The organizer, a long-theorized cluster of cells that helps organize and direct embryonic development, has been demonstrated to be present in human tissue for the first time, reports a paper published online this week in Nature. The study provides a new model for early embryonic development and suggests that the organizer is highly conserved across the animal kingdom.
