To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build.

Breast cancer stem cells wear a cell surface protein that is part nametag and part bull's eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug.

A study from Massachusetts General Hospital (MGH) researchers suggests that specific populations of tumor cells have different roles in the process by which tumors make new copies of themselves and grow.

A new study by researchers at the University of California, Los Angeles (UCLA) has discovered two adult stem cell-like subpopulations in adult human skin.

A team led by scientists at The Scripps Research Institute and the University of California (UC) San Diego has discovered a new type of dynamic change in human stem cells.
