In research that casts cells as curators of their own history, scientists have discovered that adult tissues retain a memory, inscribed on their DNA, of the embryonic cells from which they arose. The discovery led to one even more intriguing -- that the memory is fully retrievable: under certain conditions, cells can play the story of their development in reverse to switch on genes that were active in the fetal state.
