Human embryos made without eggs or sperm have been created in a scientific breakthrough which is bound to raise serious ethical and legal questions.

They were produced in a joint project between Cambridge University and the California Institute of Technology and resemble embryos in the earliest stages of human development.

They do not have the beginnings of a brain or a beating heart, but do include cells which would go on to form the placenta and yolk sac.

Scientists believe that their finding could provide significant insight and aid research into rare genetic disorders and the biological causes of miscarriage.

But the synthetic embryos are not covered by laws in the UK or in most countries around the world, meaning that they come with serious ethical and legal issues regarding the use of human embryos in a lab.

Until this breakthrough, scientists had to adhere to the 14-day rule which meant they were limited to allowing embryos to develop in a lab for a maximum of two weeks.

After this point researchers would have to wait until further along its development to pick up their study, relying on pregnancy scans and embryos donated to research.

The desire to understand this period of an embryo’s development – which starts at day 14 and ends around day 28 – was the main motivation behind the work to create synthetic human embryos.

Professor Magdalena Zernicka-Goetz, a fellow at the University of Cambridge, described the work yesterday at the International Society for Stem Cell Research’s annual meeting in Boston: ‘We can create human embryo-like models by the reprogramming of [embryonic stem] cells.’

Before the talk, she told The Guardian: ‘It’s beautiful and created entirely from embryonic stem cells.’

While it is not yet clear if the synthetic embryos could continue developing beyond their early stages, implanting them into a patient’s womb would be illegal and there is no near-term prospect of them being used for medical purposes.

Robin Lovell-Badge, the head of stem cell biology and developmental genetics at the Francis Crick Institute in London, told The Guardian: ‘The idea is that if you really model normal human embryonic development using stem cells you can gain an awful lot of information about how we begin development, what can go wrong, without having to use early embryos for research.’

Discussing the ethical issues surrounding the findings, he added: ‘If the whole intention is that these models are very much like normal embryos, then, in a way, they should be treated the same.

‘Currently in legislation they’re not. People are worried about this.’

  1. So, are these synthetic human embryos Alphas, Betas, Gammas, Deltas, or Epsilons?…ringing Aldous Huxley…. who is likely no longer with us…. Okay, okay….ringing Nuval Noah Harari… hackable animals, right? And speaking of “Noah,” are we in those “days”? (Matthew 24:37-39)

  2. Yes and I would think that you need at least 100 thousand Arks. to save the good people on this earth and some of the animals. We have to change … We have to save our Earth. And be willing to fight for our lives….

  3. Awwwww how sweet of them.. gonna help fix the miscarriage problem.. THEY CREATED!!! I have a friend whose 26yo daughter has had 3 miscarriages in past 2yrs.. she’s had THREE EFFIN SHOTS of course… Most women don’t even get pregnant 3 times in their life let alone 3 miscarriages!! But.. as the line goes.. Some folks you just can’t reach.. in all 3 she hasn’t made it past 4 weeks.. if I had to bet.. I’d bet she never has a child.. and that’ll probably end up being a blessing.. who knows how that child might turn out.
