Review: Stem cells recovered from cloned human embryos
Scientists have recovered stem cells from cloned human embryos, a longstanding goal that could lead to new treatments for such illnesses as Parkinson's disease and diabetes. Experts called the work significant, but noted that a different, simpler technique now under development may prove more useful.
Stem cells can turn into any cell of the body. Scientists are interested in using them to create transplant tissue for treating disease. But transplants run the risk of rejection. So researchers had proposed creating tissue that used the patient's own DNA through cloning.
But in about a decade of trying, scientists had not been able to produce those stem cells from cloned human embryos. The success is reported Wednesday in the journal Cell by a team based at Oregon Health and Science University.
