Will inducing pluripotency in a somatic cell solve the embryonic stem cell controversy?

The controversy involving embryonic stem cell research at least in part comes from the need for a “very young cell” (aka a “pluripotent cell”, able to transform into any other older cell given the right biological milieu) to be directed biologically to become a mature cell that can function in healing.  Previously, in order to get a “very young cell”, researchers needed to go to the embryo.  New molecular biological techniques now allow older cells to become induced pluripotent cells by incorporating at least 4 key genes into their genome.  This obviates the need for embryonic cells.  The paper attached from the Annals of Internal Medicine, explains this in more detail.   Annals of Internal Medicine stem cell article
