Pluripotent cells can give rise to all cells of the body, a power that researchers are eager to control because it opens the door to regenerative medicine and organ culture for transplants. But pluripotency is still a black box for science, controlled by unknown genetic (expression of genes) and epigenetic signals (biochemical marks that control gene expression like on/off switches). The Telomeres and Telomerase Group, led by Maria Blasco at the Spanish National Cancer Research Centre (CNIO), now uncovers one of those epigenetic signals, after a detective quest that started almost a decade ago.
