The simple addition of vitamin C to cell culture medium can induce extensive remodeling of the cellular epigenome and facilitates reprogramming of somatic cells to pluripotency. A new study shows that the activity of the enzyme TET1 can inhibit or enhance reprogramming efficiency, dependent on the presence or absence of vitamin C.
