If that were true, the researchers would be using umbilical stem cells. It would be cheaper, more accessable, and less controversial. This company is not a bunch of ghouls looking to murder tiny, tiny babies. They are scientists looking to cure spinal cord injuries that leave people paralyzed in the best and most ethical way they know how. The embryonic stem cells were going to be destroyed anyway, so why not use them to save and improve lives. These are, by definition, undiferrentiated cells very early in the division process. I would agree there are certainly ethical limits to science, but I don't think this is getting anywhere near the line.
