Safer way to create stem cell alternative found

Washington: 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.

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.

"It's a leap forward in the safe application of these cells," said Andras Nagy of Mount Sinai Hospital in Toronto, who helped lead the international team of researchers that described the work in two papers being published online yesterday by the journal Nature.

Scientists are anxiously waiting for US President Obama to follow through on his promise to lift restrictions on federal funding for research on human embryonic stem cells.
