As people age, so do their stem cells. Scientists have known for years that the stem cells that go on to become blood cells show significant signs of aging that sometimes lead to leukemia, excessive blood clotting and other diseases.
A new study from researchers at the University of California, Santa Cruz, reveals that even as blood stem cells age, the cells they turn into are often remarkably unaffected. The scientists provide evidence that specific “parent” cells may act as a buffer to protect the blood from the effects of aging.
