Does this really solve the ethical wicket of human embryo testing? Is tricking stem cells into forming an embryo really that different from fertilizing an egg with a sperm cell to form an embryo? Like, would this still develop into a functional human being if implanted into a womb?
The researchers stress it would be unethical, illegal and actually impossible to achieve a pregnancy using these embryo models - assembling the 120 cells together goes beyond the point an embryo could successfully implant into the lining of the womb.

It probably just raises further ethical questions.
