ABSTRACT

Cells are highly complex living entities that contain a number of specialized organelles embedded within the cytoplasm. Cytoplasm and cellular organelles exhibit viscoelastic properties (i.e., they are adequately described neither as solid bodies nor as ¢uids). In addition, cytoplasm and the organelles form microdomains that differ in their mechanical properties. Investigating mechanics on a microscope scale seems strange in a biomedical world that considers genomics, proteomics, and the interactions of signal transduction chains as the main clues for understanding how a cell
