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 ...

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.

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 ...

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, ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...
