Scientists at Johns Hopkins Medicine 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. The ...

Much like an ant colony or even people in an office, cells in the body must work together to accomplish their tasks. In all cases, this cooperation depends on communication. Ants do it by smell, people by sound, and, as shown ...

Four teams of researchers from multiple institutions in South Korea, the U.K. and China, working independently of one another, have made progress in understanding how mutations accumulate in human cells over time. All four ...
A protein that causes a cell's skeleton to bend, allowing it to twist the cell into different shapes, could be key to how cells divide according to University of Warwick scientists.

The human body is made up of trillions of cells that divide throughout a person's lifetime. Each time a cell divides, its genetic material is copied and reproduced so the duplicate carries the same information. This process ...
