Given that an embryo's DNA is quite different from anyone who might be treated with same, I'm wondering what there is to it beyond human cloning. Personalized gene therapy would seem best done using the patient's own cells (DNA).
Evidently now even the research scientists themselves see the possibility of developing actual, successful therapies from embryonic stem cells as "remote." This isn't what they were saying back in 2005 when they were all angling for California's $3 BILLION taxpayer-funded embryo stem cell project.
