Cell cycle has need for speed in iPS cell reprogramming

Last week, the news that exposing mature cells to stressful environments such as low pH can induce a stem cell-like state was greeted with much excitement, as stimulus-triggered acquisition of pluripotency cells (STAP cells) joined embryonic stem cells (ES cells) and induced pluripotent stem cells (iPS cells) as a cell type that might ultimately provide materials for autologous cell transplants. But iPS cells, too, made progress last week. A study published in the Jan. 30, 2014, issue of Cell showed that the likelihood of blood-forming cells transforming into iPS cells when they were treated with reprogramming factors could be increased by speeding up their cell cycle.
