Research Abstract |
In this study, we developed a technique to measure the dynamic changes in intracellular stress distribution during cell stretching, and we also established to manipulate intracellular tension. Using these techniques, we investigated the effects of mechanical stimuli, such as cell stretching, on the division and proliferation of HeLa cells. We found that the cell spindle orientation during mitosis dramatically changed following cell stretching in perpendicular to the equator plane of the cells: HeLa cells divided in perpendicular to the stretch direction. These results indicate that cells divide according to mechanical factors provided by the forces applied to the cells. Our technique would be useful in investigating the mechanotransduction mechanisms of dividing cells.
