One signal means different things to stem cells versus their progenyWhen researchers shut down hair follicle stem cells’ ability to respond to a protein, the cells began dividing prematurely forming a pocket of new cells (red). The same protein has a different effect on the stem cells’ progeny. More »

By tracking cells’ responses to signals, researchers found the speed at which the signal arrives has an unexpected influence on that decision. More »
