Scientists have discovered the origin of a unique type of cell known for its ability to support regeneration in the central nervous system. Their findings, published this week in the journal ...

Working with human breast and lung cells, scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of ...

Scientists say they have developed a computer model -- dubbed quantitative fate mapping -- that looks back in the developmental timeline to trace the origin of cells in a fully grown organism.

Malignant cells are genetically unstable and prone to develop chemotherapy resistance, whereas tumor vasculature is usually of host origin and genetically stable. Tumor endothelial microvessels ...

Australian scientists have pinpointed likely 'cells-of-origin', the source cells that can grow into breast cancer, in women carrying a faulty BRCA2 gene who are at high risk of developing the disease.

The idea that stem cells - special cells that divide to repair and generate tissues - might be the major determinant of cancer risk has provoked great debate in the scientific community. Some ...
