Samantha Morris, Ph.D.,¬†Assistant Professor of Developmental Biology and Genetics at Washington University School of Medicine in St. Louis, recently published an article in Nature. The article, “Cell identity reprogrammed,” focuses on¬†John Gurdon’s seminal paper published in Nature in 1958, which challenged the widespread theory that differentiation is an irreversible process. Gurdon, along with colleagues Tom Elsdale and Michael Fischberg, demonstrated nuclear reprogramming of cell identity, forming the basis of today’s cell-reprogramming field.
