Cells work around the clock to deliver, maintain, and control every aspect of life. And just as with humans, communication is a key to their success.
Every essential biological process requires some form of communication among cells, not only with their immediate neighbors but also to those significantly farther away. Current understanding is that this information exchange relies on the diffusion of signaling molecules or on cell-to-cell relays.
Publishing in the journal Developmental Cell, a research team at Kyoto University’s Graduate School of Medicine reports on a novel method of communication relying on ‘mechano-chemical’ signals to control cell movement. The research group focused on a fundamental pathway—MAPK/ERK, or ERK pathway—and were able to demonstrate how the movement of a single cell could trigger a cascading reaction resulting in the migration of a cell collective.
