During formation of multi-cellular organisms, cells need to talk to each other to make critical decisions as to what kind of cell to become, as well as when and where to become that cell type. The Notch signaling system allows cells to directly talk to each other to program almost every cell type in the body. Now, researchers from UCLA's Jonsson Comprehensive Cancer Center have shown for the first time that the mechanical force produced by cell-cell interactions is critical for programming by the Notch signaling system.
