Summary:
Researchers at Advanced Cell Technology Inc., a U.S. company trying to push the margins of stem cell research, said on Friday they had grown human embryonic stem cells using a non-controversial method that did not harm the embryos. They said they had grown several lines, or batches, of the cells using a single cell taken from an embryo, which they then froze unharmed.
