Scientists at the Oregon Health and Science University and the Oregon National Primate Research Centre(ONPRC) have announced that they have succeeded in turning human skin cells into early-stage embryos. These can then be used create specialised tissue to treat disease.
Shoukhrat Mitalipov, Senior Scientist at the ONPRC, said the technique could help treat diseases, including Parkinson's.
A major step forward in science can now produce human stem cells by cloning. Some say it advances the search for medical treatments, others call for new laws to prevent cloning for ethical reasons.
