Stem cell reprogramming made easier

Embryonic stem cells have the enormous potential to treat and cure many medical problems. That is why the discovery that induced embryonic-like stem cells can be created from skin cells (iPS cells) was rewarded with a Nobel Prize in 2012. But the process has remained frustratingly slow and inefficient, and the resulting stem cells are not yet ready for medical use. New research dramatically changes that: Scientists have revealed the "brake" that holds back the production of stem cells, and found...
