Hairy Breakup

Alone, protein that replenishes chromosome ends finds capacity to fire up hair stem cells

Mary Beckman

Abstract: When actors Ronald Reagan and Jane Wyman split up, she remained a film performer whereas he moved on to politics. Likewise, a protein set free from its partner proves to have an unexpected talent--and this one has stem-cell biologists seeing stars. The protein component of telomerase, famous for maintaining chromosome ends, also stimulates stem cells in hair follicles, new research reveals. The results add to the growing body of evidence that telomerase performs multiple tasks.
