Ken’s laboratory discovered “pioneer factors” that bind to silent chromatin, endow the competence for cell differentiation, and promote cellular reprogramming. Recently, his lab found broad chromatin domains that can resist pioneer factor binding and serve as impediments to cellular reprogramming; these domains appear to help commit cells to particular fates. Finally, his lab has unveiled how inductive signaling in the embryo leads to chromatin modifications that affect cell fate choices, thereby identifying specific enzymatic targets for small molecules to modulate cell fate control.
