Abstract

We investigated the nanometer scale height fluctuations of 3T3 fibroblast cells with the atomic force microscope under physiological conditions. A correlation between these fluctuations and lateral cellular motility can be observed. Fluctuations measured on leading edges appear to be predominantly related to actin polymerization-depolymerization processes. We found fast (5 Hz) pulsatory behavior with 1-2 nm amplitude on a cell with low motility showing emphasized structure of stress fibers. Myosin driven contractions of stress fibers are thought to induce this pulsation.
