For stem cells, bigger doesn’t mean better

A new study suggests that enlargement of stem cells contributes to age-related decline in function. The researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to perform their normal function -- replenishing the body's blood cells -- as they grow larger. When the cells were restored to their usual size, they behaved normally again.
