I probably shouldn't have focused on that type...
There are so many advances now in other types of stem cell treatments - adult stem cells, amniotic stem cells*, and even (crazy as it seems) the use of animal stem cells in humans in some ways. I just think its a big wave that has not hit...whether we use embreonic stem cells or not.
(*that's the other reason I regged amnio.co.uk - not just for the test that exists now, but for the possibility that we begin banking amnio fluid like we bank cord blood)
