This year's meeting of the International Society for Stem Cell Research in Philadelphia, Pennsylvania, included a jam-packed session on the standards and methodologies of creating induced pluripotent stem cells. But although excitement around advances in reprogramming somatic cells shows no signs of abating, new ideas regarding the field are surfacing.

One announcement in particular may have consequences for induced pluripotent stem cells: It seems that ever reprogrammed cells can retain some echoes of their differentiated states, which researchers have nicknamed "cellular memory
