Scientists report they have grown the early stages of a human embryo-like entity without using sperm, an egg or a womb.
The ’embryo model’ even releases hormones that triggered a positive pregnancy test.
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.
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.’
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.
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.
The team used a cocktail of chemicals to ‘coax’ the stem cells into transforming into four key embryonic cells – epiblasts, trophoblasts, hypoblasts and extraembryonic mesoderm cells.
And what could go wrong with this program, Mr. Woods? I’d love to send you my latest novel. You would appreciate the content.
If ET Greys exist, then it’s likely the way they are produced–rampant arrogant stoooopidity.
Perhaps they should do science with Raven and its fellows to produce life worth living?

Who would be surprised if we then got the planet of the apes?
Nevertheless, it would be reassuring to know that the matter is in the hands of gifted dart players instead of those of gender-qualified experts.
women are too busy getting abortions…

Fyi At the moment, the annual meeting of non-commissioned pompous people is taking place again at the 78. UNGA 2023 The General Debate of the seventy-eighth session will be held from Tuesday, 19 September to Saturday, 23 September, and on Tuesday, 26 September 2023. The UN High-level Political Forum on Sustainable Development (HLPF), also known as the SDG Summit, will be held on Monday, 18 September and Tuesday, 19 September 2023. The UN General Assembly will convene three High-Level Meetings on health during its 78th session (UNGA 78) in New York in September 2023. These present a historic opportunity for… Read more »
LOVED–“…annual meeting of non-commissioned pompous people…” Very well stated and SO funny.
Patented Life? “Since the regenerative effect of stem cells is based mainly on the autocrine production of growth factors, immunomodulators and other bioactive molecules stored in extracellular vesicles, these structures can be isolated and used instead of cells for a novel therapeutic approach called “stem cell-based cell-free therapy. . . . There are four main sources of stem cells, i.e. embryonic tissues, fetal tissues, adult tissues and differentiated somatic cells after they have been genetically reprogrammed. And as we’ve continued to see with wicked injectable medicine, WHO knows what else are the binary attachments — XMMr, HELA, SMV? Ideological infanticide… Read more »
Interesting links, thank you.
These bunglers haven’t the faintest idea how life works. Their ‘science’ is that of idiots ‘a fool with a tool is still a fool’. They seriously think the universe was created by trial and error, so now they ‘do too’ – and also ignore any real scientific insight.
