Embryonic Stem Cells without Conception?

According to a Reuters report, scientists have taken a nucleus from a mouse cancer cell and injected it into mouse egg cell. The resulting embryo was used as a source of stem cells. (Since this was a Reuters story, they couldn't resist adding a preposterous editorial comment at the end.)

I suspect that injecting the nucleus into an adult stem cell will produce an embryonic stem cell.

The story also mentioned that the reversal of the cancer process demonstrates a possible cure for cancer. The idiotarian left will take that as “The Religious Right is preventing a cure fof cancer!” It isn't that unless you intend to inject each tumor nucleus into an unfertilized egg … and there aren't enough of those to go around.
