'Artificial Human Embryo' Experiment Succeeds... Is Pandora's Box Opening?

Artificial Embryo Created Using Embryonic Stem Cells
Equivalent to a 2-Week-Old Natural Embryo
Ethical and Legal Controversies May Arise

Researchers from the United States and the United Kingdom have succeeded in creating 'synthetic artificial embryos' using stem cells, sparking anticipated controversy. Although still in the very early stages of research, there are calls for laws and regulations to keep pace with advancements in life sciences.

The British media outlet The Guardian reported on the 14th (local time) that an international research team from the California Institute of Technology in the US and the University of Cambridge in the UK succeeded in early experiments with artificial embryos. Led by Professor Magdalena Zernicka-Goetz, the research team revealed their findings at the annual meeting of the International Society for Stem Cell Research (ISSCR) held in Boston, USA.

This research has not yet been published in academic journals. However, Professor Zernicka-Goetz explained at the conference, "We can create models similar to human embryos through reprogramming of (embryonic stem) cells."

The researchers had previously succeeded in creating artificial mouse embryos using stem cells last year, and those results were published in the UK-based journal Nature.

Professor Zernicka-Goetz explained that the artificial embryos developed in this study slightly surpassed the developmental stage corresponding to day 14 of a natural embryo. This corresponds to the 'gastrulation' stage. Gastrulation is a phase in fetal development where cells repeatedly divide and proliferate to form cell layers. The divided endoderm, mesoderm, and ectoderm at this stage later develop into various human organs.

If artificial embryos identical to human embryos can be created, it is expected that many secrets of human development, which have so far been close to unknown territory, can be uncovered. This could also lead to significant advances in future genetic disease research.

However, research on human embryos can raise serious legal and ethical controversies. Under current law, the cultivation of human embryos in laboratories is limited to 14 days, and beyond that stage, researchers must rely on imaging scans of pregnant women or donated embryos.

However, The Guardian reported that in laboratories in several countries, including the UK where this research was conducted, artificial embryo cultivation research is effectively proceeding beyond the scope of the law.

There are calls for more precise guidelines to manage and supervise artificial embryo research at research institutes. Robin Lovell-Badge, head of the Francis Crick Institute in London, told the media, "If these embryo models are made similar to normal embryos, they should be treated the same as normal embryos," adding, "Current laws do not reflect this, which is causing concern among researchers."
