The poster you mention probably wasn’t fearing a cure. It’s pretty well been proven there won’t be one from this. They were fearing that the girl would develop cancer from it. That’s what’s happened to people from embryonic stem cell injections. Those cells start massively dividing and developing into cancer.
I knew that Cletus.D.Yokel wasn't fearing a cure — I assumed that he feared that embryonic stem cells were used. I further assumed that the fear concerned the ethics of embryonic stem cells. Those were my assumptions — so, perhaps they were wrong.
My point was simply that, if embryonic stem cells were used, we wouldn't be left to wonder about it. That point would be front and centre, in every MSM story about the event.
I emphasized “successful” cure; because embryonic stem cell researchers have not been able to overcome the problem of rejection, by the recipient’s body. And (IMHO) they are unlikely to do so, without the same regime of anti-rejection drugs that transplant patients have to endure. I don't know much about the rate of cancer from embryonic stem cells.
