New stem cell research offers promise — and raises questions
New advances in stem cell research have the potential to save lives – but not necessarily for the reasons people think. In the late 90s and early 2000s, scientists and the press heralded the promise of these cells that appeared to have the ability to become whatever type of cell was needed to replace or fix damaged tissues. But major advances were slow to come, and the hype faded.
What's happening now: Instead of flashy, morphing cells, the stem cell therapies of today are much more subtle, work in unexpected ways, and it's not always clear why. Still, these advances are promising, so much so that today the FDA released a newly restructured framework for regenerative medicine, including stem cells, to help expedite applications for new therapies.
