Scientists have identified key changes to both chromosome structure and gene expression that affect stem cell function during aging. Using fruit flies, they found that these changes led to stem cell ...

After decades of hype and setbacks, scientists have made impressive progress into tricking stem cells into repairing organs. Stem cells (like the ones above, growing in petri dishes) are able to ...

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...

Aging taps us on the shoulder in many ways: wrinkles, thinning hair, loss of flexibility, slowing of the brain. But the process also unfolds at a more fundamental, microscopic level, as the energy ...

Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...

WASHINGTON (Reuters) - Mouse embryos created through a "virgin birth" process called parthenogenesis show that egg cells can be a source of valued embryonic stem cells, researchers said on Thursday.
