After more than a decade of trying to harvest the promise of embryonic stem cells, scientists have hit on a fascinating new approach that sidesteps them entirely. By adding genes to targeted cells in the body, they have been able change the basic makeup of those cells, turning them into potential disease-curing cells.
Clearly embryonic stem cell research has proven to be beneficial. It has lead to some of these other discoveries. But, early on there were the doubters . . . the one's who said there was greater "promise" in other forms of stem cell research. Even those who said ESCR would never work.
That's looking to be more true as we move forward.
