For nearly two decades, the medical world and the American public have grappled with the lightning-rod topic of stem cells, in particular the controversy surrounding cells from human embryos. But when researchers four years ago successfully “reprogrammed” adult body cells to become stem cells, some thought the ethical debate was nearly over. Those redirected cells, known as induced pluripotent cells, or iPS cells, show potential as therapy.
“The benefit is they require no destruction of human embryos,” says Mayo Clinic hematologist/oncologist C. Christopher Hook, M.D., an author reviewing the science and ethics of stem cell technologies in the July issue of Mayo Clinic Proceedings. “The hope is that these cells may make embryonic stem cells unnecessary, but, according to the stem cell scientists, we’re not there yet.” Read more
