Inside every human body, a quiet army of blood-forming stem cells works around the clock. They produce red blood cells, white blood cells, and the immune cells that fight off disease. With age, these cells falter — and when they do, the consequences range from chronic fatigue and immune decline to blood cancers and systemic inflammation.
Now, scientists at the Icahn School of Medicine at Mount Sinai in New York City have identified why these cells age — and demonstrated that reversing it is possible, at least in mice.
