Oct-4: The almighty POUripotent regulator?

Abstract

Oct-4 plays an essential role as a central regulator of the undifferentiated state. Grinnell et al. demonstrate for the first time that Oct-4 by itself has the ability to reprogram committed somatic cells, inducing their dedifferentiation by reverting them to a more developmentally potent state. This study provides evidence that Oct-4 might be the master regulator of the pluripotent state in mammalian cells. © 2007 The Society for Investigative Dermatology.
