Researchers at the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have discovered a group of particularly long-lived blood stem cells in mice. These cells remain in a dormant state for an exceptionally long time while retaining their ability to generate new blood cells. This newly discovered cell population may be responsible for sustaining blood regeneration and immune defense throughout a mouse's entire life.
