image of a human day-14 embryo, [which] hasn’t been done before,’ said Professor Hanna.
‘It closely mimics the development of a real human embryo, particularly the emergence of its exquisitely fine architecture.’
Across the world teams are racing to develop better ways to understand this crucial time. Earlier this year a team from the University of Cambridge and California Institute of Technology created synthetic embryos using only stem cells.
"stem cells"... AKA foreskins...
