The study, published in the journal Nature Cell Biology, found that cells use a combination of active and passive processes to maintain their shape. Active processes involve the use of energy to change the cell's shape, while passive processes involve the use of physical forces to maintain the cell's shape.
The researchers found that the active process of cell shape maintenance involves the use of molecular motors to move the cell's cytoskeleton. The cytoskeleton is a network of protein filaments that provides the cell with its shape and structure. The molecular motors move the cytoskeleton filaments in a coordinated way, which changes the cell's shape.
The researchers also found that the passive process of cell shape maintenance involves the use of physical forces to resist the forces that would otherwise cause the cell to change shape. These forces include the force of gravity, the force of the surrounding fluid, and the force of the cell's own internal pressure.
The researchers found that the two types of motion work together to maintain the shape of cells. The active process of cell shape maintenance provides the cell with the ability to change its shape, while the passive process of cell shape maintenance provides the cell with the ability to resist the forces that would otherwise cause the cell to change shape.
The researchers say that their findings could have implications for understanding how cells function. For example, they say that their findings could help to explain how cells move, how cells divide, and how cells interact with each other.
