(wz) A California company said on Thursday it used cloning technology to make five human embryos, with the eventual hope of making matched stem cells for patients.
Stemagen Corp. in La Jolla, California, destroyed the embryos while testing to make sure they were true clones. But the researchers, based at a fertility center, said they believed their ready source of new human eggs would make their venture a success.
Other experts were skeptical about the claims, published in the journal Stem Cells. If verified, the team would be the first to prove they have cloned human beings as a source of stem cells, the master cells of the body.
There are several types of stem cells. Embryonic stem cells, made from days-old embryos, are considered the most powerful because they can give rise to all the cell types in the body.
The Stemagen team said they got five human embryos using skin cells from two adult men who work at the IVF center. They said they had painstakingly verified that the embryos were clones of the two men.
“We hope it is a bit of a turning point for many more studies,” Andrew French, who led the research, said in a telephone interview.
They used a technique called somatic cell nuclear transfer, or SCNT, which involves hollowing out an egg cell and injecting the nucleus of a cell from the donor to be copied — in this case, the skin cells from the men. more…
