Now research from Rockefeller University shows that having too many stem cells, or stem cells that live for too long, can increase the odds of developing cancer. By identifying a mechanism that regulates programmed cell death in precursor cells for blood, or hematopoietic stem cells, the work is the first to connect the death of such...
