Cells are able to sense their mechanical environment and to respond to it via appropriate cellular responses mediated via mechanotransduction. In particular, many cell types can regulate their levels of apoptosis, or programmed cell death, depending on which mechanical stimuli they receive. In the present communication, we show that calibrated levels of oscillatory shear strain, as measured by MR elastography, is sufficient to induce cellular death via apoptosis in the human colon cancer metastasis cell line, DHDK12.
