Can scientists learn cells' language? Researchers aim to decode cellular conversations
Key Points
Multicellular life depends on remarkable acts of cooperation. Every cell in the human body must sense what is happening around it, interpret signals from its neighbors and respond in ways that support the larger tissue. These chemical, physical and electrical messages help determine when cells grow, repair damage, fight infection or quiet down after a threat has passed—and tissue health depends on how well those parts come together.
