Recent breakthroughs in making stem-cell based human embryo models are raising urgent questions about to what extent they should be treated like natural embryos and whether they are open to misuse.

A team of researchers in the United States and United Kingdom say they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm.
