02 Mar Researchers find safer way to produce stem cell alternative
Skin cells transformed without worrisome use of viruses
Scientists have developed what appears to be a safer way to create a promising alternative to embryonic stem cells, boosting hopes that such cells could sidestep the moral and political quagmire that has hindered the development of a new generation of cures.
The researchers produced the cells by using strands of genetic material, instead of potentially dangerous genetically engineered viruses, to coax skin cells into a state that appears biologically identical to embryonic stem cells.
