Synthetic Human Embryo With No Brain And Heart: Baby ‘Made’ Without Sperm Or Eggs

In a groundbreaking development, scientists have created synthetic human embryos from stem cells - without the need for sperm or eggs! By using stem cells, scientists have eliminated the need to use eggs and sperm for the production of human embryos. How about that now, right?

Everything You Need To Know About Synthetic Human Embryo Creation

It has been reported that a team of researchers in the United States and the United Kingdom have created the world's first synthetic human embryo-like structures from stem cells, which do not require the use of eggs or sperm [1].

How Does A 'Synthetic' Embryo Look?

It is created from stem cells and, therefore, does not have a beating heart or a brain. However, it does contain the cells that transform into the placenta, yolk sac, and embryo.

Synthetic Human Embryo: What Are The Benefits?

Researchers believe these model embryos, which resemble embryos at the earliest stages of human development, could offer important insights into genetic disorders and the underlying causes of recurrent miscarriages [2].

There is a report in The Guardian stating that these synthetically created embryos may provide essential information regarding the biological causes of recurrent miscarriages [3].

"Our human model is the first three-lineage human embryo model that specifies amnion and germ cells, precursor cells of egg and sperm," Prof Magdalena Żernicka-Goetz, of the University of Cambridge and the California Institute of Technology told the Guardian before the talk. "It's beautiful and created entirely from embryonic stem cells."

Synthetic Human Embryo Raises Ethical Concerns

As the lab-grown entities are not subject to current legislation in the UK and most other countries, this research also raises serious ethical and legal issues.

For example, there is a lack of clarity about who is responsible for the safety and welfare of lab-grown entities and who will be held accountable if something goes wrong. There is also the question of what rights, if any, these entities should have.

"Unlike human embryos arising from in vitro fertilization (IVF), where there is an established legal framework, there are currently no clear regulations governing stem cell derived models of human embryos. There is an urgent need for regulations to provide a framework for the creation and use of stem cell derived models of human embryos," other experts added [4].

Additionally, it remains unclear whether these structures are capable of growing into living organisms in theory.

On A Final Note...

"I just wish to stress that they are not human embryos," Zernicka-Goetz said. "They are embryo models, but they are very exciting because they are very looking similar to human embryos."

"And it is a very important path towards the discovery of why so many pregnancies fail, as the majority of the pregnancies fail around the time of the development at which we build these embryo-like structures," the study head added.
