Stem cell breakthrough turns out to be a lot less than first advertised

September 25, 2006

Advanced Cell Technology’s scientists were trying to work out a nondestructive recipe for producing stem cells, but the initial stage of the work still required the sacrifice of some embryos. In fact, the company used 91 cells from 16 donated embryos to get the first two stem cell lines. None 0f those embryos, of course, could be implanted afterward — all were destroyed.
