A top scientist using stem cells from human embryos to cure disease and repair injuries will proceed with his work, he said in Tucson on Tuesday, despite a recent breakthrough showing the controversial embryos may no longer be needed.
That blockbuster breakthrough was announced last week by researchers in Wisconsin and Japan, who have discovered how to genetically program human skin cells to behave like embryonic stem cells.
That means the skin cells can develop into any cell in the human body — in the brain, heart, liver, muscle or bones — where they potentially can be used for lifesaving repairs or cures. Until now, only stem cells from human embryos — each a potential human life — could do that. Continue Reading »
