I think they're on the verge of doing just that. Have you been keeping up with the UK's Human Fertilisation and Embryology Authority (I was going to say Orwellian-sounding, but no, I guess it's Huxleyan)? They are doing really freaky things with laboratory-based human reproduction. I think the idea now is to develop an "entity" which is just abnormal enough that it wouldn't be considered quite technically human. For experimental purposes.
Not that it matters. They don't seem to grasp the ethical objections to manipulating nascent humans. And the legal "barriers" are made of cobwebs. Thee are no meaningful limits at all.
I wasn’t familiar with the organization, but I went to the web site and did some reading. The only thing that I could find was cytoplasmic hybrid embryos, which are part human and part something else. As reprehensible as that is, it still requires an egg.
As far as I know, There is still no way to create an embryo without an egg. (I am close to 100% sure about this) If there is no embryo, then life is not being destroyed. This process sounds like it has tremendous potential, and I am encouraged by the attention it is generating. Basically, these stem cells are as beneficial as they can be, without being true embryonic stem cells. Nothing is really lost, because the benefit of embryonic stem cells has nothing to do with them coming from an embryo.
