This is a potentially tremendous story: bone marrow stem cells have been discovered in mice that have been changed into many types of body tissues. It won’t matter to the pro cloners who will just shrug their shoulders and keep on cloning. But it will matter to the rest of society.

I have long said that this debate will be won when and if people come to see that adult/umbilical cord blood stem cells have the therapeutic potential of embryonic stem cells. This takes us a big step closer to that tipping point.
