Two major problems with this.
First, if an embryo is produced and stem cells harvested, the fact of the matter is that A HUMAN EMBRYO IS KILLED. Period. It doesn't matter if the embryo is a leftover from IVF or "produced" for the sole purpose of isolating stem cells. Either way a human being is killed and that is plain WRONG.
Second, I get very upset with these reports of "new" ways of producing embryos. I have a PhD in molecular biology and teach college biology, so I know what I'm talking about. There isn't anything new with introducing a somatic cell's DNA into an unfertilized egg and then stimulating it to begin dividing. It's the same old story, repackaged to make it more acceptable to the sheeple.
By your definition, a human embryo is flushed away (killed!) once each month throughout a nubile female’s lifetime, unless she becomes pregnant. Also, the pill flushes an embryo away, fertilized or not, once each month.
These people are finding ways to use clone tissue for stem cells instead of fertilized embryo tissue (read potential person), why do you have a problem with that, Mr or Ms, microbiologist?
 Absolutely. And you don't have to be a microbioligist to have figured this out.
